ABSTRACT
The study aims to explore the safety of ship navigation, in view of 3D (three-dimensional) visualization of navigation mark and of seabed topography. The main contribution lies in two aspects. One is for 3D visualization of aids to navigation, the other is for 3D visualization of seabed topography. From the electronic chart and S-57 data, the shape, color, top mark and luminous characteristics of the navigation mark are extracted. Compared with the previous methods, the simulation on Visual Studio shows that the 3D scene can provide more visual and clear information to the ships. The depth data of electronic chart is extracted and processed, and then the irregular triangular grid is constructed by Delaunay triangular grid method. The two aspects of study, mainly use the corresponding data information to complete the goal of building 3D scene automatically and quickly.
