[Abstract]:In order to solve the problem of 3D modeling of roadway caused by the changing of roadway section in mine engineering, a 3D modeling algorithm for roadway segment of characteristic section based on wire-frame model is proposed. Firstly, the process of data acquisition and pretreatment is described, and the method of data acquisition and processing for irregular roadway section is put forward, and the topological structure of the elements contained in the roadway section is analyzed. At the same time, according to the diversity of roadway section in the mine, The model base of roadway characteristic section is established, the coordinate refinement analysis of regular roadway section and irregular roadway section is realized, the discretization algorithm of corresponding roadway characteristic section is designed, and the characteristic section is discretized into section point. Based on the 3D coordinate of the center point of the characteristic section, the section point is transformed into the space coordinate and loaded into the control point of the corresponding center line of the roadway. At the same time, the smoothing algorithm of the section of the roadway at the corner of the roadway is proposed. In order to improve the efficiency of 3D modeling of different roadway segments, the three-dimensional modeling of roadway centerline is processed and the three-dimensional modeling of roadway segment is based on the idea of wire-frame model modeling and triangulation is used to form triangulation network to complete the modeling of roadway segment.
