3D Face Reconstruction
Poulíček, Zbyněk ; Šiler, Ondřej (referee) ; Španěl, Michal (advisor)
The top of this thesis is 3D face reconstruction by the help the projected regular grid from the 2D image. It also includes the grid detection and the description of methods that are needed to raster image processing. The application was written in C++ programming language, it uses OpenCV graphic library, and also it is designed for OS Windows XP and higher.

Automatic Processing of Recordings from In-Car Camera
Klos, Dominik ; Herout, Adam (referee) ; Španěl, Michal (advisor)
This thesis deals with the automatic processing of recordings from in-car camera, which is used for estimating distances in a scene filmed. To achieve this goal, it uses the methods of image processing, spatial geometry of the scene and 3D reconstruction, whose final output is a partial model. For this aim, the Bundler tool is used. Results of reconstruction are visualized in the application, which then allows to estimate the distance of objects from the camera or the distance between each other.

3D Scene Reconstruction from Images
Ambrož, Ondřej ; Řezníček, Ivo (referee) ; Španěl, Michal (advisor)
Existing systems of scene reconstruction and theorethical basics necessary for scene reconstruction from images data are described in this work. System of scene reconstruction from video was designed and implemented. Its results were analyzed and possible future work was proposed. OpenCV, ArtToolKit and SIFT libraries which were used in this project are also described.

3D Model Reconstruction and Camera Localization
Vahalík, Tomáš ; Materna, Zdeněk (referee) ; Beran, Vítězslav (advisor)
This thesis focuses on reconstruction of 3D environment model from a set of photographs followed by camera localization. It describes basic principles and techniques used to create environmental models and techniques for camera pose estimation from 2D camera points to 3D model points. It also examines the influence of parameters on the quality of reconstruction and the possibilities of localization. It compares the quality of the descriptors in the process of creation of the model and based on localization it allows to implement augmented reality.

Stereoscopic Navigation of a Robot
Žižka, Pavel ; Šolony, Marek (referee) ; Žák, Pavel (advisor)
This work describes 3D reconstruction using stereo vision. It presents methods for automatic localization of corresponding points in both images and their reprojection into 3D space. Application created can be used for navigation of a robot and object avoidance. Second part of the document describes chosen components of the robot. Path finding algorithms are also discussed, particulary Voronoi's diagram.

3D microstructure evaluation of developed Si3N4 material for alloyed wire rolling applications
Lövy, Vít ; Salamon, David (referee) ; Chlup, Zdeněk (advisor)
This diploma thesis is devoted to the use of 3D reconstruction using EBSD method for microstructural analysis of silicon nitride ceramic material predetermined for the rolling-mill used in the wire production. Application of this method can be used for the grain structure reconstruction and basic microstructural parameters can be than extracted. The development of a suitable method for 3D reconstruction of the structure of the materials the main aim of this work. There are described the different steps begun by sample preparation from the investigated material trough the optimisation of analysis parameters up to the visualization of the grain structure. New type of sample geometry has been designed which leads to the better and faster observation of the microstructure of ceramic materials. This thesis also describes optimal reconstruction parameters such as the geometry of the assembly used in the microscope without mechanical movement of the sample or the influence of conductive coating prepared via in-situ sputtering of suitable metal, or adjustment of the electron and ion beams. Further are described two options of software which can be used for the final generation of 3D structure information and are assessed their advantages and disadvantages. The effect of the filter setting and other parameters and their influence on the resulting structural parameters are also evaluated.

3D reconstruction
Musálek, Martin ; Horák, Karel (referee) ; Richter, Miloslav (advisor)
Thesis solves 3D reconstruction of an object by method of lighting by pattern. A projector lights the measured object by defined pattern and two cameras are measuring 2D points from it. The pedestal of obejct rotates and during the measure are acquired data from different angles. Points are indentified from measured images, transformed to 3D using stereovision, connected to 3D model and displayed.

Stereo image processing and visualisation
Karásek, Miroslav ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
This thesis deals with the processing of stereo images. It described the principles of calibration and rectification of stereo images. The thesis described several methods for finding important points. SURF method is then implemented for practical solution. Finding correspondences is realized using the methods of image processing library OpenCV. Reconstructed spatial coordinates of points and write by the format specified VRML97. Finally, there is introduced evaluated accuracy of spatial data acquisition and comparison of computational cost generated programs.

Online 3D reconstruction
Bastl, Jiří ; Horák, Karel (referee) ; Petyovský, Petr (advisor)
This thesis describes reconstruction of scene which is scan trough two cameras. There are described methods of calibration of cameras system, methods for finding the corners and methods for finding correspondences. Corners are searched by FAST detector and for search correspondences are used normalized cross correlation. In the framework of 3D reconstruction is implemented rectification. The final shape is saved to VRML format. In the thesis are described parallelization options. The calculation of the correlation is optimized for multiprocessors CPU and there are designed implementations of algorithm to GPU and FPGA too.
