摘要
当前巷道三维建模是数字矿山的重要组成部分,通过现有技术手段建立的巷道模型虽然满足可视化需求,但由于精度不高,无法满足分析算法和可视化渐变效果的要求。提出了通过生成三角面片的方法,动态创建矿山巷道三维模型。通过阐述巷道断面、巷道壁、巷道底面和巷道交点过渡模型的三角面片建模机制,结合布尔并集运算融合模型,建立满足指定精度要求的矿山巷道三角面片三维模型。
At present,3D modeling of roadway plays an important role in digital mining.Although the roadway model established by the existing technical methods meets the needs of visualization,it can’t meet the requirements of the analysis algorithm because of the low accuracy.In this paper,the dynamic three-dimensional model of mine roadway was proposed by the method of generating triangular faceplate.The three-dimensional model of the three-angled face of mine roadway was established by expounding the triangular facet modeling mechanism of the transition model of roadway fault,roadway wall,roadway bottom surface,and roadway intersection point,and combining with the Boolean parallel operation fusion model.
