Camera calibration via bundle adjustment is a well-established standard procedure in\nsingle-medium photogrammetry. When using standard software and applying the collinearity\nequations in multimedia photogrammetry, the effects of refractive interfaces are compensated in\nan implicit form, hence by the usual parameters of interior orientation. This contribution analyses\ndifferent calibration strategies for planar bundle-invariant interfaces. To evaluate the effects of\nimplicitly modelling the refractive effects within bundle adjustment, synthetic error-free datasets\nare simulated. The behaviour of interior, exterior, and relative orientation parameters is analysed\nusing synthetic datasets free of underwater imaging effects. A shift of the camera positions of 0.2%\nof the acquisition distance along the optical axis can be observed. The relative orientation of a\nstereo camera shows systematic effects when the angle of convergence varies. The stereo baseline..............
