摘要
针对当前城市三维建筑模型数据格式复杂、网络应用效率低的问题,本文将流媒体传输技术引入到3DWebGIS应用中,提出了一种基于glTF等格式和3D Tiles数据组织方式的异构三维建筑模型流媒体转换和组织方法,设计了人工建筑模型、倾斜摄影、激光点云三维模型的流媒体转换流程。以浙江新昌相关数据为例,完成了这些成果流媒体转换及网络发布,使用Cesium.js框架实现了转换成果的无插件网络浏览,提升了三维建筑模型的网络传输和使用效率。
In view of the complicated data format and low network application efficiency of urban 3D building model,the streaming media transmission technology is introduced into 3DWebGIS application.This paper presents a heterogeneous 3D building model glTF format and 3D Tiles data organization based on streaming media conversion and organization methods,design of artificial building model,photography,laser point cloud three-dimensional model of tilt of the streaming media conversion process.In Zhejiang Xinchang data as an example,to complete these results of streaming media conversion and network release,use Cesium.js framework to realize web browsing without plug-in conversion results,enhance the 3D building model and network transmission efficiency.
