基于球面全景影像的矿山场景三维重建
|
摘要
三维建模是智慧矿山建设面临的核心内容之一。文中针对传统方法建模复杂、效率低、不够直观等问题,将虚拟现实领域的三维全景技术融入智慧矿山,系统研究了球面全景影像生成方法,给出基于球面全景影像的虚拟场景交互与路径规划方法,最后设计了三维全景智慧矿山原型系统。实验结果表明,基于全景序列影像的矿山场景增强现实能够有效弥补传统方法不足,可用于展示矿山真实场景,为设计生产、安全管理、勘探数据验证以及教育培训提供一个真实的可视化平台,方便管理人员做出正确决策。
Three-dimensional spatial expression was one of the important issue in smart mine construction. In this paper,three-dimensional panorama technology was introduced from virtual reality into smart mine to deal with the problem in traditional method in difficult expression,complicated modeling and low intuition. Then,the algorithms of panoramic image generation was studied,and the method of virtual scene interaction and roaming path planning was proposed. Finally,a prototype smart mine system was developed based on RIA technology. The results indicated that mine scene augmented reality based on panoramic sequence image could effectively make up for the shortage of traditional methods. It could be used to display real scenes of mines,providing a real visualization platform for design production,safety management,exploration data verification and education training,which was convenient for managers to make correct decisions.
