Full textAbstract:
This thesis is motivated by Statoil's wish to localize people operating inside an onshore or offshore production facility. There are especially two benefits of such systems. By monitoring an operator's exposure to noise, vibration and harmful gases, short and long term damages can be avoided. In addition, a localization system would provide employees with a higher degree of safety in case of emergency. The aim of this thesis is to develop a prototype system for localizing people indoors as well as outdoors with use of an inertial measurement unit. As a consequence, challenges such as drift and signal noise, as well as magnetic interference are directed. Since the IMU is subject to drift, investigations on different sensor configurations must be conducted. Collected sensor data from the hip-mounted IMU are used for step detection, step length estimation and heading determination. By combining the results from these three approaches, a positioning estimate for the human operator is calculated using dead reckoning. Dead reckoning is a positioning method for determining an objects location based on a former position, velocity and direction.Experiments indicated satisfying performance by both the implemented step detection algorithm and the step length estimation model. However, the heading determination is subject to magnetic interferences when the sensor is applied in an industrial area. In an indoors environment are position error 2-4 meters after 22 meters walking. Performance in an outdoors environment are significantly better, with a position error of 10 meter after 400 meters. Integrating the suggested solution with another positioning system will increase system performance indoors and thus fulfill the aim of this thesis.

Full textAbstract:
This report covers the design methodologies and principles used to develop an automated telescope tracking system. The 1980’s Murdoch University owned telescope was the hardware used in this project and the challenges experienced were primarily due to mechanical failures or part specification.
With utilising open-sourced equipment came great benefit as many design ideas were easily implemented due to a large following of these devices. In fact much of the code required to have this project operational already exists on the internet and is freely available to download.
Overall, the project outcomes were not fully achieved but the project is deemed partially successful given the large amount of research and development future students can learn from.

The Airborne Seeker Test Bed (ASTB) is an airborne sensor testing platform operated by the Tactical Defense Systems group at MIT Lincoln Laboratory. The Instrumentation Head (IH) is a primary sensor on the ASTB. It is a passive X-band radar receiver located on the nose of the plane. The IH serves as a truth sensor for other RF systems on the test bed and is controlled by an onboard tracking system, the Seeker Computer. The Seeker Computer processes IH data in real-time to track targets in Doppler, angle, and range. From these tracks it then produces angle-error feedback signals that command the IH gimbals, keeping targets centered along the antenna boresight. Over three years, a new Seeker Computer was built to replace an old system constrained by obsolete hardware. The redevelopment project was a team effort and this thesis presents a systems-level analysis of the design process, the new Seeker Computer system, and the related team and individual contributions to software and digital signal processing research that took place during development.

Full textAbstract:
The purpose of this bachelor thesis is to present a tracking system for the Suaineadh satellite experiment. The experiment is a part of the REXUS (Rocket EXperiments for University Students) program and the objective is to deploy a foldable web in space. The assignment of this thesis is to develop a tracking system to find the parts from the Suaineadh experiment that will land on Earth. It is important to find the parts and recover all the data that the experiment performed during the travel in space. The implementation of this thesis investigates two different ways to track and find the experiment. The first way is to locate the experiment module by a Global Positioning System (GPS) and send the coordinates to a satellite modem, controlled by a programmed microprocessor. The other way is by using a radio beacon that sends a speciffic radio frequency. The results of this thesis presents a prototype for the tracking system with a GPS and the satellite modem and code example for the microprocessor. It also presents a working radio freqency beacon system on a Printed Circuit Board. The thesis had some unexpected incidents and had to change some directives. This rendered the work to take longer time then estimated. Despite the difficulties resulted this thesis in a working system to track the experiment.

International Telemetering Conference Proceedings / November 04-07, 1991 / Riviera Hotel and Convention Center, Las Vegas, NevadaThe primary objective of the Advanced Telemetry Tracking System Integration and Development program at WSMR was the development and evaluation of an advanced, almost totally digital servo tracking and control system. This was satisfied by replacing the aging analog servo tracking and control system in one of WSMR’s seven Transportable Telemetry Acquisition Systems (TTAS) with a Digital Control Unit (DCU), an Antenna Control Unit (ACU), and other related equipment, and then evaluating the performance of the resultant digital tracking system, referred to as the Advanced TTAS (TTAS-A). The ACU is the primary interface between the operator and the DCU. Through the ACU, the TTAS-A operator has independent control over each pedestal axis (elevation and azimuth) involving the selection of tracking mode and servo bandwidth. The DCU reports various servo system status and warning conditions back to the operator through the ACU. In this paper, a discussion of the TTAS-A servo system, with emphasis upon hardware external to the DCU, is presented. This includes the operation of servo position and rate loops, system status and warning conditions, and a description of the operator-to-system interface via the ACU display and control functions.

