摘　　要：在山地地形中,用轻型固定翼无人机为航摄平台,采用POS数据与地面控制点相结合的方式进行空三加密并生产1∶500数字线划图,利用控制网精度以及DLG实测精度对测绘精度进行验证。实践证明了在复杂地形条件下利用无人机生产大比例尺地形图的可行性,并提出了控制精度的实用方法。In mountainous terrain,with the light fixed-wing UAV aerial platform,use a combination of POS data and ground control points to complete aerial triangulation and the production of 1 ∶ 500 DLG,and text verify of the surveying precision used control network precision and the actual measurement precision of DLG. Practice has proved the feasibility of producing large scale topographic map using the UAV aerial system in conditions of complex terrain,and put forward practical method of control accuracy.
