项目摘要

Based on features on digital map, such as building contour (building polygon) and road polyline, we are proposing the system to generate 3-D Urban Model automatically. A 3-D urban model is an important information infrastructure that can be utilized in, several fields, such as landscape evaluation, urban planning, disaster prevention simulation, tourism, and many other business practices. In addition, disclosure of information about public projects to the public in order to encourage their participation in city planning is a new application area where a 3-D urban model can be of great use. When a real urban world is projected into 3-D virtual space, buildings are major objects in this space. To realize a 3-D urban model, it is important to generate building models efficiently. However, in order to realize 3-D building models, enormous time and labor has to be consumed to acquire the spatial data and to design the models. For example, when manually modeling a house with roofs by Constru … More ctive Solid Geometry (CSG), one must follow these laborious modeling steps : 1)generation of primitives of appropriate size, such as box, prism or polyhedron that will form parts of a house 2)boolean operation among these primitives to form the shapes of a roof and a house body 3)rotation of parts of a house 4)positioning of parts of a house 5)texture mapping onto these parts.In order to automate the steps mentioned above, we proposed the GIS and CG integrated system that automatically generates 3-D building models from building polygons on a digital map stored by GIS. Most building polygons have right angles (orthogonal polygon) and varies in the number of the vertices. The algorithm for dividing orthogonal polygon into a set of rectangles is developed. After dividing, the integrated system is placing CG primitives i.e. building parts on these polygons to form a 3-D building model. The system automatically generates a 3-D urban model so quickly that it meets the urgent demand to realize another alternative plan.Also, we propose the automatic generation system to produce 3-D water way model from a center line of water way stored and controlled by GIS. The water way that restores native habitat and its natural meander plays an important role for the revitalization of a city. The water way improvements project aims to provide stable, maintainable flood control while environmentally restoring sections of water way to their natural meanders and adding amenities and recreational opportunities along the water way. In these projects, 3-D water way model will serve as planned or proposed common image among citizen, neighborhood, designers and officials. However, in order to realize 3-D water way model, enormous time and labor have to be consumed to design bank, shore, vegetation and topographical features. In our research, we developed the system to generate 3-D water way models, automatically by integrating GIS and CG. Less

基于数字地图上的特征，例如建筑物轮廓（建筑物多边形）和道路折线，我们建议系统自动生成3D城市模型。 3D城市模型是重要的信息基础设施，可用于景观评估、城市规划、防灾模拟、旅游和许多其他商业实践等多个领域。此外，向公众披露公共项目的信息以鼓励他们参与城市规划是一个新的应用领域，3D 城市模型可以发挥很大作用。当真实的城市世界被投影到 3D 虚拟空间时，建筑物是该空间中的主要对象。为了实现 3D 城市模型，有效生成建筑模型非常重要。然而，为了实现3D建筑模型，必须花费大量的时间和劳动力来获取空间数据并设计模型。例如，当通过构造实体几何 (CSG) 手动建模带有屋顶的房屋时，必须遵循以下费力的建模步骤：1) 生成适当尺寸的图元，例如将形成房屋部分的盒子、棱柱或多面体 2) 这些图元之间的布尔运算以形成屋顶和房屋主体的形状 3) 房屋各部分的旋转 4) 房屋各部分的定位 5) 纹理映射为了自动化上述步骤，我们提出了 GIS 和 CG 集成系统，该系统可以根据 GIS 存储的数字地图上的建筑多边形自动生成 3D 建筑模型。大多数建筑物多边形都有直角（正交多边形），并且顶点数量各不相同。开发了将正交多边形划分为一组矩形的算法。分割后，集成系统将 CG 图元（即建筑部件）放置在这些多边形上，形成 3D 建筑模型。该系统自动生成3D城市模型的速度非常快，满足了实现另一个替代方案的迫切需求。此外，我们提出了自动生成系统，从GIS存储和控制的水道中心线生成3D水道模型。恢复原生栖息地的水道及其自然蜿蜒的河道对于城市的复兴发挥着重要作用。水道改善项目旨在提供稳定、可维护的防洪，同时将水道部分恢复到自然蜿蜒的环境，并增加水道沿线的便利设施和娱乐机会。在这些项目中，3D水道模型将作为公民、社区、设计师和官员计划或提议的共同形象。然而，为了实现3D水道模型，需要花费大量的时间和人力来设计岸、岸、植被和地形特征。在我们的研究中，我们开发了通过集成 GIS 和 CG 自动生成 3D 水道模型的系统。较少的
