摘　　要：设计基于多媒体技术的船舶航行轨迹实时显示系统,通过充分分析该系统的功能需求后,设计基于FPGA的船舶导航雷达回波采集模块,利用该模块获取船舶导航雷达的回波,再通过卡尔曼滤波算法从船舶导航雷达回波内获得船舶航行轨迹后,再使用多媒体技术内的3Dmax技术建立船舶和其航行环境模型,将船舶航行轨迹导入到该模型后,通过实时显示模型驱动HMI显示屏为用户呈现船舶航行轨迹可视化画面,实现船舶航行轨迹实时显示。实验结果表明,该系统具备良好的雷达回波采集能力,可有效获得船舶航行轨迹的经纬度,并可以可视化画面方式呈现当前船舶的航行轨迹,应用效果较好。Design a real-time display system for ship navigation trajectory based on multimedia technology. After fully analyzing the functional requirements of the system, design a ship navigation radar echo acquisition module based on FPGA. Use this module to obtain the echo of the ship navigation radar, and then use the Kalman filtering algorithm to obtain the ship navigation trajectory from the ship navigation radar echo. Then, use 3Dmax technology within multimedia technology to establish a model of the ship and its navigation environment, After importing the ship's navigation trajectory into the model, the real-time display of the ship's navigation trajectory is achieved by driving the HMI display screen to present a visual image of the ship's navigation trajectory to the user. The experimental results show that the system has good radar echo acquisition ability, can effectively obtain the longitude and latitude of the ship's navigation trajectory, and can visually display the current ship's navigation trajectory, with good application effects.
