Indoor localization based on UWB technology
Bauer, Jan Jiří ; Vyroubal, Petr (referee) ; Čech, Ondřej (advisor)
This bachelor thesis is exploring ways to localize an object in space, primarily using UWB technology. Diverse ways to determine distance (TWR, RSSI, TDoA), location in space (triangulation, multilateration, particle filter), and filters (LSM, Kalmann filter) are explained. Using development board ESP-32 UWP Pro localization system is realized, using TWR and particle filter. This system was calibrated and tested in a real environment.

Target tracking from radar images
Fojtík, Jakub ; Götthans, Jakub (referee) ; Maršálek, Roman (advisor)
This bachelor's thesis deals with data processing methods for target detection and subsequent target tracking from radar images. Two algorithms are presented, namely CFAR (constant false alarm rate) and BSTC (binary successive target cancelation). The BSTC algorithm continues to be used as the default detection algorithm for subsequent target tracking and evaluation, for which several algorithms are described here, however, special attention is paid to the Kalman filter, which, like the CFAR and BSTC algorithms, is developed here in the MATLAB programming environment in a single and multiple target tracking application.

Design of electronic control unit for rotational inverted pendulum
Sopoušek, Radek ; Appel, Martin (referee) ; Brablc, Martin (advisor)
The scope of this thesis is to create a dynamic model of the pendulum, design the control in inverse position, implement the swing-up task and add a controlled fall to a stable position, design and integrate the hardware with the existing pendulum model and implement the control using a state machine. The reader is introduced to the elements of a real device. A model is analytically constructed to be used for parameter identification and control design. Swing-up control is implemented using the moment method and two energy methods representing single and multiple-swing behavior. In the inverse position, the pendulum is controlled using LQR controller. For controlled fall to stable position, PD controller is used. For control purposes, a developmental microprocessor board was selected and integrated into the existing model with minimal changes to the functionality. The control was performed using a state machine whose robustness to parameter changes was experimentally verified.

Multiaxis feedback cooling of particle in optical trap
Číž, Adam ; Adámek, Roman (referee) ; Brablc, Martin (advisor)
This thesis deals with a design and implementation of algorithms for multiaxis feedback cooling (which means positional control) of a particle in an optical trap with use of Kalman filter. Two control methods are proposed here, each of which is intended for use of a different actuator: a laser intensity modulator or a pair of electrodes. Next, the implementation of both methods on hardware with an FPGA is described. Functioning of both proposed algorithms is proven by a numerical simulation. In addition, the functioning of the control using electrodes is demonstrated by an experiment with an optical trap. The second method is fully prepared for use in an experiment.

Object Detection and Tracking Using Interest Points
Bílý, Vojtěch ; Hradiš, Michal (referee) ; Juránek, Roman (advisor)
This paper deals with object detection and tracking using iterest points. Existing approaches are described here. Inovated method based on Generalized Hough transform and iterative Hough-space searching is proposed in this paper. Generality of proposed detector is shown in various types of objects. Object tracking is designed as frame by frame detection.

Robot for Robotour 2012
Vass, Robert ; Luža, Radim (referee) ; Rozman, Jaroslav (advisor)
The aim of this article is the theoretical analysis, proposal and implementation of a method for the operation of an autonomous robot for Robotour 2012 with the help of camera and sensor usage. Key issues to be faced are the computer vision, robot sensing uncertainty and the localization problem. Firstly, road extraction is achieved by using colour segmentation. Secondly, for the combination of information of different uncertain sources, Kalman Filter is proposed. Finally, the information received by the camera which serves for the building of an occupancy grid map corrected by sensors is de facto the representation of environment for the robot.

Network Anomaly Detection
Pšorn, Daniel ; Puš, Viktor (referee) ; Kořenek, Jan (advisor)
This master thesis deals with detecting anomalies methods in network traffic. First of all this thesis analyzes the basic concepts of anomaly detection and already using technology. Next, there are also described in more detail three methods for anomalies search and some types of anomalies. In the second part of this thesis there is described implementation of all three methods and there are presented the results of experimentation using real data.
