基于规则的数字校园三维场景建模方法研究

摘要

This paper discusses what from the 3D modeling data access to the construction of terrain and surface features model, re-search the method for building 3D GIS scene, and select XX as the research area, including the data acquisition and processing, the matching of terrain and surface feature, then build model of the 3D scene based on rules including buildings, roads, playground, trees, etc.And at last exported to the Geodatabase.This method based 3D scene modeling is applied to the model construction of large area similar buildings, and the modeling efficiency is greatly improved.%从三维建模所需数据的获取到地形、地物模型的构建等方面进行探讨，研究了系统三维GIS场景的建立方法，并且，选取XX地区作为研究区域，包括数据的获取及处理、地物与地形的匹配，然后基于规则对三维场景进行建筑物、道路、操场、树木等模型构建并导出到Geodatabase数据库中。基于规则的三维场景建模方法适用于大面积相似建筑物的模型构建，并且大大地提高了其建模效率。
