摘　　要：基于海上落点测量需要设计了一种算法,该算法根据两点连线在与其共面的两个观测方向上的正投影长度计算两点距离。在此基础上设计了一种摄影测量实现方法,并通过仿真和实验方法进行了精度验证。该方法在解决海上目标落点精度测量等某些特定问题时具有方法便捷的优点,且精度符合试验测量需求。A algorithm is designed based on the need of falling point measurement at see,which calculates the distance be⁃tween two points according to the orthographic length of the two points in the observation directions coplanar with the two points.On this basis,a photogrammetric implementation method is designed,and the accuracy is verified by simulation and experiment.This method has the advantages of convenience in solving some specific problems such as the accuracy measurement of the target landing point at sea,and the accuracy meets the requirements of experimental measurement.
