3D Scene Reconstruction from Images
Fuchsík, Ondřej ; Zahrádka, Jiří (referee) ; Španěl, Michal (advisor)
This bachelor thesis deals with scene reconstruction from images using RGB--D senzo Microsoft Kinect. The aim of the work is to create model of the room in form of points from scanned data, from witch is created plan of the interior. A large part of the work deals with the point cloud registration, thus existing methods and their descriptions. Further, a projection of points on a plane and detection of edges in the obtained image are discussed. The work experimentally examines the influence of recording and the recorded environment on results.

3D Scene Reconstruction from Images
Hejl, Zdeněk ; Kršek, Přemysl (referee) ; Španěl, Michal (advisor)
This thesis describes methods of reconstruction of 3D scenes from photographs and videos using the Structure from motion approach. A new software capable of automatic reconstruction of point clouds and polygonal models from common images and videos was implemented based on these methods. The software uses variety of existing and custom solutions and clearly links them into one easily executable application. The reconstruction consists of feature point detection, pairwise matching, Bundle adjustment, stereoscopic algorithms and polygon model creation from point cloud using PCL library. Program is based on Bundler and PMVS. Poisson surface reconstruction algorithm, as well as simple triangulation and own reconstruction method based on plane segmentation were used for polygonal model creation.

Object Detection Using Kinect
Němec, Lukáš ; Veľas, Martin (referee) ; Španěl, Michal (advisor)
This paper address the problem of object recognition using Microsoft Kinect in the fi eld of computer vision. The objective of this work was to evaluate current methods of detection of objects using depth map (RGB-D sensor). The work deals with the enviroment of point cloud and Viewpoint Feature method. It also describes the use of binary classifi er in the context of object recognition. Object detection was implemented and performed experiments with it.

Tabletop Object Detection
Varga, Tomáš ; Zemčík, Pavel (referee) ; Španěl, Michal (advisor)
This work describes the issue of tabletop object detection in point cloud. Point cloud is recorded with Kinect sensor. Designed solution uses algorithm RANSAC for plane detection, algorithm Euclidean clustering for segmentation and ICP algorithm for object detection. Algorithm ICP is modified and mainly it can detect rotational symetric objects and objects without any transformation against it's models. The final package is build on platform ROS. The achieved results with own dataset are good despite of the limited functionality of the detector.

The Use of Photogrammetry in the Real Estate Practice
Viktora, Jakub ; Daňhel, Petr (referee) ; Klika, Pavel (advisor)
This diploma thesis aims to explore possibilities of using IT in real estate and projection practice. It deals with simplification of difficult or insolvable tasks. It focuses on rapidly developing field of photogrammetry and its further processing via software. The work presents methods of measurement of existing realties without using standard methods (tape line, laser). Instead of these tools, the author uses photographic data and program PhotoModeler for surveying and creating a 3D model of the facade. The thesis verifies further serviceability of gained data up to the render phase of the surveyed building facade.

Processing of images taken from UAV
Ptáček, Ondřej ; Plánka, Ladislav (referee) ; Hanzl, Vlastimil (advisor)
This diploma thesis deals with the processing and evaluation of the pictures taken by unmanned aerial vehicles - UAV. The introductory part is devoted to the definition, use, applications and types of UAV especially for photogrammetric purposes. Also the software equipment is described, including a description and examples of several types of possible outcomes. Further the measurements, computational works and process of elaboration in used software programs are described. Achieved outcomes of elaboration are also presented. In conclusion, the overall evaluation and assessment of the results of measurement is done of set of points.

Static analysis of bell stool using modern geodetic methods
Mojrová, Martina ; Vlk, Zbyněk (referee) ; Nevařil, Aleš (advisor)
The aim is to create a static model assessment of construction bell stools using new geodetic methods. This means data processing from laser scanner called. Point Cloud to the geometric model, which can be imported into a variety of drawing and modeling programs. Furthermore, use this geometrical model to create a static model, in program ANSYS FEM model and then calculate the internal forces. Finally, assessment of structures according to EN 1995-1 Design of timber structures.
