摘　　要：利用当下流行的渐进式JavaScript框架Vue和Leaflet地图组件,构建一套稳定、易用、用户体验好的多功能北斗定位可视化监控平台。从前端软件架构以及前后端交互机制出发,通过将北斗设备获取的原始WGS84坐标转换为国测局GCJ02坐标,实现了北斗终端的实时监控、历史轨迹回放等功能;针对历史轨迹回放中存在的位置点偏移与路径折线的问题,引入路径匹配和轨迹插值算法,提高了历史轨迹回放的准确性与运动轨迹的平滑性。Using the progressive JavaScript framework Vue and leaflet map components to build a stable,easy-to-use,user-friend⁃ly and multi-functional Beidou Positioning visual monitoring platform.Starting from the front-end software architecture and the front-end interaction mechanism,transforms the original WGS84 coordinates obtained by Beidou equipment into GCJ02 coordi⁃nates of the National Bureau of survey,and realizes the functions of real-time monitoring and historical track playback of Beidou terminal.Aiming at the problems of position point deviation and path broken line in the playback of historical trajectory,path matching and trajectory interpolation algorithms are introduced to improve the accuracy of historical trajectory playback and the smoothness of motion trajectory.
