基于实测边界线的地下巷道三维建模方法
3D modeling method for laneway entities based on measured boundary lines
摘要
Abstract
A hierarchical modeling method for measured laneway entities based on boundary lines and cross section was proposed. The basic idea of the method was described as follows. Spatial organization of regions (containing holes) generated by boundary lines was represented using tree structure. Surface described by triangles was generated by regions using constrained triangulation method. The sides expressed the export location in triangulations and the bottom of section were picked up. Cross section contours were generated according to section parameter. Symmetrical points were generated by sections constituted laneway entity feature points. The cross-section data were obtained, and a series of hierarchical contours were built, which composed the hierarchical contours of the laneway entity. Finally, triangular girds of laneway were generated by 3D objects reconstruction of adjacent contours and triangulation of both roof contour and bottom contours. The results show that the topology of region and section parameter can be used to reduce calculation burden and simplify the implementation.关键词
