摘　　要：三维建模技术是整个虚拟现实系统建立的基础,是虚拟现实所有应用中一个关键的步骤和技术,基于VirtuoZo与IMAGIS在城市三维建模中的应用,以黑龙江工程学院的校园影像为例,对建筑物三维坐标采集的规则进行研究,经过数据准备,提取校园建筑物的XYZ数据、DEM、DOM数据,通过实地拍摄建筑物的立面影像,构建空间位置精确的三维模型;通过低效率的手工操作粘贴建筑物的真实纹理,实现AVI视频文件,最终实现建筑物的三维漫游。3D modeling is the foundation of virtual reality system ,which is one of the key procedures ,and core technology of virtual reality .Combining both VirtuoZo with IMAGS together ,this paper introduces a 3D coordinates data collecting method of buildings and discusses the relative rules ,taking the campus image information of Heilongjing Institute of Technology as an example .Accurate 3D modeling can be achieved by collecting the 3D coordinates , DEM , DOM , and taking actual facade image of buildings . After inefficient manual pasting for the texture of buildings ,3D modeling can be visualized in the form AVI videos ,and finally the virtual reality system of buildings can be generated .
