地下矿山斜坡道三维模型参数化构建方法研究

针对地下矿山斜坡道建模技术不完善且在矿山的应用程度低的问题，基于参数化思想开展了地下矿山斜坡道三维建模方法研究。首先，根据斜坡道断面参数，构建斜坡道断面的二维轮廓线；其次，根据斜坡道路径参数，经系列坐标转换得到斜坡道断面的三维轮廓线；再次，采用连续断面的侧面构建算法快速建立斜坡道三维模型；最后，将斜坡道的模型参数存贮于相应模型的数据结构中，以便于计算其工程数据和检索、查询、动态修正模型参数。借助该方法和HOOPS组件，运用VC++工具，开发了一个地下矿山斜坡道参数化建模系统。基于该系统并根据某矿山地下斜坡道的路径平面图、斜坡道坡度和断面参数信息，成功构建了斜坡道的三维参数化模型，并能根据矿山施工进展动态修正模型。

Research on a Method of Parameterized 3 D Modeling of Mine Ramp

Aiming at the actuality of the imperfection and low application rate of the model-building technique of mine ramp，we research the method of 3D-modeling based on parametric idea.Firstly，we build a parameterized 2D model contour of the ramp according to its cross section parameters.Secondly，building a 3D model contour of the ramp sections via coordinate transformations on the basis of the parameters of its path.And then，a 3D model of the ramp is quickly created according to the algorithm which utilize the side face of consecutive cross section.Finally，the model parameters are saved in its corresponding database so that we may finger up the engineering data and query or modify the model dynamically.With the help of the method mentioned above，together with HOOPS components and VC++ tools，we develop a parametric modeling system of the mine ramp.Based on this system and the planar graph，gradients and other parameters of a mine ramp，we built a parameterized 3D model for the ramp and modified it as the condition changed during the construction process of the mine ramp.
