网络三维虚拟校园仿真平台构建

Abstract

基于三维可视化、计算机网络等技术，实现校园室内外一体化三维虚拟仿真平台构建与发布。通过师院二维校园平面图，结合遥感影像数据，依据真实校园场景布局进行三维场景建模。基于CityEngine的CGA (Computer Generated Architecture)规则语言进行的校园三维场景构建，实现建筑物模型的快速生成和纹理自动映射，以及室内场景与行人、车俩、动态水和标志性建筑物等特殊模型的快速构建。同时，将摄像头等多源时空数据与校园管理系统接入三维校园平台，实现各教学楼属性信息和安防多媒体信息的展现与查询。此外，通过自动漫游等功能可对校园进行多方位展示。 Based on the technologies such as 3D visualization, computer network and so on, the establish-ment and publishment of campus indoor and outdoor integration 3D virtual simulation platform have been achieved. Through the 2D campus plan of the Guangxi Teachers Education University, combined with remote sensing image data, 3D scene is modeled according to the real campus scene layout. Campus 3D scene construction, based on CGA (Computer Generated Architecture) rule language of City Engine, has achieved the rapid generation of building models and automatic texture mapping, as well as the rapid construction of indoor scenes and pedestrians, cars, dynamic water, landmark buildings and other special models. At the same time, the multi-source spatio-temporal data such as camera and campus management system are connected into 3D campus platform so that the display and inquiry of the attribute information of teaching buildings and security multimedia information can be achieved. In addition, the campus can be displayed in different directions through functions such as automatic roaming.
