消费级无人机在大比例尺测图中应用与精度评价

摘要

以分别搭载大视场角普通相机和鱼眼相机的消费级无人机为例，在对相机的高精度标定基础上，选取典型丘陵和山地实验区分别对两种消费级无人机大比例尺测图能力进行实验和精度评价，结果证明消费级无人机在合理的航测方式下，其测图结果的空三精度、分辨率及高程精度均可满足国家1∶500大比例尺地形测图的精度要求，可以推广应用到小范围大比例尺测图和修测任务中。%T his paper makes a mapping accuracy analysis on mountain areas by using consumer unmanned aerial vehicles (UAVs) amounted with a large field of view angle of ordinary camera and a fisheye camera respectively based on high accurate camera calibration .The experiment results demonstrate that UAV is feasible to be applied to the large scale mapping , of w hich the accuracy of aerial triangulation , map resolution and altitude results can meet the requirements of national 1∶500 scale topographic mapping with proper flight configuration .
