Abstract:

Abstract: In order to solve the problems of surface roughness and inaccuracy of orebody caused by the incompletion of modeling information or few data,a high quality 3D modeling method based on space contours was proposed.The specific modeling steps are as follows:First,according to the stratum properties and elevation to check consistency of space contours intersection and topology preprocessing.Then,the topology relationship between node and path network was built and the space gird of the spatial contours was extracted with the inner path first search algorithms.At last,the separate model for space grid was constructed by adopting the method of generation the transition contours,a complete surface model of the orebody was formed by seamless splicing the reconstructed space grid.The research results show that this method can simplify the operation of users,improve the efficiency of modeling,and surface model generated more realistic.

Key words: 3D surface reconstruction, space contours, topology relationship of node-path,
