文化特色街区网络多导系统三维数据库建设研究

Three-dimensional database construction in cultural characteristic block network guide system

为了解决文件方式管理三维模型数据存在缺陷的问题,以面向对象的思想自上而下地对虚拟场景进行剖分,构建元模型库。基于关系数据库,实现三维模型的存储、查询、共享等管理机制。通过对数据库中的三维模型进行有效的调度和组合,再对处理后的影像和地形进行叠加、匹配,即可生成虚拟场景。研究结果能够为相似虚拟场景提供建模及导览服务。

In order to solve the defect of3D model file in data-managing,we built a meta model library from top to bottom with the object-oriented thought to subdivision of virtual scene,based on the relational database,to realize the management mechanism of the3D model,such as storage,query,and sharing.Through effective scheduling and combination,image processing,terrain superposition and matching,the virtual scene was generated.The results can provide similar virtual scene modeling and navigation services.
