不同转角系统的外方位角元素转换方法与应用

The method and application of exterior orientation angle elements transformation for different rotation angle system

针对大多数摄影测量处理软件仅使用某一种转角系统的外方位角元素,导致不同软件的影像外方位角元素成果往往不能通用和不同转角系统的影像外方位角会让缺乏经验的作业人员产生混淆,从而造成错误的结果这一现象,该文对目前常见的摄影测量软件采用的3类外方位角元素的转角系统进行研究,推导出不同转角系统之间的对应关系和转换计算方法,并编写了几类常见摄影测量软件的转角系统和数据格式转换程序。通过实验证明了该方法的正确性,从而实现了部分摄影测量生产流程的优化。

In view of the phenomenon that most kinds of photogrammetry software support the exteri- or orientation elements of one type rotation angle system,therefore the exterior orientation elements of one type cannot be used in different photogrammetry software,and inexperienced workers were confused by the angles of different rotation angle systems,so it caused the incorrect result,this paper studied three types of rotation angle systems which was used in common photogrammetry software,and deduced the relationship and transformation algorithm between different rotation angle systems.And a conversion pro- gram was coded for transformation of the rotation angle systems and the data formats in different common photogrammetry software.This algorithm and conversion program was proved to be correct by the experiment results.And the process of some photogrammetry productions could be optimized by the algorithm and the conversion program.
