| 摘 要： | 针对目前所提出的三维巷道模型算法较为复杂,算法针对不同巷道通用性不强,甚至有些还需要虚拟现实硬件设备配合等不足,本文通过对矿山巷道的特点及基本形状进行分析、研究,提出了一种利用巷道中轴线的三维坐标和巷道掌头的三维坐标,通过构造几何图形和近似坐标轴,再沿中轴线加载截面的巷道三维模型的算法思想。该模型为巷道的虚拟漫游提供了一种直接简便的算法。

| Abstract: | The current proposed algorithm of three-dimensional tunnel model is more complicated.The algorithm is not used for all different laneway,and even needs some coordination with virtual reality hardware devices.Taking into account these shortcomings,through analysis and research on the characteristics and basic shapes of mine laneway,this paper presented the algorithm idea of three-dimensional model of tunnel by means of the three-dimensional coordinate of the tunnel axis and the tunnel palm head to construct geometry and approximate axis,and then load the cross-section along the axis.The model could provide a simple and direct algorithm for the virtual roaming of tunnel. |
