This bachelor thesis addresses the spatial localization of objects from an unmanned aerial vehicle (UAV) using optoelectronic sensors. The objective was to design a sensor system, select suitable components, and subsequently integrate them into a single unit. A laser rangefinder (LiDAR) and a digital camera were selected for the system. Based on a market survey, a stabilizing gimbal was also chosen, although it was not part of the final integration. The theoretical part of the thesis describes the operating principles of LiDAR and mathematical models of digital camera projection and geometry, explaining their practical application in linking image data with real-world spatial coordinates. In the practical part, software for data acquisition and processing was developed within the ROS 2 framework using the Python programming language. The experimental phase included the theoretical verification of sensor specifications, camera calibration, laser beam divergence measurement, and local localization testing. Following ground testing, the integrated sensor system was successfully validated by flight tests onboard the unmanned aerial vehicle. The achieved results confirmed that the system can accurately and reliably determine the position of objects. The main contribution of this thesis is a functional solution for target localization over greater distances, thereby expanding current capabilities and serving as a comprehensive pre-prepared platform for further development and future practical deployment.

Process of defence
Student obhájil bakalářskou práci s výhradami. V rámci obhajoby dokázal přesvědčit komisi o správnosti svých postupů a navrženého řešení. V průběhu odborné rozpravy reagoval na dotazy oponenta a doplňující dotaz ohledně chyby měření vzdálenosti LiDARem. V obecné diskusi dovysvětlil, které komponenty dosadil na použitý dron a diskutoval finanční náročnost těchto řešení. Dále byl dotázán na měření vzdálenosti stereofotogrammetrií.
