Ball Trajectory Estimation from Images
Heřman, Zdeněk ; Materna, Zdeněk (referee) ; Španěl, Michal (advisor)
Main goal of this thesis is to design a method for ball trajectory estimation from images, and to evaluate the proposed method using an experimental setup. Both the method and the experimental setup were designed to be suitable for a golf simulator. The proposed solution uses a stereo camera for flying ball tracking. Accurracy of the ball detection in images is further improved by using a pulsed light source. A solution reaches an accuracy that can be compared with cheaper simulators that already exist. Nevertheless prize is lower.

Image Processing for Golf Simulator
Heřman, Zdeněk ; Herout, Adam (referee) ; Španěl, Michal (advisor)
This thesis describes design and practical realization of a golf simulator. It includes specifications of the hardware, that is a necessity for such simulator, and implementation of the detection of a golf swing and ball flight. The simulator has to fulfill several conditions that were stated at the beginning of the draft. One of the most important conditions was low purchase price, and therefore the simulator is based on common USB cameras Playstation Eye 3. The main goal was to create a user friendly simulator, that will be appropriate both for indoor and outdoor conditions. The final solution was compared with Full Swing simulator. The accuracy of our simulator was far better than the compared one at short game and putting through the use of scanning the ball right after the start of its flight. Accuracy at putting ranged: speed of the ball +/- 0.2 m/s, launch angle +/- 1 degree and flight angle +/- 0.8 degrees.

Golf Ball Flight Simulation and Visualization
Opletal, Petr ; Beran, Vítězslav (referee) ; Španěl, Michal (advisor)
This diploma thesis deals with the simulation and vizualization of a golf ball flight. The final application is powered by the Unity engine and the PhysX physics library. The application includes the implementation of basic golf ball aerodynamics and advanced vizualization including simple gaming logic. The final solution can be used as a part of a cheap golf simulator. The text contains a theoretical introduction, existing solutions, basics of golf ball aerodynamics, an application design, the creation of courses and implementations. The conclusion of the diploma thesis describes experiments with the final solution and summarizes the achieved results.
