【摘要】：地面站导航电子地图是操作员用来监控无人驾驶装备的唯一平台,也是进行线路规划和自主决策的重要信息源。现有的导航电子地图一般存在价格昂贵、对高程数据支持不足以及依赖互联网等缺陷。本文提出了一种新的基于OpenStreetMap的地面站导航电子地图实现方法。首先,利用原始OSM数据搭建地图瓦片服务后台;然后将90 m SRTM高程数据处理成地形阴影和地形颜色渐变栅格文件;针对每个栅格文件,在瓦片服务后台的样式配置文件中添加相应图层并定义其渲染格式;最后,在地面站软件中实现地图客户端模块,向瓦片服务后台请求瓦片,并显示在地面站界面上。利用该方法实现的地面站导航电子地图可以提供0~18个缩放级别的中国范围的数据,显示0~13个缩放级别的立体地形地貌,并且无需互联网支持。本文使用该方法实现了某型无人机的地面站导航电子地图模块,并成功应用该无人机仿真系统。
[Abstract]:Earth station navigation electronic map is the only platform for operators to monitor unmanned equipment, and it is also an important information source for route planning and autonomous decision-making. The existing navigation electronic maps generally have the disadvantages of high price, insufficient support for elevation data and dependence on the Internet. In this paper, a new implementation method of earth station navigation electronic map based on OpenStreetMap is proposed. Firstly, the original OSM data is used to build the map tile service background, and then the 90m SRTM elevation data is processed into the terrain shadow and terrain color gradient grid file. For each grid file, add the corresponding layer to the style configuration file of the tile service background and define its rendering format; Finally, the map client module is implemented in the earth station software, and the tile is requested from the tile service background and displayed on the interface of the earth station. Using this method, the electronic map of earth station navigation can provide data of 0 ~ 18 zooming levels in China, and display 0-13 zooming levels of stereoscopic landforms without Internet support. This paper uses this method to realize the navigation electronic map module of a ground station of a UAV, and successfully applies the UAV simulation system.
