基于POS系统直接地理定位快速制作DOM

QUICK COMPILATLON OF DOM BASED ON POS DIRECT ORIENTATION

基于POS系统辅助航空摄影测量技术可以在航空摄影的同时直接获取曝光瞬间航摄仪的空间位置和姿态参数,通过对集成系统误差进行检校与改正,即可获得用于正射影像图制作的高精度外方位元素。本文结合实际生产试验,较系统地介绍了采用该技术进行正射影像图快速制作的方法,并对关键技术环节进行分析,总结了基于POS系统直接地理定位快速制作DOM的方法和流程。

The POS - supported same time of aerial photography. photogrammetry can determine the position and the altitude of the sensor at the Considering the oriented translational offsets and rotations between the POS and the camera, the authors hold that the accuracy performance of direct orientation measurement is sufficient to make orthophoto. This paper deals with the course and the crucial technology for the quick compilation of DOM.
