Abstract: The present invention relates to a multi-medium imaging analytic method for underwater medium surface position compensation. The method is used for compensating a medium surface position based on refraction theorem, specifically comprising: acquiring a refractive index and a thickness of each medium, computing a medium surface position compensation value according to an incident angle, and obtaining a virtual medium surface as a new medium surface to convert a multi-medium imaging analysis model into a double-medium imaging analysis model. Compared with the prior art, the method has the advantages of high feasibility, excellent stability, sub-millimeter accuracy, and the like.
