机载LiDAR在高标准农田建设测绘中的应用研究

Research on the Application of Airborne LiDAR in High-standard Farmland Construction Surveying and Mapping

随着测绘科技的进步,机载LiDAR技术日趋成熟,可为高标准农田建设项目提供全方位、实时的精准影像支持。本文以舒兰市平安镇永平村某平原区为测区,采用机载LiDAR技术快速获取真彩三维激光点云数据,生成高精度、高分辨率、实时性强的DEM、DSM、TDOM、DLG及三维模型等丰富测绘成果,探讨机载LiDAR技术在高标准农田建设测绘中的实际应用,验证了机载LiDAR技术所获取的点云数据在平面和高程精度上可满足1∶1 000比例尺地形图测绘的生产要求。

With the progress of surveying and mapping technologies,airborne LiDAR technology is becoming more and more mature,providing comprehensive and real-time accurate image support for high-standard farmland construction projects.This paper takes a plain area of Yongping village,Ping′an town,Shulan city as the survey area and uses airborne LiDAR technology to quickly obtain true color 3D laser point cloud data to generate high-accuracy,high-resolution,real-time rich surveying and mapping results such as DEM,DSM,TDOM,DLG and 3D models.It explores the practical application of airborne LiDAR technology in high-standard farmland construction surveying and mapping and verifies that the point cloud data obtained by airborne LiDAR technology can meet the production requirements of 1∶1 000 scale topographic map surveying and mapping in planimetric and vertical accuracy.
