摘要：

为实现矿井三维场景的快速构建和可视化表征,针对当前矿井三维模型开发难度大、可操作性差等缺陷,提出一种基于开源程序的矿山三维井巷模型快速生成方法。首先,以采集的矿山井巷属性信息为基础,借助MySQL数据库实现数据的自动导入和规范化存储;其次,通过分析联通巷道的几何特征,建立平直、倾斜与竖直巷道等不同类型巷道的解构思路,提出相应的参数化表达方法;然后,利用Python和Blender开发平台快速生成矿山三维井巷模型;最后,为验证该方法的有效性,开展T型、Y型等联通巷道及典型开拓模型的快速构建。结果表明:所提出参数化建模方法将三维建模简化为“参数+算法”,实现了三维井巷模型的快速构建,较好地处理了联通巷道建模失真等难题;所构建的系统平台,利用输入的关键数据即可实现矿井三维场景的快速构建。

Abstract:

In order to achieve rapid construction and visual characterization of 3D mine scenes, a fast generation method of 3D mine tunnel model based on opensource program was proposed considering the drawbacks of current method, such as great difficulty and poor operability. Firstly, based on collected mine shaft and lane attribute information, automatic import and standardized storage of data were realized with help of MySQL database. Then, geometric characteristics of connecting roadway were explored, different types of roadway, including conventional straight, inclined and vertical roadway, were deconstructed, and parameterized expression of 3D model was proposed. Then, Python and blender development platforms were used to generate 3D roadway system model. Finally, T type and Y type connecting roadways and typical development models were reconstructed rapidly to verify effectiveness of this method. The results show that the proposed parametric modeling method simplifies 3D modeling into "parameter + algorithm", thus achieving rapid construction of 3D tunnel model, and it also solves problems like distortion. Moreover, the developed system platform can realize rapid construction of mine virtual scenes based on key data.