Electronics Art Inc. (EA) is one of the largest game companies in the world with offices all over the globe. A company the size of EA is dependent on many IT systems to maximize production and game development. In today’s competitive market, it is not uncommon that important supportive systems lack documentation due to short development times. These systems may be operative in the short run but may fail in a crisis situation when developers have no documentation of how the system works. An extremely important supportive system that EA use that lack documentation is the Worldwide Built Tracking System (WBTS). It was developed to protect EA’s intellectual property. The purpose of this thesis is to develop and provide an accurate documentation site for WBTS to assist both beginner and expert users at EA in order to improve the users’ productivity and insight of the system. The final result of this work provided the users a direct way to access WBTS system documentation. In this manner, minor questions are answered online. Precious time and resources are saved as basic questions no longer need to go through the EA support team. This enables the users to complete their work more quickly by finding the answers on the created documentation site.

Full textAbstract:
Object tracking is an important component in many applications including surveillance, manufacturing, inventory tracking, etc. The most common approach is to combine a surveillance camera with an appearance-based visual tracking algorithm. While this approach can provide high tracking accuracy, the tracker can easily diverge in environments where there are much occlusions. In recent years, wireless tracking systems based on different frequency ranges are becoming more popular. While systems using ultra-wideband frequencies suffer similar problems as visual systems, there are systems that use frequencies as low as in those in the AM band to circumvent the problems of obstacles, and exploit the near-field properties between the electric and magnetic waves to achieve tracking accuracy down to about one meter. In this dissertation, I study the combination of a visual tracker and a low-frequency wireless tracker to improve visual tracking in highly occluded area. The proposed system utilizes two homographies formed between the world coordinates with the image coordinates of the head and the foot of the target person. Using the world coordinate system, the proposed system combines a visual tracker and a wireless tracker in an Extended Kalman Filter framework for joint tracking. Extensive experiments have been conducted using both simulations and real videos to demonstrate the validity of our proposed scheme.

Full textAbstract:
The objective of this thesis is to demonstrate an indoor intruder location and tracking system with UltraWideBand (UWB) technology and use data compression and Constant False Alarm Rate (CFAR) techniques to improve the performance of the location system. Reliable and accurate indoor positioning requires a local replacement for GPS systems since satellite signals are not available indoors. UWB systems are particularly suitable for indoor location systems due their inherent capabilities such as low-power, multi-path rejection, and wide bandwidth. In our application, we are using UWB radios as a radar system for tracking targets in indoor locations. We also use Discrete Cosine Transform (DCT) to compress the UWB scan waveforms from the receivers to the main computer to conserve bandwidth. At the main computer, we use Inverse DCT to recover the original signal. The UWB intruder detection system has the indoor tracking accuracy of four inches. There are many military and commercial applications such as tracking firefighters and locating trapped people in earthquake zones, and so on. This thesis demonstrates the capability of a UWB radar system to locate and track an intruder to an accuracy of four inches in an indoor cluttered environment.M.S.Cp.E.

The P/ETS utilizes an off-the-shelf Global Positioning System (GPSFlight) which provides full-time tracking and display of all on-board transmitter-equipped elements. A line-of-sight wireless-to-fiber network system is employed to acquire and transport positional data to display systems within the range safety control tower. Utilization of P/ETS has indicated accurate tracking display in real time, particular advantages for night time operations, prevention of hazardous area intrusion, and relocation of miss-oriented personnel. This system is an economical solution for meeting the ground safety requirements within the confines of the Precision Impact Bombing and Laser Test Ranges.

The Incident Dispatching and Tracking System (IDTS) was developed to facilitate the technical support of an organization. IDTS provides a means by which a user may submit their issue/problem to the system and receive a unique trouble ticket number. This number can then be used to view the status of that record, minimizing the need for inquiries to the technical support team. IDTS also provides a dispatching function that assigns each trouble ticket to a technician that specializes in that type of issue. Finally, there is a reporting function that allows the technical support team to view the current technical status of the organization, generate statistics on previously submitted trouble tickets, and determine areas that may require assistance in the future.

