Abstract
This paper discusses the application of UAV technology in the field of surveying and mapping, especially the key technologies, challenges and optimization suggestions. Flight planning and route design are the premise to ensure the safe and efficient completion of the mapping tasks of the UAV. By accurately planning the flight path, it can effectively avoid the terrain obstacles and improve the efficiency of data collection. Photogrammetry and data processing are the core links of uav mapping. Through the high-precision sensor and advanced GPS positioning technology, the UAV can capture ground images and transmit them to the ground station in real time for follow-up processing to generate high-precision topographic map or three-dimensional model.3 d modeling and topographic analysis technology can further improve the intuition and practicability of surveying and mapping results, and provide strong support for topographic analysis and disaster monitoring. Uav faces many challenges in the topographic mapping of mountainous areas, and the terrain complexity and flight difficulty are the primary problems. The complex and changeable terrain in mountainous areas puts forward higher requirements for the flight stability and safety of uav. Unstable signal transmission and the influence of climatic conditions are also important factors, which may lead to disrupted data transmission or decreased data quality. The low technology integration also limits the deep application of UAV in the field of mapping. For these challenges, corresponding optimization suggestions are presented. Through the application of high-precision terrain modeling and intelligent obstacle avoidance system, the flight safety and data acquisition efficiency of UAV in complex terrain are improved. Enhance the signal transmission capacity, using high-performance communication module and relay station and other technical means to ensure the stability and reliability of data transmission.
