摘要
针对利用UX5无人机进行低空摄影测量,获取数字线划图(DLG)的过程进行描述,通过对实际无人机影像数据的处理,将空三测量精度与SDCORS、GPS-RTK实地检测精度进行比较分析,验证了无人机低空摄影测量能够满足1∶1000地形图测绘的精度要求,为今后同类测量项目提供参考和借鉴。
A description is made on process of using UX5 unmanned aerial vehicle for photography measurement of low latitude so as to get digital line graphic. Comparative analysis is conducted on accuracy of field detection of aerotriangulation with ShanDong Continuously Operating Reference Station System （SDCORS） and GPS Real - time kinematic （RTK）. It is found that unmanned aerial vehicle for photography measurement of low latitude can satisfy the needs of 1：1000 topographic map surveying and mapping and can be applied to other similar projects.