Full textAbstract:
Automatic tracking of an object of interest in a video sequence is a task that has been much researched. Difficulties include varying scale of the object, rotation and object appearance changing over time, thus leading to tracking failures. Different tracking methods, such as short-term tracking often fail if the object steps out of the camera’s field of view, or changes shape rapidly. Also, small inaccuracies in the tracking method can accumulate over time, which can lead to tracking drift. Long-term tracking is also problematic, partly due to updating and degradation of the object model, leading to incorrectly classified and tracked objects. This master’s thesis implements a long-term tracking framework called Tracking-Learning-Detection which can learn and adapt, using so called P/N-learning, to changing object appearance over time, thus making it more robust to tracking failures. The framework consists of three parts; a tracking module which follows the object from frame to frame, a learning module that learns new appearances of the object, and a detection module which can detect learned appearances of the object and correct the tracking module if necessary. This tracking framework is evaluated on thermal infrared videos and the results are compared to the results obtained from videos captured within the visible spectrum. Several important differences between visual and thermal infrared tracking are presented, and the effect these have on the tracking performance is evaluated. In conclusion, the results are analyzed to evaluate which differences matter the most and how they affect tracking, and a number of different ways to improve the tracking are proposed.

Radio Frequency Identification (RFID) technology has been widely adopted by different industries for various purposes. While implementing a RFID system for personnel tracking in an industrial environment, such as a hospital, the tracking accuracy is not always satisfactory due to incorrect placement of RFID hardware, coarse system configuration or environment. This thesis proposes comprehensive optimization methods for improving the tracking accuracy of a RFID system for personnel tracking. The improvement is achieved from four perspectives including RFID data cleaning, experimental design, data fusion and simulation modeling. This research is based on a case study carried out in a local community hospital where a RFID system for personnel tracking has been implemented. Through applying the optimization methods, the tracking accuracy of the RFID system has been improved to 87.33%. The thesis provides a guideline for the hospital and other similar application environment to implement improvement methods on a RFID tracking system.

Full textAbstract:
Personal variations severely limit the performance of appearance-based gaze tracking. Adapting to these variations using standard neural network model adaptation methods is difficult. The problems range from overfitting, due to small amounts of training data, to underfitting, due to restrictive model architectures. In this thesis, these problems are tackled by introducing the SPatial Adaptive GaZe Estimator (\spaze{}). By modeling personal variations as a low-dimensional latent parameter space, \spaze{} provides just enough adaptability to capture the range of personal variations without being prone to overfitting. Calibrating \spaze{} for a new person reduces to solving a small optimization problem. \spaze{} achieves an error of \ang{2.70} with \num{9} calibration samples on MPIIGaze, improving on the state-of-the-art by \SI{14}{\percent}. In the introductory chapters the history, methods and applications of eye tracking are reviewed, with focus on video-based eye tracking and the use of personal calibration in these methods. Emphasis is placed on methods using neural networks and the strengths and weaknesses of how these methods implement personal calibration.QC 20210528

Full textAbstract:
Visual tracking is a classical computer vision problem with many important applications in areas such as robotics, surveillance and driver assistance. The task is to follow a target in an image sequence. The target can be any object of interest, for example a human, a car or a football. Humans perform accurate visual tracking with little effort, while it remains a difficult computer vision problem. It imposes major challenges, such as appearance changes, occlusions and background clutter. Visual tracking is thus an open research topic, but significant progress has been made in the last few years. The first part of this thesis explores generic tracking, where nothing is known about the target except for its initial location in the sequence. A specific family of generic trackers that exploit the FFT for faster tracking-by-detection is studied. Among these, the CSK tracker have recently shown obtain competitive performance at extraordinary low computational costs. Three contributions are made to this type of trackers. Firstly, a new method for learning the target appearance is proposed and shown to outperform the original method. Secondly, different color descriptors are investigated for the tracking purpose. Evaluations show that the best descriptor greatly improves the tracking performance. Thirdly, an adaptive dimensionality reduction technique is proposed, which adaptively chooses the most important feature combinations to use. This technique significantly reduces the computational cost of the tracking task. Extensive evaluations show that the proposed tracker outperform state-of-the-art methods in literature, while operating at several times higher frame rate. In the second part of this thesis, the proposed generic tracking method is applied to human tracking in surveillance applications. A causal framework is constructed, that automatically detects and tracks humans in the scene. The system fuses information from generic tracking and state-of-the-art object detection in a Bayesian filtering framework. In addition, the system incorporates the identification and tracking of specific human parts to achieve better robustness and performance. Tracking results are demonstrated on a real-world benchmark sequence.

