Abstract 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.
