Abstract
A method and system for positioning and correcting visual data by seafloor topographic profiles are provided. The method includes: offsetting the water-depth profile of the target survey line equidistantly in a grid layer of a target area to make profiles generated after the offsetting traverse the grid layer of the target area, and obtaining offset data sequences corresponding to the water-depth profile of the target survey line; drawing offset topographic profiles based on offset data of the offset data sequences corresponding to the water-depth profile of the target survey line; calculating a profile similarity between the water-depth profile of the target survey line and each of the offset topographic profiles by using a dynamic time warping (DTW) algorithm; and selecting a geographic location of one of the offset topographic profiles with a largest profile similarity as an actual geographic location of a water-depth profile of a seafloor visual survey line.
