摘　　要：无人机测绘系统已广泛应用于局部基础测绘、专题测绘等领域。定位精度是该系统的关键，本文描述了无人机影像的定位精度评估模型，分析了利用组合导航测量单元数据直接定位和基础地理信息支持下定位两种定位方法的理论精度，最后利用无人机影像数据实验对评估模型进行了验证。UAV surveying and mapping system has been widely applied in local basic mapping, special thematic mapping and other fields. The positioning precision is the key for the system. This paper describes the positioning precision evaluation model of UAV image, and analyses the theoretic precision of the two positioning methods （ the direct positioning method using integrated navigation measure unit data and the positioning method supported by basic geographic information）. Finally, the evaluation model is verified by test using UAV image data.
