摘要
基于摄影光学理论，分析了相机在空气中和水下成像基点位置关系，提出水下摄影三点共线理论，并推导出相机在水下主距变化模型；分析了相机水下摄影视场和畸变大小的变化，设计了水下摄影测量相机标定方法；最后通过水下摄影试验标定，验证了水下摄影三点共线理论的正确性和水下相机标定方法的实用性。
With a brief introduction of optical theory of photogrammetry, the relation of the location of datum marks is described in camera lens system between air and underwater. The collinearity theory of underwater photogrammetry is proposed, and the variety of principal distance of underwater camera is illustrated. After the analysis of distortion and view of underwater photography, the camera underwater calibration method is described. One calibration test on underwater camera was done. The results indicate that the collinearity theory of underwater photogrammetry is right and the method of underwater camera calibration is suitable.
