基于WinCE的无人机嵌入式地面站GIS显示优化

摘要

针对无人机嵌入式地面测控站系统资源和性能的局限性，研究了基于WinCE系统的嵌入式GIS地图的显示过程和原理，分别从动态和静态2个方面提出了嵌入式平台下优化无人机GIS地图应用的软件和硬件方法，静态方面在于优化地图文件的转换和读取以适用于嵌入式平台，动态方面在于将需要动态更新和添加的内容进行算法上的裁剪或精简以达到快速显示的目的。测试结果表明，这些优化方法有效地减少了嵌入式WinCE系统下GIS地图资源占用，提高了GIS地图显示效率，也为其他平台GIS地图的显示优化提供了参考。%In view of the limitations of resource and performance of UAV embedded ground control system,this paper studies the display process and principle of embedded GIS map based on WinCE system. The software and hardware methods of UAV GIS map application optimization based on embedded platform from static way and dynamic way respectively.The static way is used to convert the huge map file to meet the demand of embedded system. The dynamic way is used to cut or reduce the dynamic update and increase contents for fast display.The test results show that the optimization methods can reduce the usage of system resource of embedded GIS map in embedded WinCE system and improve the display efficiency of GIS map. It can also provide reference for GIS map display optimization of other platform.
