Technology of sports training and possibilities of its implementation with athletes is presented at the beginning of the diploma thesis. The introduction comprises commercial solutions for sports in general, specialized solutions for tennis follow.
Based on findings which indicate lack of affordable and usable solutions in tennis, further focus in the thesis is made on the presentation of the process of creating a system for defining the position of a tennis player. This consists of the Localino system, which is based on the radio technology Ultra Wide Brand (UWB) and on the cost-effective, miniature and wide accessible motion sensor Inertial measurement unit (IMU), which belongs to the Micro Electro Mechanical System (MEMS). Special emphasis is placed on the description of the UWB technology and advantages of its usage in general and for the case of positioning. Different techniques of positioning and description of all mechanical components in the system for defining the position of a tennis player are also explained.
The next chapter in the thesis focuses on the description of the application which performs synchronous capture and data analysis for defining a tennis player’s position in real time. The code consists of a set of functionally defined blocks written in the software environment LabVIEW. Explanation of the code written in the software environment Arduino IDE executed on more microcontrollers is also explained.
The following part of the thesis comprises a description of processes of testing the created system for defining the tennis player’s position, firstly in laboratory and afterwards in real-life environment on the tennis court. Precision of this system is verified by Qualisys, a system of cameras for optical tracking.
The conclusion includes results of the analysis of gained data at testing, which are accompanied by comments and recommendations for improving the system.
