摘　　要：采用当前方法绘制灾后区域地形时,测绘所用时间较长,绘制结果与实际区域地形之间存在较大误差。为此,该文提出基于中继通信技术的灾后区域地形特征点无人机精细测绘方法。采用中继通信技术获取灾后区域地形影像,基于共线方程理论获取灾后区域地形特征点对应的坐标,利用POS辅助控制三角测量方法处理影像,通过高精度物方DEM匹配技术实现灾后区域地形的绘制。When the current method is used to map the post disaster regional terrain, the mapping takes a long time, and there is a big error between the mapping results and the actual regional terrain. For this reason, a precise mapping method of UAV based on relay communication technology is proposed. After the disaster, the terrain image is obtained by relay communication technology, the coordinates corresponding to the terrain feature points are obtained based on the collinear equation theory, the image is processed by POS auxiliary control triangulation method, and the terrain is drawn by high-precision object DEM matching technology. The experimental results show that the proposed method has high efficiency and accuracy.
