多基线近景摄影测量连续像对相对定向

Research on Dependent Relative Orientation in Multi-baseline Close-range Photogrammetry

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进行两种相对定向方法解算,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.

Multi-base line photogrammetry with big rotation angles is needed to obtain the information of the target.The paper presents formulas of dependent relative orientation in multi-base line photogrammetry.With the baseline components and direction cosines as the parameters,photos can be taken at any place and with any rotation angles,without any limitation on the initial values.And also another method is introduced to solve the same problem.The experiments with no-metric cameras on experiment field prove that the elements of relative orientation can be correctly calculated with both of these two algorithms.
