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.

Abstract: The present invention relates to a method for asynchronously storing massive data generated during high speed video measurement, the method including the following steps: step (1), constructing a high speed video measurement hardware model; and step (2) realizing asynchronous I/O real-time storage in a high speed solid state disk on the basis of Windows core programming. Compared with the prior art, the present invention solves the problems of incompleteness or frame drop during real-time storage of massive data, and realizes real-time and lossless storage of massive high speed data.
