Method for producing a georeference model from bathymetric data

摘要

Creating a georeference model from input bathymetric data includes defining a search limit grid and establishing a geometric model. An iterative RANSAC process is used to fit bathymetric data calculate the geometric model for each cell of the grid. Points that are too far away from the geometric model are removed, and geometric models are recalculated. The compiled geometric models are used as the georeference model. In further embodiments, the georeference model can be smoothed to remove boundaries between cells. Other embodiments provide for using the georeference model for navigation and data transmission.