Full textAbstract:
The use of robots is important in many areas of industrial automation. For reliable and safe operation, accurate and precise control of their activities is vital. The current drawback is, however the lack of accurate of position sensors, that are not subject to load variations and wear. Hence there is a need to seek an accurate external sensor that is not subject to such problems. Such external position determination is also important for safety and fault recovery considerations. For example, the sharing of working environments between humans and robots implies that the robot must work inside a tight working envelope. Position sensing is an essential input for determining the actual working enveloped occupied by the robot. The position being sensed and, better still, the predicted position it is moving into, will enable early detection of possible abnormal situations. Also, if the robot does fail, knowledge of its precise position would be valuable in aiding rapid fault recovery. Approaches to position detection have usually suggested the use of markers attached to the robot. These, however, can cause some load problems, besides needing special, additional equipment. This thesis proposes an approach to recovering the position of a robot visually, using a single, stationary camera, without the need for any special markers on the robot. The system exploits knowledge of the robot being monitored by employing a model-based approach. The basic principle is to find the values of state variables of a robot model that described the appearance of the robot from the scene captured on the image. The state variables here are the joint angles of the robot being monitored. The proposed model-based tracking system consists of various components. The feature extraction determines the robot features from the captured image, and a matching module finds possible correspondences between the extracted features and the modelled robot features. The correspondences thus obtained are then used by a state estimation component to recover the states that describe the position of the joints. A tracking module then uses the position that has been recovered, and a robot motion model, to predict the future positions of the joints. The proposed system was tested statically and dynamically with a number of image sequences captured off-line. The accuracy achieved was 5 cm in static mode and within 10 pixels when dynamically tracking.

Operating as a reorganized command resulting from a large Naval Special Warfare (NSW) community-wide reorganization, called NSW-21, Naval Special Warfare Group One (NSWG-1) identified a significant budgeting challenge. In late calendar year 2001, while NSWG-1 was working out the initial financial ramifications of its new organization, the Global War on Terror (GWOT) began. With the GWOT came extraordinarily large supplemental appropriations. These appropriations helped subsidize some of NSWG-1's new funding needs. Thus, NSWG-1 recognized it might face a future funding deficit if, and when, supplemental appropriations are discontinued. As a result, the NSWG-1 leadership formed a budget team determining how to more closely scrutinize the normal year budget to find discretionary funding for emergent needs. They executed improvements to NSWG-1's expenditure tracking system to capture more specific expenditure data upon which to base future spending decisions, and to establish a new baseline of normal, post transition needs. The purpose of this project is to document and analyze the improvements NSWG-1 made to its expenditure tracking system and how it serves as a performance measurement system.

They executed improvements to NSWG-1's expenditure tracking system to capture more specific expenditure data upon which to base future spending decisions, and to establish a new baseline of normal, post transition needs. The purpose of this project is to document and analyze the improvements NSWG-1 made to its expenditure tracking system and how it serves as a performance measurement system.

Approved for public release; distribution is unlimitedThe Auxiliary Tracking System (ATS) is being developed to allow for an accurate underwater tracking capability that can be deployed anywhere in the world. A simulation was created to determine the impact upon the relative accuracy of the system due to a normally distributed noise. The simulation was used to look at the impact of range between targets and the depth spacing of the suspended transducers on the relative tracking accuracy.

The purpose of this thesis is to build the tracking system for a photon-counting laser radar specifically a laser radar that has the ability to perform direct and coherent detection measurement at low signal levels with common laser, optics and detector hardware. The heart of the tracking algorithm is a Kalman filter, and optimal Kalman filter parameters are determined using software simulations. The tracking algorithm was tested against various simulated (software only) and emulated (with actual hardware) trajectories. We also built and tested the real-time tracking system hardware. The algorithms and methods proposed in this thesis achieve the objective of tracking a target at 1,500 km range to within 1-cm accuracy.

