摘　　要：针对无人机摄像测量技术测量结果精度不足的问题,以实际工程为例,通过飞时达方网格测算技术和PhotoScan软件建模技术进行土方计算,利用点云分类和高程修正的方式对无人机摄像测量数据点进行优化,消减遮挡物对地表高程的影响,结合无人机测量布点技术,提出地面控制点布置方案。优化后的测量数据与RTK土方测量计算进行精度比对,结果表明:利用无人机测量技术,不仅能节约工作时间,简化工作流程和所需设备,同时也可在多地形下进行精确的土方测量工作。In view of insufficient accuracy in the measurement results of UAV camera measurement technology,this paper is based on actual cases,through use of FTSE square mesh measurement technology and PhotoScan software modelling technology for earth calculations,the use of point cloud classification and elevation correction to optimize the UAV camera measurement of the data points,eliminate the impact of obstructions on the ground surface elevation.surface elevation,and combined with the UAV measurement pointing technology,the ground control point layout scheme is proposed.The optimised measurement data are compared with the RTK earthwork measurement calculations for accuracy,and the results show that using UAV measurement technology not only saves working time and simplifies the working process and required equipment,but also allows accurate earthwork measurement in multiple terrains.
