摘要:
利用GPS三维信息确定像片控制点坐标的方法和精度，经内业解析空三加密和外业实施地检测，证明该方法不仅能够满足1:10,000比例尺航测成图的精度要求，而且较传统联测方法可提高工作效率3~10倍。对于通视条件困难和已知大地点较少的测区，用GPS联测像控点无疑是最佳方法。Using GPS three-dimensional information to determine the method and precision of control point coordinates of the photograph, and through the implementation of industry sector three-encryption detection and the analytic space work inside and outside, we prove that the method not only meets the 1:10,000 scale precision aerial mapping, but also improves the efficiency of 3 - 10 times more than traditional union measuring method. For survey areas under difficult visibility conditions and with less known large places, using multiple GPS control points is the best method.
