影像相对定向与基础矩阵关系的分析

Research on relationship between relative orientation of photogrammetry and fundamental matrix in computer vision

基于立体像对相对定向与极线几何的内在一致性,针对相对定向元素的个数、基础矩阵的自由度以及参数间的对应转换问题,分析了相对定向元素与基础矩阵要素间的对应转换关系。通过以基础矩阵求解航空影像的相对定向实验,说明了基础矩阵相关解法的计算结果能够转换为像对相对定向的结果,在剔除错误匹配点后能够获得较高的精度。

This paper analyses and discusses the relationship between the relative orientation and the funda- mental matrix based on the number of the relative orientation, degrees of freedom of the fundamental matrix and the corresponding relations between their parameters. Experimental results of real images showed that the proposed ap- proach was practicable, gives great inspiration to the understanding of the mathematical principle about them, and the results of the Fundamental Matrix can be converted to the ones of relative orientation. After getting rid of the er- roneous matched points, the relative orientation through Fundamental Matrix can get more precise calculation re- sults.
