摘　　要：岩矿标本具有唯一性和不可再生性,传统的馆藏展示不方便专业人员学术交流,同时也限制了地学科普工作的高效开展。以太原西山煤田为例,针对采集到的350块代表性岩矿标本,探索小尺度岩矿标本精细化三维建模及虚拟仿真平台建设。首先运用多视图图像三维重建技术,设计匹配的三维环物摄影装置,采集图像数据;而后针对原始图像质量和建模软件两个因素,优化建模精度;最后,结合WebGL技术搭建起西山煤田岩矿标本虚拟仿真平台,并通过数据格式转换实现三维模型浏览器加载速度优化。实践表明,岩矿标本精细化三维建模及其虚拟仿真平台搭建,有效地提高了地质标本共享程度和科普程度,提升了煤矿地质技术人员的专业素养。Rock and mineral specimens are unique and non-renewable.The traditional collection display is not convenient for professional academic exchanges,which limits the efficient development of the popularization of geosciences.350 representative rock and mineral specimens of Xishan Coalfield in Taiyuan City are collected to explore the fine 3D modeling of small-scale rock and mineral specimens and to construct a virtual simulation platform.First,the multi-view image 3D reconstruction technology to design a matching three-dimensional ring object photography device is used to collect image data.Then modeling accuracy is optimized from two aspects of original image quality and modeling software.Finally,by WebGL technology,a virtual simulation platform of rock and mine specimens of Xishan Coalfield is built,and the optimization of the loading speed of the 3D model browser through data format conversion is achieved.The practice shows that the fine three-dimensional modeling of rock and mine specimens and the construction of its virtual simulation platform have effectively improved the sharing and popularization of geological specimens,and improved the professionalism of coal mine geological technicians.
