Abstract

Taking into account the complexity of the terrain, the triangulation irregular net thinning method is used to obtain the characteristic spot of multi-beam sounding data, and the advantages of multi-diagonal exchange algorithm are integrated and improved, and the improved constraint algorithm is used to embed the isobaths to construct the seabed DEM. Experiments indicates that the method can effectively identify the characteristic spot, and the thinning method based on characteristic spot and isobath constraint can effectively construct the seabed DEM with high precision and high resolution.