ITC/USA 2012 Conference Proceedings / The Forty-Eighth Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2012 / Town and Country Resort & Convention Center, San Diego, CaliforniaSurveillance and tracking using unmanned aerial vehicles (UAVs) is a growing field and to visually track an object independent of a flight path requires a video transmission and control system. Applications utilizing UAVs to track a stationary or moving target are plentiful, from military to local law enforcement; every application introduces an alternative to placing a human into an aircraft and increases the usefulness over a fixed position recorded video. Here we have introduced a cost effective video tracking system that will provide a constant video transmission, manual control for tracking, and further implement an automatic control system to automatically correct for the UAV's roll and yaw. The video tracking system has been designed to be cost friendly while constrained to be applicable for small UAV applications. We have detailed the successful design of our system that overcomes the imposed constraints in great detail in the sections that follow.

This research uses Micro-controller Unit (MCU) and five solar energy detecting devices to develop a set of two-axis sun tracking system. The system uses the sunshine formula to let the system determine the simulation position of the sun quickly. Another function is to fine-tune the system and determines the sun position accurately. This system uses microprocessor to fabricate the Micro-controller Unit, and assess the light source. It possesses energy saving, the best tracking function determination, and defends the illuminance interfere functions. Through simulation and analysis of the cloudy angle and the difference of latitudinal angle experimental result, it shows that the average tracking longitudinal angle is 4° ~ <1°. On the other hand, we utilize slope 45o angle to place the solar cell in the east, south, west, north, and measure the output voltage of sunny day in different positions. Compared with previous investigations, this main structure of the solar energy detecting device is to put the solar cell battery in the center, and then tracks the light source position by 90o angle, therefore we can obtain the maximum output voltage from the sun position.

It has been for a long time to develop systems of eye control, which are related to a variety of techniques, such as signal/image processing, characteristics of face identifying/tracking, action-mappings, etc. In terms of implementations, the acquisition of data can be done by either special instruments or by general devices. Such systems can be applied to many fields, for instance, military, medicine, entertainments, and other tasks that are fitted. And for the similar system, the performance differs due to the disparity of distinct situations and the way to use it. In this thesis, we present a system that takes a sequence of images of a user as inputs, and then integrates methods of elliptical model of head, dual states of eyes, deformable templates, and the most yield filter to track the user’s eyes. A coarse-to-fine strategy is used to rapidly locate the region of eyes and to get the information of eyes in order to translate into corresponding operations on machines. The experiment shows that our system is quite robust and fast so that it can help people who are unable to use physical body well.

In this thesis, the hand tracking system using Pixel-Based Hierarchical-Feature AdaBoosting (PBHFA), skin color segmentation and codebook model is presented. The purpose of this approach is to build a system that is able to solve problems in field of hand detection and object tracking. In task of detection, Haar-like features are well-known method and play an important role in the success of face detection. However, in the training process, the large number of possible Haar-like features in a standard sub-window becomes time consuming, which makes specific environment feature adaptation extremely difficult. For that reason, the PBHFA is introduced to detect a hand by significantly reducing the training time by a factor of 1500 compared to the traditional Haar-like features. Moreover, the PBHFA is also an effective solution to deal with the complex background environment, and which is considered as the main challenge of the hand detection. Yet, one of the disadvantages of the PBHFA is the false negative that is the consequence of appearance of complex background in positive samples. It is also the main problem of the former approaches. To reduce the effect of false negative, in this system, the skin color is employed for eliminating those areas which are not skin region. In addition, the false negative is often the background, so by applying the codebook model, we can easily segment the foreground from background to reject all of the candidates which belong to background. The final decision is based on the result of the three modules and the detected hand is then considered for tracking in the next step. Using the combination of the three modules not only achieves a high detection rate, but also able to solves problem of occlusion in tracking task. This advantage allows us to track the correct object even there are many detected hand in the scene and sometimes the tracked hand disappears. Also, most of the object tracking systems fail in case of moving camera. In this work, the proposed system has the capability to deal with the challenge in order to track the target when both of camera and the hand move, and thus it makes the system more effective

In recent years, most people make speeches or talks to spread out their latest information or ideas. Some of them use a camera with tripod to record the whole activity, others may hire a camera operator. However, it will cost lots of human resource. In addition, the quality of video recording depends on the skills of camera operators. Hence, in this thesis, we proposed a smart speaker tracking system to automatically record the whole speech. In addition, the proposed system uses the human detection and multiple kernel tracking schemes to automatically track and record the speaker via one PTZ camera. Furthermore, the omni directional camera is adopted to find the speaker’s position when losing the speaker’s position via the PTZ camera. Experimental results show that the proposed system can automatically tracking the speaker position. When losing the speaker’s position, the proposed system can relocate the speaker’s position by clicking the omni directional camera image manually.

