Visualization Environment for Robot Remote Control
Blahož, Vladimír ; Polok, Lukáš (referee) ; Španěl, Michal (advisor)
This thesis presents possibilities of 3D point cloud and true colored digital video fusion that can be used in the process of robot teleoperation. Advantages of a 3D environment visualization combining more than one sensor data, tools to facilitate such data fusion, as well as two alternative practical implementations of combined data visualization are discussed. First proposed alternative estimates view frustum of the robot's camera and maps real colored video to a semi-transparent polygon placed in the view frustum. The second option is a direct coloring of the point cloud data creating a colored point cloud representing color as well as depth information about an environment.

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.

Object Detection Using Kinect
Švec, Ján ; Zahrádka, Jiří (referee) ; Španěl, Michal (advisor)
This bachelor's thesis deals with the object detection using Kinect. Kinect is a motion sensing input device by Microsoft company for the Xbox 360 video game console. The objective of this work was to evaluate the existing approaches and practices for the detection not only using the image from the camera but also depth map (RGB-D sensor). The work deals in details with RoboEarth tool, its installation, settings, creation of 3D model and the detection. Performance of the RoboEarth tool was in the work investigated experimentally and also evaluated.

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.

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.
