摘　　要：针对目前虚拟校园系统以2.5维为主,模型纹理失真,Web三维显示需要插件等问题,设计了一种采用倾斜摄影测量建立三维模型,使用四叉树索引数据结构,基于Three.js搭建的虚拟校园系统。该系统较好的解决了模型纹理失真、建模周期长、效率低等问题,实现了无需插件支持的跨平台展示,具有良好的真三维Web系统交互效果,同时能够根据不同需求开发组件式功能模块。In view of the problem that the 2.5 dimensions virtual campus system, model texture distortion and the need for plug-ins in Web 3D display, a virtual campus system is designed based on Three. js, which adopts oblique photogrammetry to build a 3d model, USES quadtree index data structure. The system solves the problems of model texture distortion, long modeling cycle and low efficiency, and realizes the cross platform display without the support of the plug-in. It has good interactive effect on true 3D Web system, and can develop component functional modules according to different requirements.
