Research on Rapid Modeling Method of Mine Complex Roadway Based on Pattern Recognition:Taking Section of the Cotton Keng Uranium Deposit
When dealing with the construction of complex roadway 3D model,the traditional midline method and waist line method are faced with many problems,such as heavy workload,many times of adjustment and difficult closure of roadway entity.Based on polygon pattern recognition theory,a rapid modeling method for complex roadway was proposed.Firstly,the measured roadway's lumbar line was sorted to make the line segment closed without repeating line segment.Then,the space surrounded by roadway was Delaunay triangulated on the plane to generate a series of triangles,and the roadway center line was generated accordingly.Next,a series of auxiliary lines are generated according to the position relationship between the control point and the center point of the roadway top surface.Finally,DTM(digital terrain model)planes are generated according to these lines in three-dimensional space to form the roadway entity.By using object-oriented programming and programming method,the feasibility of the fast modeling method of complex roadway is verified by drawing the roadway model of-100 m middle section of the cotton Keng uranium deposit.The results show that it is convenient and fast to adopt this aspect of modeling,and can solve the problem of long modeling cycle of complex roadway,which is of great significance to quickly establish the digital model of the whole mine.
