摘　　要：机载POS系统利用惯性导航技术与GPS等技术的特征优势,能够准确获取航空摄影相机曝光时刻的姿态参数与位置参数等外方位元素,实现了在省略空中三角测量加密与地面控制点等工序基础上的定向测量,生产效率与作业成本等随之优化。文章主要对POS辅助航空摄影测量技术及应用进行阐述,分析系统误差来源与应用需求等,希望对航空摄影测量技术的优化发展起到积极的参照作用。The airborne POS system can accurately acquire the external orientation elements such as attitude parameters and position parameters at the exposure time of aerial camera by using the characteristics of inertial navigation technology and GPS technology, and realize the orientation measurement based on omitting the process of aerial triangulation encryption and ground control points, so as to optimize the production efficiency and operation cost. This paper mainly expounds the POS aided aerial photogrammetry technology and its application, analyzes the source of system error and application demand, hoping to play a positive reference role in the optimization and development of aerial photogrammetry technology.
