| Abstract: | According to navigation requirements of visual angle and geometric accuracy and image reality of underwater topography, using theory of three-dimension realistic terrain, this paper introduced two methods for generating Delaunay triangulation of topography based on chart contour and fathom lines. Through plane scattered data triangulation without interpolating point, terrain modeling of Three-dimension Navigation Display System was presented based on ECDIS and AIS. The applications of this system would greatly improve the security of navigation and the validity of shore-based real-time supervision and control. |
