Research and Application of UAV Railway Inspection Path Based on BeiDou Positioning Optimization
Abstract：Traditional railway inspection methods have defects such as low efficiency and detection blind spots. Unmanned aerial vehicle (UAV) technology, with its flexible mobility and wide-area coverage capabilities, has shown significant advantages in the field of intelligent detection of railway infrastructure. This paper constructs a high-precision positioning technology framework based on the BeiDou satellite navigation system, and achieves intelligent optimization of UAV inspection paths by fusing multi-source sensor data. The results show that integrating this technology with geographic information systems can realize intelligent planning of inspection paths, significantly improving inspection efficiency, shortening inspection time, and ensuring full coverage of key areas. The scheme meets the requirements of railway inspection standards in terms of positioning accuracy and real-time performance, providing technical support for the inspection of infrastructure such as track structures and contact networks in complex terrains.
