【摘要】 地理信息系统(Geographic Information System)经过四十多年的发展,无论是在理论研究上还是具体的工程应用上,都取得了巨大的进步,并随着社会应用的需要不断深入到各个行业领域中。在应用范围上,GIS从最初为部门服务发展到政府应用、地区应用、国家应用,甚至全球应用,“数字地球”也正是在空间信息三大关键技术GIS、GPS、RS的发展和融合基础上提出的。计算机技术的不断发展,以及人们对相关技术理论的努力探索研究,都使得GIS以前所未有的速度发展,相继出现了基于网络技术的WebGIS,基于COM的组件GIS,基于嵌入式技术的嵌入式GIS等分支体系。随着地理信息系统在掌上电脑、智能手机、笔记本等移动终端上的应用,LBS(Location Based Service)以及无线网络的蓬勃发展,推动了地理信息系统向移动应用方向发展,Mobile GIS随之诞生,这使得任何人随时、随地的获得地理信息服务成为现实,而且可以预见,随着理论、技术的进一步发展,Mobile GIS的应用深度与广度会更加激动人心。 本论文的研究目的是通过地理信息系统、全球定位技术、嵌入式技术的结合,研究开发基于Mobile GIS的车辆导航系统,该系统除了具有传统的电子地图显示、查询、分析等功能外,还利用现在迅速兴起的GPS定位技术,实现车辆实时定位和智能导航功能。 论文从智能车辆导航系统在国内外研究和发展的状况出发,阐述了车辆导航系统的发展前景,分析了Mobile GIS发展状况、关键技术及其应用,探讨了进行基于Mobile GIS车辆导航系统开发研究的意义,其研究对车辆导航系统的开发在理论与方法上具有一定的借鉴价值。论文对原型系统在总体结构、功能模块等方面进行了设计,通过嵌入式开发语言Microsoft Embedded Visual C++开发了系统的主要功能模块,对开发过程中所遇到的问题进行了研究,提出了相应算法和解决方案,最终实现了集电子地图、GPS移动定位、路径规划、智能导航等多项功能于一体的车辆导航系统MobileMap。 论文研究主要涉及嵌入式开发、GIS与GPS的系统集成,横跨电子地图设计、移动计算、定位导航等技术以及计算机科学和空间信息科学等领域。更多还原

【Abstract】 Through more than 40 years’development, GIS (Geographic Information System) has made the huge progress, regardless of in the fundamental research or in the concrete project application, And utilized unceasingly in each professional fields along with the social application needs. In application scope, GIS serves for the department at early stage, and later for the government application, the local application, the national application, even global application. "The Digital Earth" also is brought up on the bases of three essential spatial information technologies’ (GIS, GPS, RS) development and the integration. Computer technology development, As well as people’s diligently exploration and research on relative technology and theory, All cause GIS develop by the unprecedented speed, WebGIS, COM GIS and Embedded GIS, Appeared one after another. Along with GIS apply on mobile terminal, smartphone and notebook, As well as LBS (Location Based Service) and the wireless network’s vigorous development, Impelled GIS to develop to the mobile application, Mobile GIS is born, This causes anybody at anytime, anywhere to obtain the geographic information service become the reality, Moreover may foresee, Along with theory and technical further development, The Mobile GIS application’s depth and the breadth can be more exciting.The paper’s goal is to develop a Vehicles Navigation System based on Mobile GIS through the integration of GIS, GPS and Embedded Technology. This system has function of traditional Electronic Map display, inquiry and analysis, also realizes the vehicles real-time locating and the intelligent navigation function relying on the GPS localization technology.The paper introduces the intelligent Vehicles Navigation System’s research and the development condition in the domestic and foreign, Elaborate the prospects for development of the Vehicles Navigation System, Analyzes Mobile GIS development condition, the essential technology and its application, Discusses the significance of developing and studying the Vehicles Navigation System based on Mobile GIS. Its research has the certain model value to the Vehicles Navigation System development in the theory and the method. The paper has designed the prototype system’s overall structure, function module and so on. With the embedded development language Microsoft Embedded Visual C++, the author develops main function modules of the system, Researches the problems in the processing of implementation, Proposes the corresponding algorithm and solution. Finally Vehicles Navigation System which integrates the Electronic Map, GPS mobile localization, the route planning, the intelligent navigation functions——MobileMap has been realized.The paper mainly involves Embedded Development, GIS and GPS’s integration, Stretches across Electronic Map design, mobile computation, localization, navigation technologies and so on, As well as Computer Science and Spatial Information Science.更多还原
