低空遥感平台中POS姿态角与外方位角元素间的转换方法

低空遥感平台中所用的INS角度系统与摄影测量外方位元素中的角度系统不同,需要经过转换和纠正。本文分析了两种角度系统的概念和关系,并推导出了二者间转化的数学公式。经过设计分组实验验证,证明方法可行有效,且用于影像预处理的改善效果明显。

Angle System Conversion Method between POS and Elements of Exterior Orientation in Low-Altitude Remoet Sensing Platforms

The angle systems of INS used in low -altitude remote sensing platforms is often different from that of elements of exterior orientation in photogrammetry , conversion and correction work are needed .The paper analyzes the relationship between the two angle systems and derives a mathematical formula for their easy transformation .Group experiments are designed , and results prove that the proposed method is feasible and effective , and it can improve the effect of image pre -processing obviously .
