摘要
将通过控制点精度检验和碎部控制点精度检验分析,基于无人机影像数据和无人机激光雷达技术制作的1∶500大比例尺地形图精度,结果显示,无论控制点还是碎部点,其平面位置精度完全满足1∶500比例尺地形图的要求;其高程精度方面,控制点和平地碎部点的高程精度也满足1∶500比例尺地形图的要求,高山地区的碎部控制点精度基本满足1∶500比例尺地形图的要求。
The accuracy of 1∶500 large-scale topographic map based on UAV image data and UAV LiDAR technology were analyzed by control points and detail points. The results show that the plane position accuracy checked by control points and detail points fully meets the requirements of 1∶500 scale topographic map. The accuracy of elevation checked by control points and ground detail points of level ground also meets the requirements of 1∶500 scale topographic map, while basically meets the requirements of 1∶500 scale topographic map.
