Abstract

In this paper, the marine situation plotting system combined with normal trajectory model is exploited by adopting object-oriented design method and dynamic link library technology. The system is implemented with heavy emphasis on simplicity and usability. The system has the functions of situation display, plotting and trajectory extraction. The trajectory shrinkage optimization method of normal trajectory model is used to optimize a large number of tracks. Then the DBSCAN algorithm is carried out to cluster the optimized data to get the normal trajectory model, which can contribute to the plotting function. The plotting function includes point plotting, line plotting, and surface plotting. Users can select the plotting operation on the floating panel. The system can adaptively select the corresponding ship icon according to the scale of chart. Color-coded situation displays are used for different types of ships, which improve the situational display and overall awareness. Additionally, users can operate the mouse on the situation map for ranging and area measurement. The experimental results show that the system has good operability and usability.
