多基線近景攝影測量連續像對相對定向

根據近景攝影測量多基線、大傾角攝影的情況，推導了多基線近景攝影測量連續像對相對定向的公式，提出了以基線分量以及方向余弦為參數的解算方法，從而克服了非線性的共面條件方程式在解算時對攝影位置及姿態的限制。對攝影測量手冊中相對定向方法進行了介紹。利用非量測數碼相機對實驗場地所拍攝的數據對兩種相對定向方法進行解算，獲得了精度較高的結果，驗證了兩種算法的正確性及穩定性。

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.
