Projector camera cooperation
Walter, Viktor ; Horák, Karel (referee) ; Richter, Miloslav (advisor)
The focus of this thesis is the cooperation of cameras and projectors in projection of data into a scene. It describes the means and theory necessary to achieve such cooperation, and suggests tasks for demonstration. A part of this project is also a program capable of using a camera and a projector to obtain necessary parameters of these devices. The program can demonstrate the quality of this calibration by projecting a pattern onto an object according to its current pose, as well as reconstruct the shape of an object with structured light. The thesis also describes some challenges and observations from development and testing of the program.

3D scanner for educational purposes
Romanovský, Jiří ; Navrátil, Robert (referee) ; Koutecký, Tomáš (advisor)
This diploma thesis deals with the design of a 3D optical scanner using the structured light projection method. The aim of this thesis is to demonstrate the principles and processes of 3D scanning by using the DLP LightCrafter projector and the ImagingSource camera. The individual stages of the measurement process will be implemented to the Matlab software environment to describe the various principles and methods which can be used for digitizing the objects.

Creating a 3D Face Model Using Kinect Device
Nesvadba, Tomáš ; Malinka, Kamil (referee) ; Mráček, Štěpán (advisor)
The main aim of this bachelor's thesis is to suggest a method for increasing the resolution of 3D face models captured by Kinect. The document describes different methods of capturing 3D models and compares the Kinect sensor with more acurate scanners. The main part of this document is dedicated to statistic model based on the PCA and its usage in the project. The last section of the paper describes testing of various models and discuss the results and another options of aplication.

Structured-light 3D scanner
Hadzima, Jaroslav ; Chromý, Adam (referee) ; Jelínek, Aleš (advisor)
3D scanner is a device capable of creating a model using analysis, most commonly from image data. 3D scanners could be divided into two major groups, contact and noncontact scanners. Aim of this study is to interpret problematics of 3D scanning with structured light. Specifically usage of Gray code patterns. There is step by step evaluation of individual hardware and software obstacles and possible errors, from calibration to final point cloud. In next section, there are included tests determining quality, precision and accuracy of scanning with given method. System is applicable to mobile robots and yet fully remotely controlled. The majority of enumerations is taking place in Raspberry Pi 3 model B, just visualization alone is done from computer.

Realization of a structured light 3D scanner
Přikryl, Matouš ; Brablc, Martin (referee) ; Adámek, Roman (advisor)
The beginning of the thesis presents 3D scanner types. Following part describes how the structured light 3D scanners works. It takes into the account whole scanning process and adress problems like calibration, optical triangulation, or surface reconstruction of 3D objects. The second half of the thesis is focused on the implementation of simple 3D scanner, using Machatronics laboratory hardware. It also describes scanners behaviour in different conditions.

3D scanning methods
Čermák, Jan ; Matyáš, Pavel (referee) ; Marada, Tomáš (advisor)
In the first part of this thesis there is a task of taxonomy of the 3D scanners. It explains some principles of the 3D scanners functioning. Then in the second part there are described two particular technologies of the 3D scanning in the more complex way. In the chapters of both of these methods there is described procedure of scanning and compared several commercially available sensors. In the end there is comparison of these two methods.

3D dental scanner
Kotek, Lukáš ; Sekora, Jiří (referee) ; Balogh, Jaroslav (advisor)
The general aim of my master´s thesis is to study the actual principles of 3D scanning, the anatomy of human teeth, use of 3D scanning in dentistry and other medical fields. Another part of this thesis is about software and hardware design of 3D scanning system, which enable us to scan dental casts. This design is using webcam, projector and turntable. The principle of scanning is based on the activ triangulation. The output of 3D scanner is a horde of spots, which are used for reconstruction of a surface. The reconstructed surface is finally saved as .stl format.

Depth map by using Kinect
Němec, Pavel ; Kaller, Ondřej (referee) ; Boleček, Libor (advisor)
Nowadays, depth maps are widely used in various branches of human activity (in building industry, medicine, mechanical engineering, robotics, show business etc.). The aim of this thesis is to get acquainted with different methods of their acquisition and with possibilities of their enhancement (e.g. reduction of noise and points of not specified depth). The main subject of this research are depth maps acquired by Kinect device.

WWW tutorial for HP 3D scanner Pro S3
MOJŽÍŠOVÁ, Denisa
In the first part, this work deals with the basic concepts and principles of operation of 3D scanning technology, there are analysed the various types of 3D scanners. The hardware and software of the HP 3D scanner Pro S3 are also discussed. In the second part, the hardware connection and setting of basic software parameters is analysed in detail, which is supplemented by sample tasks. In the end, the findings that were recorded during the work are summarized.
