多视几何中外参数与航测外方位元素的相互转化

Mutual Transformation Between Camera External Parameters in Multi-view Geometry and Exterior Orientation Elements in Photogrammetry

多视几何与传统摄影测量存在很多相似性,其相关理论与技术发展对传统摄影测量极具借鉴意义,然而如何将多视图几何理论融入传统摄影测量仍是有待解决的问题。针对如何实现多视图几何中相机外参数与摄影测量中相机外方位元素相互转换展开研究,通过详细介绍与分析两者在各自理论系统中的具体含义,推导并给出两者的互相转换公式。实现多视图几何中外参数与摄影测量中外方位元素转换,对于两学科间理论成果的相互补充具有实际意义。

There are many similarities between multi-view geometry and traditional photogrammetry,and the theory of multi-view and its related theory and technology development have great reference value for the traditional photogrammetry,how to syncretize multi-view geometry theory into traditional photogrammetry is still a problem to be solved.This paper studies how to realize the mutual transformation of camera external parameters in multi-view geometry and camera external orientation elements in photogrammetry,by way of detailed introduction and analysis of the specific meaning of them based on each theoretical system,then derives and gives the formula of the mutual transformation between them.It is of practical significance for the mutual complement of the theoretical results between the two disciplines to achieve the mutual transformation between the camera external parameters inmulti-view geometry and the exterior orientation elements in photogrammetry.
