摘要
开发了嵌入式车载导航产品V-NAV1.0,用于公路网导航系统,解决了其计算数据量大,道路规划和语音导航算法复杂,实时性要求高等问题.针对嵌入式系统计算资源、存储资源有限,约束条件多,实现了嵌入式车载语音导航系统中地名查询、汉字查询、近期查询等多种目的地输入,给出了数据可视化表示方法.在实时路径计算的基础上实现了智能语音导航,并辅以三种路口导航图片提示方式,同时显示目标距离并将前方路口距离等信息作为车辆导航的补充.设计的导航产品V-NAV 1.0满足实用要求.
Embedded system is restricted with many computing and memory resources. Navigator needs process a great mount of data sets including national seven grades roads net, using complex real time algorithms of routes programming and navigation based on Audio supporting. Destinations can be input according to names, addresses and recent results. Map data visualization method is presented. Navigation based on routs computing is accomplished through audio reminding and three road cross pictures. VNAV 1.0 has been proved to have uniform functions, convenient operation and satisfy real time demand.
