【摘要】：随着“智慧城市”的推进和地理信息行业的发展,地图三维化,数字化,智能化的趋势也在日益增强。目前我国很多地方和单位,如高校校园,工业园区等都在进行区域三维数字地图的建设工作。三维数字导览地图是运用3S技术(全球卫星导航系统GPS,遥感RS,地理信息系统GIS)对某个特定区域进行数字化地图信息采集,并结合虚拟现实技术、BIM建模技术(Building Information Modeling)等对区域内所有建筑、道路、环境进行数字化,三维化,再运用GIS平台建立各个地物信息的属性数据库,可以实现属性信息查询、路径导航分析等功能的智能化新型地图。以目前高校校园的地图为例,很多高校建立的三维地图是以固定45°倾角基于浏览器展示的2.5维地图,严格意义上说这种地图并非真正的三维地图。重新开发可查询、定位、自由漫游的三维地图系统平台又将耗费巨大的人力物力,对于建设小范围的数字化三维地图来说可谓是过于铺装浪费。因此在一个成熟的三维GIS平台基础上开发一套独立的系统是一个折中的选择。本论文主要内容可分为两部分,其一是对三维建模技术进行分析对比研究,结合利用3S技术现场实测的区域数字地形图,选用目前较为热门的几种三维建模软件进行区域DEM的建立及区域三维模型的建立。其二是选用Google Earth作为三维GIS平台,利用MFC技术调用Google Earth COM API接口,将建立好的三维模型与GIS平台相融合,并结合制作相关KML文件进行总体封装,从而完成一个可移植的独立的区域三维地图导览系统。通过建立区域三维地图导览系统,该区域地图可实现数字化和真三维化,并可在Google Earth三维GIS平台上实现360°自由漫游、路径规划、区域定位、属性查询、GIS分析等一系列功能。
[Abstract]:With the advance of "Smart City" and the development of geographic information industry, the trend of 3D, digitization and intellectualization of map is increasing day by day. At present, many places and units in our country, such as university campus, industrial park and so on, are working on the construction of regional 3D digital map. 3D digital navigation map is to use 3s technology (GPS, RS, GIS) to collect digital map information for a specific area. With the help of virtual reality technology, (Building Information Modeling) and so on, all the buildings, roads and environments in the area are digitized and three-dimensional, and then the attribute database of each feature information can be established by using GIS platform, which can realize the query of attribute information. Path navigation analysis and other functions of intelligent new map. Taking the map of university campus as an example, many colleges and universities have established the three-dimensional map which is based on the browser display with fixed 45 掳inclination angle. Strictly speaking, this kind of map is not a true three-dimensional map. Redeveloping the 3D map system platform which can query, locate and roam freely will cost a lot of manpower and material resources, so it is too extravagant for the construction of small scale digital 3D map. Therefore, it is a compromise choice to develop an independent system based on a mature three-dimensional GIS platform. The main content of this paper can be divided into two parts. One is to analyze and compare the 3D modeling technology, combining with the regional digital topographic map measured by 3s technology. Several popular 3D modeling software are used to build regional DEM and regional 3D model. The second is to select Google Earth as the three-dimensional GIS platform, using the MFC technology to call the Google Earth COM API interface, to integrate the established 3D model with the GIS platform, and to make the related KML files for overall encapsulation. In order to complete a portable independent regional 3D map navigation system. Through the establishment of a regional 3D map navigation system, the regional map can be digitized and true three-dimensional, and a series of functions such as free roaming, path planning, regional location, attribute query and analysis can be realized on the Google Earth 3D GIS platform.
