摘　　要：免像控大比例尺无人机测图是航空摄影测量发展的趋势。以天狼星无人机航测系统为例,介绍了固定翼无人机的基本结构,阐述了免像控大比例尺无人机测图的流程,探讨了自适应航线设计、POS辅助空中三角测量等无控制点航空摄影测量数据处理的关键技术。结合工程实例,将得到的DEM、DOM中的明显地物特征点坐标与对应地面检核点的实测坐标进行对比分析,验证了天狼星无人机航测系统应用于1∶500测图的可行性。Large scale mapping using unmanned aerial vehicle(UAV)without image control point is the trend of aerial photogrammetry.Taking Sirius unmanned aerial system(Sirius-UAV)for example,we introduced the basic structure of fixed wing UAV,expounded the process of large scale UAV mapping without image control point,and discussed the adaptive route design,POS aided aerial triangulation,and other key technologies of data processing in aerial photogrammetry without control point.Combining with the engineering example,through comparative analysis between the feature points coordinates of the obvious objects in DEM and DOM and the measured coordinates of corresponding ground check points,we verified the feasibility of applying the Sirius-UAV Photogrammetry System to 1∶500 mapping.
