【摘要】 车辆导航系统是应用地理信息系统(Geographic Information System-GIS)技术构造导航电子地图,并结合全球定位系统(Global Positioning System-GPS)技术,对车辆的行车位置、速度、方向以及周围的详细地理环境,进行实时监控和查询,对最优路径进行计算和规划,以帮助驾驶员了解车辆目前的位置和状况,使驾驶员能在陌生的地理环境中,准确地选择路线,从而快速、安全地到达目的地。 本论文分析了车辆导航系统的国内外发展现状,论述了GIS和导航电子地图在车辆导航系统中的应用情况,在此基础上,对基于GIS车辆导航系统的基本实现方法进行了研究,对车辆导航系统的功能进行了设计,并予以实现。 论文首先分析了导航电子地图的理论基础、导航电子地图的特点、导航电子地图建立的标准和论文所采用电子地图的表示方法;在这些理论基础的指导下,对导航电子地图作了充分的设计,按照满足导航系统应用的目标,建立了符合需求的导航电子地图数据库,为导航系统的功能应用打下了坚实的基础。 论文对常用的GIS软件开发方式进行了分析和比较,根据软件开发进度、开发成本、开发效率,提出了采用基于GIS组件的集成二次开发方式。在充分考虑GIS平台选择的各个因素,包括:GIS平台软件的公司实力、具备空间分析的能力、开放性的二次开发环境、具有的代表性和方向性、合理的性能/价格比,再考虑到现有的资源条件,本论文选择了北京超图公司的SuperMap Objects控件,同时对论文所用的SuperMap Objects控件进行了详细分析,为车辆导航系统的开发奠定了牢固的基础。 论文分析了车辆导航系统的功能需求,以解决“系统可以干些什么”的重要问题;分析系统的组成部分,提出了系统的总体设计方案,包括平台的总体设计、软件开发平台的建立,对人机交互界面和系统的各个功能模块作了详细的设计。 论文设计实现了车辆导航系统的基本功能,包括:对导航电子地图的放大、缩小、图层控制等基本操作;导航图的鹰眼查询、图属互查以及地点查询等功能;在导航电子地图上显示车辆的实时位置;对更多还原

【Abstract】 Vehicle-Navigation Syslem(VNS) is a kind of technology to implement the real-time control and query to the vehicle information, such as location, speed, course and surrounding geographic information etc, and provide an optimum missions and routes for the drivers. Nowadays VNS is more and more dependent on the integration use of Global Posi t ioning System (GPS) and Geographic Information System (GIS) technology, e.g. geo-spatial information acqui ring and underlying navigation map constructing. With the help of VNS, drivers can easily identify the vehicle related location information as well as the traffic information timely. In this case it would be possible to pick out an idea routes to the destination rapidly and safely even in the fully unfamiliar environment.The thesis reviews the history of VNS and presents an introduction of VNS development currently. Through the illustration of the practical application of GIS based navigation map in VNS. The works of this thesis are as the below:The basic theory analysis of the navigation map and the expression methods of the digital map adopted are carried out and studied respectively, such as the features of digital map and the standards of constructing navigation map. Then, the detail design on navigation digital map as well as the database to meet the VNS’ requirements is accomplished.The common development methods of GIS application are analyzed and compared in the thesis. The author proposes adopting integrated secondary development way based on GIS component. Considering the software development schedule, cost and efficient, the author adapts SuperMap Objects of Beijing SuperMap Corp for software development after taking fully account of various factors involved, including the selection of GIS platform vendors, the vendor’ s qualification, function of spatial analysis, opening of secondary development environment, performance/price ratio as well as available resource. Meanwhile, the author performs a thorough studyon the Super.Vlap Objects, laying a sol id foundation for the development of VNS.The functional requirements of VNS answer the key question of what the system can do. Through analyzing structure of the system, the overall design scheme is promoted which comprises overall design of platform, the establishment, of software development platform, and detail design on the interactive interface and each functional module.Some navigation functions have been realized, including the basic functions, I’or example, zooming out and zooming in of navigation map and layer operation. Some other functions such as hawk eye query of navigation map, map attribute interactive query, location query and so on . The system possesses features showing the real-time location of vehicle in navigation map and selectively, replaying the trace of vehicle and analyzing of the optimum routes from the beginning to the destination. The advantages of the system include compact structure, reliability of function, fast application response and easy expansibility.Finally, some useful conclusions and suggestions for further studies are summarized and remarked.更多还原
