倾斜摄影三维模型网络可视化技术研究

Research on network visualization technology of 3D models from oblique photography

随着倾斜航空摄影技术在三维数字城市建设中的应用不断普及,构建三维模型的自动化程度及生产效率得到了显著提高。在此背景下,如何对大量倾斜摄影三维模型进行高效可视化成为一项新的研究课题。本文研究了倾斜摄影三维模型的组织管理、服务发布及可视化的技术路线,构建了基于WebGL的三维模型数据管理原型系统,实现了大量倾斜摄影三维模型数据的格式转换、存储管理、高效调度及实时可视化。利用原型系统对实验数据进行可视化实验的结果表明,该系统的可视化效果良好,能够满足快速可视化需求。

With the increasing popular of oblique aerial photography technology in 3D digital city con‐struction,the automation and production efficiency of 3D model construction have been significantly improved,and how to efficiently visualize a large number of 3D models from oblique photography have become a new topic.This paper studies the technical route of data organization,service release and visualization of 3D models from oblique photography,builds a 3D model management prototype system based on WebGL,and realizes the data format conversion,storage management,efficient sched‐uling and real-time visualization of a large number of 3D models.It conducts a visualization experiment to test data through the prototype system.The results showed that the visualization of the system is good,and the system can meet the requirements of rapid visualization.
