【摘要】 本论文的研究工作主要是将GIS技术引进汽车导航系统，使汽车导航系统除具备一般的定位功能外，利用GIS强大的空间分析能力，可以提供实时显示汽车位置、信息查询和提示及路径规划等功能，起到了有效避让交通拥挤，保障交通安全，快速查找目的地位置的效果。 本文按照汽车导航系统的开发流程，逐步提出所涉及的关键技术并提出相关解决方案。探讨了GIS电子地图的数据组织；基于点边拓扑关系的最优路径的搜索；GPS数据处理和接口技术；及采用ComGIS开发模式开发导航地图软件的程序实现等相关内容。 对路径规划和车位显示问题进行了重点研究和设计。研究基于GIS的最优路径搜索算法，对GIS关系表的结构提出了信息完备性的要求。良好的表结构可减少交通网络的方向性、转向约束、权值约束等给最佳路径搜索带来的复杂性。不同系统的最短路径问题只需用可视化方法修改相应数据表中存储的拓扑数据，而算法的求解过程保持不变。并考虑了实时交通信息的变化对交通网络拓扑关系和最优路径搜索的影响。在探讨汽车定位时阐述了GPS／DGPS定位技术；如何将GPS／DGPS提供的定位信息输入计算机；GPS接收机与计算机以及与导航软件的接口问题；利用GPS／DGPS提供的定位信息，经坐标变换并采用地图匹配技术将车位准确地显示在道路上。 最后开发了实验系统，相关算法原理和关键技术得到了正确性验证。更多还原

【Abstract】 Introduce the navigation system of automobile in application that the research work of this thesis lays particular emphasis on GIS technology mainly, Make the navigation system of automobile utilize GIS strong space and analyse ability besides possessing the general localization function, Can help the driver to show and inquire about and briefed on and choose etc. in the optimum route the automobile position, information in real time , It gets up and finish arriving and avoid traffic jam of letting effectively it ensures traffic safety look for purpose result who status put fast.This text puts forward the key technology involved and put forward the relevant solution progressively according to developping the order of the electronic map system of figure. It probe into organize at what has been lasted map GIS datas, From ones not topological for the the relation one for optimum the searches of the routes , GPS between data processing and interface technology, adopt ComGIS develop mode develop and navigate map the implementation technique relevant content s of softwareAnd the parking stall show that carries on key research and designed in question to plan the route. It studies based on GIS optimum routeses search for algorithm propose information the requests of completeness to GIS relation the structures of form. Good form structure reducible traffic the directionality, turn to , right value finish retraining and search for the complexity brought restraint to the best route s of networks. A different and systematic one hold up foot-path need with visual to take method store topological data by modification corresponding data lists only by issue most,Algorithm ask and solve course keep and become..The influence searched for to the topological relation of network of the traffic and optimum route in change of the real-time traffic information that and has considered. In probing into automobile explain GPS/DGPS make a reservation technology, how import to the computer localization information who GPS/DGPS offer when making a reservation, GPS receiving set and computer and navigate the interface problems of the software; The localization information utilizing GPS/DGPS to offer, is vary and adopted the map to match technology and show the parking stall on the road accurately by the coordinate. Having developed the experimental system at last, relevant algorithm principle and key technology got exactness verification.更多还原
