【摘要】：进入二十一世纪以来，随着我国城市化的快速发展，使得城市内部的土地资源变得越来越紧缺，而土地资源的利用，也向着多层次、高利用率的立体化方向发展。传统的二维地籍管理因自身存在的局限性，已经无法满足现今社会发展的需要，是以现阶段的地籍管理方式正慢慢的向着三维地籍管理模式转变。因此，三维地籍管理就成为当前土地研究的重点。作为三维地籍数据库场景搭建的重要组成部分，三维模型在各个方面起着重要作业。三维建筑物模型代替传统的二维平面图，可以直观表现出地籍与宗地的相互关系；三维界址模型可以准确的显示出三维空间内的宗地权属关系。本文以长春市三维地籍数据库建设的契机为切入点，对于构建三维数字城市的主要环节的三维仿真模型进行了研究。以航空摄影测量、激光点云扫描、倾斜摄影技术等建模方法，配合外业实地照片采集，应用3D Max、Photoshop软件将两者相结合，建成真三维仿真场景，同时构建GIS数据搭载平台，将DOM正射影像数据、DEM数字高程模型、界址点线模型、宗地体模型、交通设施模型、辅助设施模型等多种数据类型统一结合成三维地籍信息系统，为其他省市的相关项目起了借鉴作用。
[Abstract]:Since the 21 century, with the rapid development of urbanization in our country, the land resources in cities become more and more scarce, and the utilization of land resources is also developing towards the direction of multi-level and high-utilization. The traditional two-dimensional cadastral management, because of its own limitations, has been unable to meet the needs of the current social development, is the current cadastral management mode is slowly changing to three-dimensional cadastral management mode. Therefore, the three-dimensional cadastral management has become the focus of land research. As an important part of 3D cadastral database scene building, 3D model plays an important role in all aspects. Three-dimensional building model can directly show the relationship between cadastral and ancestral land, and 3D boundary model can accurately show the relationship between land ownership and land ownership in three-dimensional space instead of the traditional two-dimensional plan. Based on the opportunity of constructing 3D cadastral database in Changchun, this paper studies the 3D simulation model of the main link of 3D digital city. With aerial photogrammetry, laser point cloud scanning, tilt photography technology and other modeling methods, combined with field photo collection, 3D Max Photoshop software will be used to build a true three-dimensional simulation scene, at the same time to build a GIS data loading platform. The digital elevation model of Dem, boundary point line model, terrain model, traffic facilities model, auxiliary facility model and other data types of DOM orthophoto image data are integrated into a three-dimensional cadastral information system. For other provinces and cities related projects play a reference role.
