摘要
The invention discloses a multi-beam bathymetric chart construction method based on submarine digital depth model feature extraction. The method comprises the steps of: constructing a DDM (Digital Depth Model) based on raw multi-beam echo soundings; establishing a slope and second derivative composite model based on the DDM; extracting feature points based on DDM sub-blocks; querying the multi-beam depth based on the feature points; constructing the multi-beam bathymetric chart based on layers.
