Abstract
The main function of pumped storage power station is to store more electric energy,usually in order to achieve this purpose,the site of the power station is usually located in the area with a large height difference and high vegetation coverage.In such areas,the traffic conditions are mostly poor,and making it difficult and costly measure by conventional methods,and the accuracy is also difficult to meet the requirements.In recent years,the development of airborne Lidar photogrammetry technology has played a good role in solving these problems.Combined with the practical experience of the actual project production,this paper expounds various aspects of survey area analysis,flight design,point cloud and image data acquisition,data preprocessing,point cloud classification,and aerial image processing.Through the final accuracy analysis,it proves that airborne li-dar technology can still meet the accuracy requirements of terrain surveying and mapping in areas with large al-titude difference and high vegetation coverage.It has a broad application prospect for water conservancy and hydropower aerial photogrammetry in the future.关键词
