Photogrammetric Image Analysis
Velebová, Jana ; Španěl, Michal (referee) ; Zemčík, Pavel (advisor)
This thesis is dedicated photogrammetric image analysis that makes it possible from your photos with the help selected methods to determine the location and dimensions of objects recorded on them. There are explained the basics of photogrammetry and its current application. Chapters focused on digital imaging describing its characteristics, treatment options and key points findability for the scene calibration. For a comprehensive view are in this thesis introduced examples of existing software, its possibilities and use in practice.

Camera cover design for industrial environment
Knoth, Tomáš ; Koutecký, Tomáš (referee) ; Hurník, Jakub (advisor)
This bachelor’s thesis deals with the design of a camera housing for industrial environment. In opposite to the solutions available on the market, the designed housing is adapted to a specific measuring application, which in addition to common parameters such as thermoregulatory properties and degree of protection requires weight reduction, camera mounting stiffness, optical parameters of the window and easy maintenance of the housing. The required properties of the newly designed housing were achieved, among other measures, by minimizing the volume of steel and applying an insulation material. The resulting design has about 47 % lower heat gain and its weight is 69 % lower compared to the housings now used in this specific application. This housing will help enhance the properties of a photogrammetric system for measuring of forgings which is being developed at the Institute of Machine and Industrial Design, FME BUT.

Processing of images taken from UAV
Roubal, Pavel ; Plánka, Ladislav (referee) ; Hanzl, Vlastimil (advisor)
The aim of the thesis was to process the images taken by UAS technology and especially to test the accuracy of this method on the checkpoints of various types. For this testing were used checkpoints that were measured by geodetic method. Subsequently these points were compared with points measured photogrammetrically.

Use of photogrammetry expertise in the field of construction and real estate valuation
Slabotinský, Filip ; Klika, Pavel (referee) ; Daňhel, Petr (advisor)
The task of this diploma thesis is to design and test the optimal procedures for taking photos to build a 3D model of a civic building using the programme PHOTOMODELER. Then to determine the specific dimensions of the civic building and compare them with the dimensions received with the help of the basic method of measurement in common building practice, i.e. the method of cross directions (using a tape or a telescopic measuring rod) and the geodetic method of measurement. After that to evaluate these measurements and make the conclusion concerning the accuracy or inaccuracy of measurements received with the help of the 3D model of the compiled programme PHOTOMODELER.

Photogrammetric data storage
Malásek, Jan ; Petyovský, Petr (referee) ; Babinec, Tomáš (advisor)
The Bachelor´s thesis gives us a view of computer vision development and its applications in a real world. It exists many typical tasks of computer vision. This thesis is focused on the scene description of picture information. It describes the most widely used types of relational databases, their advantages and disadvantages. The most important part of the work is a realization of application for photogrammetric data service. It is programmed in C# using Microsoft Visual Studio 2010. The application is based on a relational database system Microsoft SQL Server Compact Edition 3.5.

Evaluation of data captured by UAV
Martináková, Veronika ; Setnický, Viktor (referee) ; Kalvoda, Petr (advisor)
The master´s thesis deals with the application of unmanned aerial vehicle (UAV) in photogrammetry and mapping. The first part describes the UAV that was used for imaging, legislative restrictions resulting from its operations, planning and realization of the flight. The second part of this thesis is focused on processing results, especially on evaluation the accuracy of the results gained by UAV with and without a GNSS module. The data are evaluated in the 3rd accuracy rating class (ČSN 01 3410). The theoretical principles are explained as well. The main aim of the thesis is to demonstrate the effective use of the GNSS module Emlid Reach and the unmanned aerial vehicle in geodesy.

Comparison of methods of 3D model
Balák, Martin ; Bartoněk, Dalibor (referee) ; Hanzl, Vlastimil (advisor)
This bachelor thesis is about 3D modelling by using different methods and different types of processing. It describes the process of creating a model in Photomodeler software and Autodesk 123D – Catch software. A major part of the thesis focuses on comparing accuracy of the photogrammetric evaluation. Another factor used to compare the different techniques is how time – consuming it is. The final chapter is devoted to the overall evaluation of the techniques.

3D data processing
Babinec, Tomáš ; Janáková, Ilona (referee) ; Richter, Miloslav (advisor)
The thesis falls within the field of computer vision. It describes the development of the software environment for 3D data processing. The thesis deals with the design of C++ classes suitable for scene description and representation of bonding conditions between scenes elements. There is also discussed the solution of camera calibration, geometric distortion identification and 3D coordinates reconstruction. The solving of these tasks is augmented with planarity and linearity conditions, which support projection equations and augment the computational ability of the environment.
