摘要
The function of dynamic track drawing realized in the ship monitoring system. Based on the function, we could draw the sailing tracks dynamically according to the ship＇s orientation. Two kernel algorithms are involved during the system developing process, i.e. the algorithms of angular deflection and distance interval value. The practice of system development shows that the proper application of these two algorithms has good effect＇in the visualization of sailing track.
船舶监控系统中实现了船只航迹线的动态绘制,系统能够根据船只航行方向动态显示航行轨迹,程序开发过程中涉及到偏转角度算法和距离插值两个核心算法,系统开发实践表明,这两个算法的合理应用在航迹线可视化表现方面取得了良好的效果。