Abstract This study aimed to develop a low cost buoyant solar tracking system, in order to enhance the efficiency of solar power generation. The buoyant solar tracking system contains two main modules. One is the automation photosensitive module consisting of the photosensitive element and automation control circuit of the control module; the other is buoyant module with water pumps and the leveling mechanism including buoyant balls. This design begins with the capture of sunlight by the photosensitive element, which passes over the signal to the automation module to control the water pumps, resulting in the difference of water levels in the East and West. The differential buoyancy causes the solar photovoltaic panels to synchronize with the angle of solar position, optimizing the power generation. Test results showed that the system can improve of 37.67% of the power generation of the solar cell panel.

The goal of this research is to develop a model-based tracking framework with biomedical imaging applications. This is an interdisciplinary area of research with interests in machine vision, image processing, and biology.
This thesis presents methods of image modeling, tracking, and data association applied to problems in multi-cellular image analysis, especially hematopoietic stem cell (HSC) images at the current stage. The focus of this research is on the development of a robust image analysis interface capable of detecting, locating, and tracking individual hematopoietic stem cells (HSCs), which proliferate and differentiate to different blood cell types continuously during their lifetime, and are of substantial interest in gene therapy, cancer, and stem-cell research.
Such a system can be potentially employed in the future to track different groups
of HSCs extracted from bone marrow and recognize the best candidates based on some
biomedical-biological criteria. Selected candidates can further be used for bone marrow transplantation (BMT) which is a medical procedure for the treatment of various incurable diseases such as leukemia, lymphomas, aplastic anemia, immune deficiency disorders, multiple myeloma and some solid tumors.
Tracking HSCs over time is a localization-based tracking problem which is one of the most challenging tracking problems to be solved. The proposed cell tracking system consists of three inter-related stages:
i) Cell detection/localization,
ii) The association of detected cells,
iii) Background estimation/subtraction.
that will be discussed in detail.

This report deals with the design of the Tracking Loop and those
functions involved with it, for a ship-borne Tracking Radar System.
The report begins by placing the problem in perspective from an
historical point of view by surveying some of the literature
available.
A realistic environment in which the radar could be expected to
operate is postulated in some deti.il. Following that, the actual
design of a tracker to suit that environment is conducted.
Simulations of proposed configurations were a major part of the
design methodology, as they best indicated the performance of the
loop. These were written in FORTRAN-77 on a VAX Computer and
displayed using modified PLOT-IO and PI.OT-21 software packages.
Since the design and simulation of the entire Tracking Radar System
was not covered in this dissertation, no major conclusions could be
drawn concerning the performance of the Tracking Loop in the overall
Tracking Radar System. Such results will have to await a full
system simulation such as that proposed later in this report.

The Surveillance System had used a greater deal of the Traffic controlled、Office Surveillance、Environment Surveillance、and House or community surveillance. In many traffic accidents, It is very important role of the monitor system and it solves a lot problems of traffic accidents. In public security, the surveillance system is pointer to be the powerful evidence. In personal House or community, the surveillance is a good private security service. It save your life. So far, the structure of surveillance system is made up of one CCD and Recorder System. The Image data from CCD is recorded one by one by Recorder System. There are two problems in this structure of surveillance system. Number one, The CCD is fixed and captures the sequence image in the fixed view. When the view is out of the CCD range, the CCD can’t capture the image data of out CCD rang. This will give the chance to the thief to burst into the house. Number two, the recorder system of traditional monitor system always recodes the images every second. If the moveable object in the view or not, the recorder system always recodes data. This will waste the recorder system resource. And the system recorded the image data that is almost unused for us. So we propose a ideal that tracking moveable object system. When CCD detects the moving object, the CCD will turn around to the moving objection and the center of CCD will focus the moving object like the human’s eye tracking the moving object. Beside, recorder system doesn’t record image data every second. As soon as CCD detects the moving object, the recorder system will start recording image data. This will reduce the restoring space.
