基于Web墨卡托投影的导航电子地图设计

针对目前无人机地面测控站导航模块的局限,提出了基于Web墨卡托投影原理的导航电子地图的设计方案,使用ImageStone类库简化了电子地图的制作,并实现了电子地图的绘制、平移及缩放功能；在此基础上完成了航迹规划、实际飞行航线的实时显示以及航线保存等功能,大大提高了地面站的导航地图与导航信息融合显示的实时性；经过无人机仿真系统的测试,验证了方案设计的合理性和可行性,该导航电子地图能够高效、准确地完成各项导航任务。

Design of Navigation Electronic Map Based on Web Mercator

Aimed at the restricted navigation module of unmanned aerial vehicle(UAV) ground control station(GCS), this paper designed a navigation electronic map based on Web Mercator. This module simplified the electronic map making by using ImageStone class library, and achieved the function of map plotting, translation, and zoom. On this basis, the paper completed route planning, real-time display of the route, saving the data and etc. The design of the navigation electronic map greatly increased the real-time display in the fusion of electronic map and navigation information. The test of UAV simulation system verified the rationality and availability of the design, the navigation electronic map can finish the navigation task efficiently and accurately.
