Application of Airborne LiDAR in High-Standard Farmland Surveying and Mapping
ZHENG Zhiqing
Abstract：Currently,China's low-altitude economy is in a critical growth period,and unmanned aerial vehicle(UAV)mapping technology plays an important role and has extensive application scenarios in the low-altitude economy.Taking the high-standard farmland surveying and mapping project in Miaozhuang Town,Ninghe District,Tianjin as an example,this paper uses the vertical take-off and landing fixed-wing CW-25E UAV equipped with the JoLiDAR-LR lidar and orthophoto camera integrated device to obtain the point cloud and orthophoto image data of the survey area,and summarizes in detail the main processes and key technologies of field point cloud data collection,high-precision radar POS post-processing calculation and point cloud analysis.The results show that this method has a high degree of automation and can significantly improve the efficiency of surveying and mapping operations.The elevation error of the analyzed LiDAR point cloud data is less than 2 cm,which meets the accuracy requirements for large-scale topographic mapping results in high-standard farmland construction.
