Abstract:
Scanning är ett verktyg som har utvecklats mycket och används mer och mer inom geodetisk mätning. Instrumenten har blivit mer pålitliga med högre kvalité på resultaten, därför är det viktigt att eliminera de problem som kan skada scanningens pålitlighet. Det problemet som ska undersökas och testas i det här examensarbetet uppstår när man till exempel scannar en bergvägg. Man vill få en så lik avbildning av bergväggen som möjligt för att sedan kunna göra volymberäkningar emot bergväggen. Avbildningen av bergväggen består av ett moln av punkter som tillsammans skapar en 3D-modell av bergväggen.

Abstract:
Many practical tasks in industry, such as automatic inspection or robot vision, often require scanning of three-dimensional shapes with non-contact techniques. However, transparent objects, such as those made of glass, still pose difficulties for classical scanning techniques. The reconstruction of surface geometry for transparent objects is complicated by the fact that light is transmitted through, refracted and in some cases reflected by the surface. Current approaches can only deal relatively well with sub-classes of objects. The algorithms are still very specific and not generally applicab

Abstract:
In this thesis project, an underwater 3D scanner based on structured light has been constructed and developed. Two other scanners, based on stereoscopy and a line-swept laser, were also tested. The target application is to examine objects inside the water filled reactor vessel of nuclear power plants. Structured light systems (SLS) use a projector to illuminate the surface of the scanned object, and a camera to capture the surfaces' reflection. By projecting a series of specific line-patterns, the pixel columns of the digital projector can be identified off the scanned surface. 3D points can t

<p>This report summarizes the work done to develop a 3D teleconferencing system, which enables remote participants anywhere in the world to be scanned in 3D, transmitted and displayed on a constructed 3D display with correct vertical and horizontal parallax, correct eye contact and eye gaze. The main focus of this report is the development of this system and especially how to in an efficient and general manner render to the novel 3D display. The 3D display is built out of modified commodity hardware and show a 3D scene for observers in up to 360 degrees around it and all heights. The result is a

Abstract:
The initial geographic information system (GIS) and building information modelling (BIM) are designed and developed independently in order to serve different purposes and use. Within the prolific increase and growing maturity of three-dimensional (3D) technology, both 3D geodata and BIM data can specify semantic data and model 3D buildings that are prominent for the 3D city models and 3D cadastre. 3D geodata can be collected from geodetic surveying methods such as total station, laser scanning and photogrammetry and generate 3D building models by CityGML format for macro analysis on city scale

Abstract:
The aim of the submitted semestral project is research of 3D scanning object methods. The 3D scans utilization and types of these scans have been mentioned in the first chapter. The scanners are grouped into two basic methods – contact and contactless. The second chapter is dedicated to 3D model measurement principles, which are described in detail in four sub-chapters. In the following chapter is described design with complete realization 3D scanner with the implementation of the application for its controlling. Last part of the thesis concerns the 3D model editing and method evaluating.

Abstract:
Photogrammetric software today is at a level where it is accessible to the mainstream public and without larger effort is able to reconstruct digital 3D models from photographic input.  This thesis investigates the performance of photogrammetricly reconstructed models and evaluates them by comparing the results to their corresponding reconstructed models from a 3D laser scanner with a focus on smaller objects in an amateur environment. The evaluation is performed on four different objects, which are all individually compared to their scanned counterpart. They are compared both with a subjectiv

碩士<br>義守大學<br>生物醫學工程學系<br>107<br>In recent years, the application of 3D scanning technology in human body has attracted much attention. Because the traditional impression is cumbersome and time consuming, the study tried to improve the effectiveness of the dental impression by using the different 3D scanning techniques. The study first compared different 3D scanning algorithms and used the block gauges for verification, and then scanned the tooth models of different materials and sizes for comparative evaluation. The three scanning methods used in this study include: "Gray Code Algorithm", "Hy

碩士<br>國立臺灣科技大學<br>色彩與照明科技研究所<br>104<br>Nowadays, the judgment of the 3D reconstructed object is generally cared about accuracy of the shape, but the quality of the face color is often neglected in 3D scanning field. The color information is one of the most important factors for people while evaluating the object. The face color comes from the recorded 3D texture images while 3D reconstructing. Therefore, this thesis focuses on solving the problem of the color information of the 3D texture images, and correcting the face color further. There are two experiments in this thesis. One is defined as

Abstract:
Dissertação de mestrado em Engenharia de Informática<br>Computer vision is usually used as the perception channel of robotic platforms. These platforms must be able of visually scanning the environment to detect specific targets and obstacles. Part of detecting obstacles is knowing their relative distance to robot. In this work different ways of detecting the distance of an object are analyzed and implemented. Extracting this depth perception from a scene involves three different steps: finding features in an image, finding those same features in another image and calculate the features’

Abstract:
Obtaining geometrical and physical information of industrially manufactured products or manually created artifacts has increased dramatically in the past few years. These data are usually generated by means of specific devices which are called 3D scanners. 3D scanners generate virtual 3D models of objects which in different fields can be used for various applications such as reverse engineering and quality control in manufacturing industry or data archiving of valuable unique objects of cultural heritage. There are basically two types of 3D scanning depending on whether contact or non-contact
