Speed Measurement of Vehicles from Surveillance Camera
Jaklovský, Samuel ; Juránek, Roman (referee) ; Sochor, Jakub (advisor)
This master's thesis is focused on fully automatic calibration of traffic surveillance camera, which is used for speed measurement of passing vehicles. Thesis contains and describes theoretical information and algorithms related to this issue. Based on this information and algorithms, a comprehensive system design for automatic calibration and speed measurement was built. The proposed system has been successfully implemented. The implemented system is optimized to process the smallest portion of the video input for the automatic calibration of the camera. Calibration parameters are obtained after processing only two and half minutes of input video. The accuracy of the implemented system was evaluated on the dataset BrnoCompSpeed. The speed measurement error using the automatic calibration system is 8.15 km/h. The error is mainly caused by inaccurate scale acquisition, and when it is replaced by manually obtained scale, the error is reduced to 2.45 km/h. The speed measuring system itself has an error of only 1.62 km/h (evaluated using manual calibration parameters).

Radar-Based Speed Measurement for Sport Events
Radoš, Daniel ; Polok, Lukáš (referee) ; Maršík, Lukáš (advisor)
The Bachelor thesis is dedicated to speed measurement focused on sport events. In introduction of this thesis, basic principles of radar and their dividing are mentioned. Following part of thesis is dedicated to continuous wave radar, using Doppler effect and also principle of sequential signal processing, followed by resultant speed calculation of measured object. Ultimately, selected methods are implemented and tested using real data. In the end, the implemented application is evaluated and the possible continuation of this work is stated.

Radar sensors for speed measurements
Doležal, Tomáš ; PhD, Jaroslav Čechák, (referee) ; Kokolia, Martin (advisor)
The main topic of this bachelor thesis is selecting a suitable microwave sensor for measuring the speed of vehicles in regular traffic, while covering multiple road lanes by a suitable method. Furthermore, the optimal one is selected in the form of search, based on the necessary parameters from commercially available radar sensors measuring primary speed. In the next step, simulation is performed for the selected speed sensor in the MATLAB environment, depending on its parameters and the modes in which it can work. The simulation also includes environmental influences on the received signal. There is introduced programmed graphical user interface for simulating a lot of situations on the road for two cars in the next section. Last section summarizes results of real measurement.

Speed Measurement Using Radar
Martinů, Lukáš ; Široký, Vít (referee) ; Maršík, Lukáš (advisor)
Bachelor's thesis is focused on method of object's speed detection using a low-cost continuous wave radar module. In the first section, it describes differences between basic types of radar modules and their fundamental principles. The main part of thesis is dedicated to signal processing of radar modules K-MC1, K-MC4, that contents data to analyze moving objects. Doppler effect is used to determine the object's relative speed. Moreover, there is used FSK technique to measure the distance and there are solved issues associated with cosine factor. To verify the performance and stability, the application is tested on a several appropriate objects. In the end, the implemented application is evaluated and the possible continuation of this work is stated.

Rules designing roads for skaters
Skalická, Petra ; Bačová,, Katarína (referee) ; Kocourek,, Josef (referee) ; Radimský, Michal (advisor)
The dissertation deals with non-motorized transport. Specifically, it focuses directly on the new non-motorized traffic sector, which is the riders of roller skates. Title of the dissertation The rules for designing roads for skaters were selected from the point of view of unresolved issues. The main goal of the dissertation is to enable the legislative inclusion of skaters as a separate group into the transport hierarchy so that they can gain space for their movement in the transport area. The result should be primarily a reduction in accidents and an increase in road safety for non-motorized vehicles. Other objectives of the thesis include the creation of design parameter tables for methodological instructions based on the analysis of the data obtained by measuring and determining the critical traffic intensity on existing roads. The dissertation summarizes the current issue of non-motorized transport, but especially the issue of skaters transport. It assesses the situation in the Czech Republic compared to the conditions abroad. It explains the physical patterns of the skater's movements, based on which the spatial demands on the used transport space are derived. The following is an overview of selected methods dealing with measurement and evaluation of transport speeds and intensities. Depending on the values found, rules are then created for designing the basic parameters of the skateboard trail network, which includes, for example, traffic sign design and construction requirements.

Stroboscope tachometers
Hortai, František ; Vágner, Martin (referee) ; Beneš, Petr (advisor)
This bachelor’s thesis describes the design of a rotation measuring device using stroboscopic effect. In the first part of my work I have studied the solutions to the problems of rotation measuring, followed by description of the stroboscopic effect. Individual chapter presents a market research of the commercial strobe tachometers. The practical part proposes and designs an own stroboscope. The stroboscope allows manual adjustment, external synchronization, phase shifting. Electronics is controlled by a microcontroller from Atmel, the light source are power LEDs. It was designed a two-sided circuit board by using Eagle Professional 6.1.0. The circuit board was brought to function by planting the components on it. Development continued by creating the driving program for the microcontroller. The end result of my work is functional stroboscopic tachometer in a box together with the necessary electronic components serving for its proper functioning.

Ensuring Precision of Stereo Image Processing
Kuník, Oliver ; Španěl, Michal (referee) ; Zemčík, Pavel (advisor)
This thesis deals with the possibilities of refining the results of stereo image processing and examines the methods of stereo image stabilization. Proposes a method of stabilizing the stereo recording with respect to the designated reference stereo image to keep the images in the calibration position of the camera. An affine transformation is used to eliminate the movement of stereo images. The positions of the corner points found with subpixel precision are used for calculating the transformation. This thesis includes a comparison of the stabilization efficiency of a stereo record intended for vehicle speed measurements.
