【摘要】 随着互联网地图和LBS(Location Based Service)等地理信息应用的发展,室内导航正以其弥补室外地图应用局限、拥有潜在的庞大用户群体、具有创新的技术与应用需求驱动等众多优势,而被产业界和学术界所普遍关注。以Google和Nokia等为主的在线电子地图厂商和手机终端厂商,更是纷纷推出相关的室内导航软件及应用。大型购物中心作为城市人群聚集的重要载体,开展其室内导航相关的研究及应用开发,不仅具有应用典型性,同时研究成果更容易推动形成相关的室内导航专业化产品。针对当前室内导航应用中地图示意、增强现实感差、模型简单、缺乏路径规划等缺陷,结合未来室内导航应用的发展趋势,考虑到GIS从室外到室内所面临的应用快速发展与理论、技术方法滞后的矛盾,论文的主要研究内容与取得成果如下：(1)通过对大型购物中心室内空间结构及其功能的分析,结合室内导航应用需求,研究并建立了包含4个大类、14个中类和85个小类在内的地理要素分类体系；借鉴CityGML,研究并设计了以楼块、楼架和楼层为主的室内三维导航多细节层次。(2)基于大型购物中心室内三维导航地理要素分类与多细节层次,从要素、网络和几何的视角研究并建立了室内三维导航地理数据概念与逻辑模型；基于GML和CityGML规范及其应用模式创建规则,设计并制定了室内三维导航地理数据模型XML模式。(3)以南京新城市广场为试验对象,研究室内三维导航数据的采集与建模方法,设计三维导航算法及路径规划流程,通过开发试验系统,对本文提出的室内三维导航模型进行验证。更多还原

【Abstract】 With the development of the Internet map, LBS (Location Based Service) and other geographic information applications, indoor navigation has been widespread concerned in industry and academia for it compensate for the limitations of outdoor map applications, has a large potential user groups, and driven by nnovative technology and Application requirements.Online electronic map vendors and mobile terminal vendors such as Google and Nokia, have been offering indoor navigation software and applications. For shopping malls are important carriers of the city crowd, to carry out the research on indoor navigation and the application development, not only has the typicality of application, but also easier to promote the formation of specialized products of indoor navigation.For defects in current indoor navigation applications such as map can only be indicate, sense of reality is poor, the model is too simple, and path planning is lack, combined with the development trend of indoor navigation applications in future, GIS from outdoor to indoor will face to contradictions between the rapid development of applications and lag theory, technology and methods.The main research content and achieve results as follows:(1) Analysis of the Indoor spacial structure and function of a shopping mall; combined with the indoor navigation application requirements, research and establish a geographic feature classification system which contains 4 categories,14 classes and 85 subclasses;drawing CityGML, research and designindoor three-dimensional navigation levels of detailbased on block, frame and floor.(2) Based on geographic feature classification and levels of detail of indoor 3D navigation ofshopping mall, from the perspective of the elements, network, and geometric research and establish geographic data conceptualmodel and logical model of indoor 3D navigation; create rules based on GML, CityGML specification and its application models, to designand develop the XML schema of indoor 3D navigation model of geographic data.(3) The paper selects Nanjing New-town Plaza as the experimental object, research indoor 3D navigation data collection and modeling methods, design algorithm and path planning processof 3D navigation, to verify the proposed indoor 3D navigation model through the development of the experimental system.更多还原
