双介质摄影测量的相对定向

Relative Orientation for Two-Media Photogrammetry

本文导出了双介质摄影测量的共面条件方程,它与单介质摄影测量时的共面条件方程有十分相近的形式,并推导了共面条件方程的线性化形式;针对与单个质摄影测量相对定向的区别,讨论了双个质摄影测量相对定向的计算,从而从理论上完备地解决了这一问题;最后给出模拟数据的计算结果,证实了所建立的相对定向方程和相应计算策略的正确性。

This paper focuses on the analytical relative orientation for two-media photogrammetry. With a brief introduction of the image-forming equation, we develop the coplarity equation which is very similar in form with the one in one medium case. Considering the differences from one-medium photogrammetry, the computation strategy of the relative orientation for two-media photogrammetry is studied, including the linearization of the equation, the correction of the refraction, and especially the determination of the boundary plan between the two media. Simulated test results are shown to verify the developed equations and their computational strategy.
