Abstract:

Three-dimensional visualization refers to the process by which graphical content is created using the Three-dimensional software. While working with Threedimensional visualization, different indoor positioning techniques can be used to detect and track the movement of objects. Combining these two technologies provide the ability to monitor a room and its objects in real time. Positioning is the process of recording the movement of objects or people. Positioning techniques can be used in many different areas such as emergent situations and tracking objects with potential risks as an aid. It is

Abstract:

The purpose of this thesis is to investigate the possibility and feasibility of a platform-independent positioning system capable of determining the location of mobile devices without imposing additional requirements on the hardware and software of the device other than supporting Wi-Fi. Focus is on designing a scalable system capable of positioning devices on multiple sites. The suggested solution uses commercially available Wi-Fi access points to observe the received signal strength when a device probes for nearby access points. The information gathered by the access points is forwarded to a

Abstract:

A technique is proposed to improve the accuracy of indoor positioning systems based on WIFI radio-frequency signals by using dynamic access points and fingerprints (DAFs). Moreover, an indoor position system that relies solely in DAFs is proposed. The walking pattern of indoor users is classified as dynamic or static for indoor positioning purposes. I demonstrate that the performance of a conventional indoor positioning system that uses static fingerprints can be enhanced by considering dynamic fingerprints and access points. The accuracy of the system is evaluated using four positioning algor

The principal objectives of this research are: to investigate the performance of different fingerprint-based WiFi Indoor Positioning Systems (IPS), analyse historical long-term data signals, detection of signal change points and outliers; then present an enhanced method that generates temporal based fingerprints. The proposed method consists of analysing signal strength profiles over time and detecting points at which the profile behaviour changes. This methodology can be used to dynamically adjust the fingerprint based on environmental factors, and with this select the relevant Wireless Acces

This thesis presents a prototype beacon-based indoor positioning system using IR-based triangulation together with various inertial sensors mounted onto the receiver.

Abstract:

Indoor positioning systems can be of a great help when trying to local- ize in an indoor environment. To be able to navigate, there is a need for an indoor map that to some degree represent the reality. This thesis aims to come up with a proof of concept of a system that maps rectan- gular objects onto a two dimensional map in an indoor environment. The maps will be drawn with the help of the position of a hand-held device that marks the corners of the objects. A problem that arises is that the error in the positioning can contribute to objects that have the same size and are aligned in realit

Abstract:

There is a high demand for Indoor Positioning Systems (IPS) due to the wide application possibilities. The main issue for localization by wireless signals in an indoor environment is the multipath propagation problem. Multipath propagation occurs when signals reflects and refract from an object, changing the signals characteristics. Today there is no IPS that can balance the cost, accuracy, and complexity. In January 2019 Bluetooth released a new standard, Bluetooth Low Energy (BLE) 5.1, which enables the ability to measure the Angle of Arrival (AoA) of an incoming signal. The purpose of this

Abstract:

RF fingerprinting can solve the indoor positioning problem with satisfactory accuracy, but the methodology depends on the so-called radio map calibrated in the offline phase via manual site-survey, which is costly, time-consuming and somewhat error-prone. It also assumes the RF fingerprint’s signal-spatial correlations to remain static throughout the online positioning phase, which generally does not hold in practice. This is because indoor environments constantly experience dynamic changes, causing the radio signal strengths to fluctuate over time, which weakens the signal-spatial correlation

In this paper, a new concept for ultrasonic indoor positioning based on instantaneous frequency of ultrasonic signals is presented. Nonlinear phase characteristics of ultrasonic transducers introduce a frequency deviation in ultrasonic signals. By sweeping at very fast rates, a large spike in the deviation is introduced. The artefacts observable in instantaneous frequency estimations are highly localized and present an opportunity for accurate frequency detection. In order to be useful, the artefacts need to take place within the pulse and have sufficient magnitude for accurate processing. The

Currently, indoor positioning system has difficulty to give a 100% of positioning because of environmental influences including pedestrian, WiFi etc.. It becomes crucial to increase the positioning accuracy, especially on dynamic environment. In this study, a wireless network system consisted of XBEE sensors, arduino and raspberry pi is constructed as a new positioning system. The XBEE sensors are used to collect the RSSI signal strength from the wir

However, in view of the fact that GPS signal lacks of accuracy and can not reach the interior of the construction, this research focuses on the development of indoor mobile augmented reality position tracking system. Taking high environmental adaptability, and high system maintainability as goals, we devoted to realize precise line of sight tracking technique for indoor AR position tracking service

碩士<br>國立中興大學<br>通訊工程研究所<br>100<br>In recent years, the sensor units of the wireless sensor network have made tremendous progress, and it has been used in a wide variety of applications. Indoor positioning system is the important one of those applications. The most well-known positioning system is GPS (global positioning system). GPS has been researched and developed for many years, and provides great accuracy in the location system. However, GPS not only requires a LOS (line of sight) to satellite, but it also needs high cost to implement the system. As the result, we cannot implement GPS for

Any wireless related technology which can achieve positioning can be adapted. With Wi-Fi solution becomes ubiquitous it is a vital technology to support, in our day-to-day life. In fact, we are covered by many Wi-Fi signals wherever we are. Along with it being a built-in feature on modern smartphones, therefore Wi-Fi technology is the most commonly obtainable wireless technology. This thesis proposes to use the Power Level (PL) in Wi-Fi Access Point (AP) to s

Abstract:

The advancements of the indoor positioning system (IPS) in the recent years have been immense, yet we do not see the standardization of any solution. The system which is being used in many public scenarios is the Wi-Fi technology and the solution which we propose in this dissertation would not require change of infrastructure, but rather reusing existing one and simply enhancing it. This solution is low-cost and with relatively high precision considering current precision of Global Positioning System (GPS) of five meters. In this dissertation prototype is designed with motorized directional an
