Traffic lanes and interruptions detection
Dojava, Marian ; Červinka, Luděk (referee) ; Horák, Karel (advisor)
This master´s thesis deals with depiction aplication of camera like sensitive element for assisting system of car. It was proposed, how find a road, a lane and a obstacle on roadways. Only one camera was aplication for it. Solution is realized by methods, that are based on color and gradient of image. It applies simple methods and methods with mathematical model. Result is sum of method and its test and comparing. Realization of my program is present at resume of this thesis.

Radar sensors in mechatronics
Pulec, Matěj ; Formánek, Martin (referee) ; Brablc, Martin (advisor)
This work is studying the possibilities of using radar sensors in mechatronics. The theoretical part describes the basic principles of the mm-Wave FMCW radar sensor, along with several examples of their possible applications. The practical part describes three experiments testing the capabilities of this sensor. In these experiments, the the radar was found to be able to accurately and reliably track the position and speed of a moving object. However, problems arose when trying to determine the position of static objects and also when detecting the shape or orientation of both dynamic and static objects. For these purposes, the the tested radar appears to be an unsuitable type of sensor.

Mobile robot sensor system
Juhás, Miloš ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
In this Bachelors thesis is processed the basic theoretical knowledge needed to design sensory system for a small mobile robot and the sensory system itself is designed. Thesis describes the working principle of tactile, optoelectonic and ultrasound sensors, their basic features, advantages and disadvantages. Next there are processed known prospects of sensors electrical schemes for line following and obstacle detection sensors and commercialy available solutions are briefly described. In the second part there is, based on introduced principles, experimental schemes and measurements, the sensory system itself designed, which is capable of advanced detection abilities and microprocessor conducted data processing. The design is focused on power usage optimisation, control software efficiency and extended universality of designed system. Part of the thesis are libraries of functions required for simple control and sensory system application. In the epilogue there are listed and evaluated the testing results and measured parameters of designed system.

Road detection using data from mobile robot camera
Peška, Jaroslav ; Horák, Karel (referee) ; Petyovský, Petr (advisor)
Bachelor thesis deals with the problem of road detection by mobile robots using data obtained from its camera. First, current solutions are researched and considered for use in the proposed algorithm. Afterwards we define limit parameters of the entire solution. An automatic process using human-created reference was then devised to programatically determine the accuracy of individual versions of proposed solutions. First, an initial version of the solution was implemented, which was subsequently optimized and accelerated using GPGPU. Lastly, proposed algorithm is evaluated and possible future changes are outlined.

Quadrocopter Navigation and Control
Doležal, Karel ; Orság, Filip (referee) ; Herman, David (advisor)
This paper focuses on autonomous navigation of AR.Drone quadrocopter in outdoor environment. The goal is to follow a specified route and land autonomously on a platform placed at the destination. Firstly, the AR.Drone platform, its development kit and sensor extension with GPS and a magnetic compass are described. Then, the navigation architecture of a control program is presented describing important blocks and its' individual tactics. Localization of the landing platform is based on its color. The video is also used to detect nearby obstacles using optical flow calculation suppressing the quadrocopter movements and to avoid the greater changes in the image. The control program implementation is then tested in real environment and the results are presented.
