摘　　要：基于无人机摄影测量技术,对盛海花园小区进行了1∶500大比例尺地形图测绘,获得了高精度数字线划成果。通过与RTK测图成果比对,验证了地物点相对于邻近平面控制点的点位中误差、地物点相对于邻近地物点的间距中误差和高程中误差符合规范精度要求。针对无人机测绘的不稳定性,提出了稳健性精度及其验证方法,经检验平面稳健性精度高达93.2%,高程稳健性精度达到86.4%,因此不失为一种可行的测图新手段,对于提高测绘效率具有重要意义,也为类似测绘工程提供一个可借鉴技术依据。At present, UAV surveying and mapping is widely used in the field of Surveying and mapping.Based on the photogrammetry technology of UAV,the 1:500 large scale topographic map of shenghai garden residential area was surveyed and mapped,and the high precision digital line graphic results were obtained.By comparing with RTK mapping results, it was verified that the error of mean square of ground objects relative to adjacent plane control points, the error of mean square of ground objects relative to adjacent ground objects and the elevation error of mean square meet the code accuracy requirements.In view of the instability of UAV surveying and mapping,this paper presented a robust accuracy and its verification method. By computing,the plane robustness accuracy is 93.2% and the elevation robustness accuracy is 86.4%,therefore, it is a feasible new means of Surveying and mapping, which is of great significance to improve the efficiency of Surveying and mapping, and also provides a reference for similar surveying and mapping projects.
