摘要： 结合传统巷道收敛仪与三维激光探测系统的优势，提出了一种巷道表面收敛变形的三维可视化方法，该方法利用激光扫描获取巷道点云数据，建立巷道三角形壳体模型.采用反距离加权插值算法，计算巷道表面的收敛量.利用收敛量与颜色索引对应的抛物线非线性增强算法，突出了关注范围内大的收敛变形.基于VS2010与HOOPS进行了系统的开发，实现了巷道表面监测收敛量三维云图的动态可视化显示.并在铁蛋山矿进行了实例应用，直观地展示了监测区域巷道收敛变形的危险区域与变形过程，系统满足工程人员对监测数据直观表达和可视化分析的需求.

Abstract: Combined with the advantages of traditional laneway convergence measure instrument and 3D laser scanning， a method for obtaining and presenting laneway convergence via 3D visualization was proposed. This method utilizes laser scanning point cloud data from laneway to reconstruct shell model by triangulation. The inverse distance weighted interpolation algorithm is then employed to compute the convergence of the laneway periphery. A parabolic nonlinear enhancement algorithm is further developed based on the one-to-one correspondence between the convergence and the color index， in order to highlight the more obvious convergence within the study area. The whole system was developed using VS2010 and HOOPS， which realizes the dynamic visualization of the 3D convergence contour obtained from surface monitoring. The application of the developed system in the Tiedanshan mine clearly and vividly showed the dangerous area and deformation process of laneway which satisfied the engineers′ requirement for direct presentation and real-time visualization of monitoring data.

Key words: surface convergence, deformation monitoring, data analysis, 3D laser scanning, visualization
