多基线近景摄影测量连续像对相对定向

根据近景摄影测量多基线、大倾角摄影的情况，推导了多基线近景摄影测量连续像对相对定向的公式，提出了以基线分量以及方向余弦为参数的解算方法，从而克服了非线性的共面条件方程式在解算时对摄影位置及姿态的限制。对摄影测量手册中相对定向方法进行了介绍。利用非量测数码相机对实验场地所拍摄的数据对两种相对定向方法进行解算，获得了精度较高的结果，验证了两种算法的正确性及稳定性。

Abstract: According to the situation that in close-range photogrammetry, sometimes we need employ multi-base line photogrammetry with big rotation angles to obtain the information of the target, this paper deduces the formulas of dependent relative orientation in multi-base line photogrammetry. With the baseline components and direction cosines as the parameters, we can take photos at any place and with any rotation angles, without considering the limitations of the initial values. And also another method is introduced which also can solve this problem. In particular, through the experiments with no-metric cameras on experiment field, it is proved that with both of these two algorithms, the elements of relative orientation can be correctly calculated.
