Abstract:

[Objective] This study aims to address key issues related to the takeoff and landing site, inspection range, and automatic inspection capability of fixed wing unmanned aerial vehicles during large-scale inspections, with the goal of improving overall performance. [Methods] This study is based on the CortexA53 architecture of the inspection hardware system, which is embedded in the Debian operating system. It combines Fourier transform gradient direction histogram and a self-disturbance rejection algorithm to process fixed wing unmanned aerial vehicle takeoff and landing and inspection of image information. An active disturbance rejection controller is employed to enhance the aircraft’s wind resistance during takeoff and landing. This study adopts a small object detection method based on target characteristics to perform object retrieval on images. [Results] Through experiments, the efficiency and coverage of the task have significantly increased by 11.9%. This technical approach offers a reliable and efficient solution for large-scale inspections in complex environments, effectively promoting the widespread application of drone inspection technology in multiple fields.
