USE OF AUTOMATIC COLLECTION OF GROUND CONTROL POINTS FOR ORIENTATION OF ARCHIVAL AERIAL IMAGERY USING EXISTING DATA SETS
Berka, Rostislav ; Potůčková, Markéta (advisor) ; Dušánek, Petr (referee)
USE OF AUTOMATIC COLLECTION OF GROUND CONTROL POINTS FOR ORIENTATION OF ARCHIVAL AERIAL IMAGERY USING EXISTING DATA SETS Abstract The diploma thesis is focused on the automated searching of ground control points (GCPs) for processing archival aerial images (AAIs) and creating orthomosaics. The study evaluates selected computer vision operators (SIFT, SURF, ORB and image correlation) and various approaches for identifying and subsequently matching identical points between the reference dataset (current orthophoto) and AAIs. Thanks to AAIs georeferences, the searching area in AAI is known for finding the corresponding point to the reference one (from current orthophoto). Unfortunately, the georeferencing of AAIs provided by the Czech Office for Surveying, Mapping, and Cadastre (ČÚZK) was methodologically incorrect (very bad accuracy) and it had to be corrected before automated GCPs searching. The topic was supported by ČÚZK and datasets (current orthophoto, AAIs, ZABAGED vector data) were provided for processing purposes free of charge (beyond the standard student license). Based on operator testing, a fully automated methodology was developed in Python, relying on image correlation. The input includes AAIs, current orthophoto and a road network, with road intersections as reliable and time invariant points....

Automatic Construction of a Terrain Map by a Drone
Kapsa, Jan ; Bambušek, Daniel (referee) ; Beran, Vítězslav (advisor)
This thesis focuses on how UAV mapping functions with the focus on methods working in real-time. The process of image stitching is thoroughly explained and 2 methods based on it are designed. Together with these methods dataset is built containing different situations. Maps of the terrain are created by these methods, which are then compared and scored.

Edge detection and representation in point clouds
Večeřová, Alena ; Druckmüllerová, Hana (referee) ; Procházková, Jana (advisor)
This thesis discusses edge detection and representation in point clouds. For the detection of edge points was used clustering of normals. The RANSAC method is used to represent the line edges. Within the work, the edge points of one model are also interspersed with a circle using the least squares method and projective space. All methods were implemented in MATLAB and tested on real data obtained on the ATOS CompactScan 2M scanner.

Augmented Reality in Industrial Production and Maintenance
Kajan, Matej ; Janáková, Ilona (referee) ; Horák, Karel (advisor)
This paper seeks to explore the possibility to utilize XR (extended reality) in industrial assembly. The aim is to implement a system, which is able to visually navigate the operator during the product assembly process by the means of object recognition and image augmentation. The first chapter presents the use-case of augmented reality in the industry. The next part consists of research on the topic of augmented and virtual reality devices and provides a brief comparison of the current state of the art. Afterwards, a methodology is presented for object recognition of an arbitrary object. The implementation is able to detect the object in real-time, is resilient to occlusion and contains the information about the object’s orientation.

Replacement of QR Codes by Colored Matrices
Moc, Filip ; Szentandrási, István (referee) ; Herout, Adam (advisor)
This bachelor's thesis is about developing new color code for saving digital data in an image. In this report you can find informations about existing related technologies including some existing codes. You can also find here design of the new code and it's gradual improvements. There is also description of generation and recognition of this code. Finally there are results of experiments which demonstrates the success of all the work.

Microdots scanner
Červinka, Luděk ; Honec, Peter (referee) ; Horák, Karel (advisor)
The microdots are very small object. The microdots are applied in protection object. The project purpose is to find and to analyze the microdots. The project consists from two parts. A first part describes the hardware sensor construction and a second part describes the software solution. I selected the optics, camera module and illumination in the hardware part. I’m analyzing of the microdots on a picture in software part.

Point cloud clustering
Mrkvička, Daniel ; Štarha, Pavel (referee) ; Procházková, Jana (advisor)
This bachelor's thesis deals with the point cloud clustering. It focuses on surface detection in three-dimensional space. It describes in particular the methods that are used for plane detection. It also describes the concrete implementation of one of these method, the RANSAC, and examines its practical application for roof detection.

Panoramatic View Reconstruction
Kuzdas, Oldřich ; Kohoutek, Michal (referee) ; Říha, Kamil (advisor)
This paper deals step by step with process of stitching images taken by perspective camera rotated by its optical center into the panoramic image. There are described keypoint searching algorhytms, possibilities of calculating homography matrix and methods of eliminating unwanted seams between source images in final panoramic image. A part of this paper is also standalone application in which are implemented some algorhytms described in the work.

Mobile Robot Localization in an Appartment Using Mono-Camera
Konderla, Tomasz ; Veľas, Martin (referee) ; Beran, Vítězslav (advisor)
This bachelor is thesis deals with the localization of the robot by means of image analysis from the camera placed on the robot. I will also deal with the formation of a 3D model of the environment which is created of a data set of photos taken with the camera. The 3D model I will create using the method of SFM. I will locate the camera using the pre-set 3D model. In my bachelor is thesis I will further describe the theory of processing of the image data necessary for this project. Finally, I will evaluate the results of the success of the localization.
