The thesis focuses on the research and analysis of first-person view drones. The aim of the thesis is to examine various technical aspects of first-person view drones and to test the performance of a digital first-person system under different conditions.
In the theoretical part of the thesis, we first provided a brief historical and developmental overview of quadcopters and first-person view technologies. We analysed current technical solutions for digital first-person view systems available on the market. Finally, we presented the key components of drones, including the frame, motors, speed controller, flight controller, and first-person view system.
In the practical part, we tested the use of the CaddxFPV Nebula Pro Vista air unit on a drone. Our aim was to test the quality of the video signal at different transmission power values and with various obstacles. The results showed that the quality of the video signal and latency greatly vary depending on the transmission power, obstacles, distance, and antenna configuration. In open areas where there were no obstacles, the signal remained stable up to 1 km. However, at lower transmission power values and with the presence of obstacles such as walls and trees, the signal quality quickly deteriorated. Directional antennas improved signal stability and reduced latency but did not completely eliminate issues caused by obstacles.
First-person view drones have proven to be extremely versatile and offer a wide range of possibilities in their application, such as competitive flying, filming, exploration and recreational purposes. A proper understanding of the operation of drones and their limitations is crucial for safe and efficient use. Pilots must have the knowledge and skills to adjust their flying according to the specifics of the environment, equipment capabilities, and other flight conditions.
