CMS-VRML耦合的网络环境下采空区三维可视化方法

针对精确获取的采空区三维数据难以在Internet上可视化表达的问题,提出了在网络环境下,基于CMS-VRML耦合的采空区三维可视化方法。运用CMS精确获取采空区的三维空间数据,使用CMS-PosProcess软件将TXT格式的原始数据转换成DXF格式文件,利用VRML软件对DXF格式的三维模型进行编译,生成WRL格式的采空区三维模型,最终,用户可以通过IE等浏览器在网络上直接浏览空区模型。实践表明,CMS-VRML耦合生成的三维模型在网络环境下数据冗余小,可视化效果好,交互性强,从而为矿山空区安全监管提供了一种新的技术手段。

3D Visualization Method for Mined-out Area Based on Coupled CMS-VRML in Network Environment

Aiming at the problem that the visual expression of the precise three-dimensiona l data of mined-out area in Internet is difficult,a 3D visualization method for mined-out area based on coupling of CMS (Cavity Monitoring System,CMS) and VRML (Virtual Reality Modeling Language) in network environment was proposed.CMS is u sed to obtain accurate the 3D spatial data of mined-out area,then the raw data s tored as TXT files are transformed into files with DXF format by CMS-PosProcess software,and the three-dimensional model with DXF format are compiled to files w ith generate WRL format,so the three-dimensional model of mined-out area can be browsed in network directly by IE.The practical results show that the data redun dancy of three-dimensional model generated by coupled CMS-VRML in network enviro nment is small,the effect of visualization is perfect and the interactive perfor mance is good,thereby it provides a new technological means for the safety super vision of mined-out areas in mines.
