| This thesis has given a arithmetic of Delaunay Triangle network (?)ith constrained condition,The method was fit for the Open-pit data composed of points and poly-lines.To complete the establishment of three-dimensional model of open-pit mine,CDT model was high-precision and approached actual open-pit.This thesis takes the Weijiabao Surface Mine as an example,to empolder 3D visualization system including data processing of current map,establishing Delaunay triangle network with constrained condition,Border processing and the 3D-model of stope and so on.This system is based on AutoCAD to face the program language-- ObjectARX,in order to give a secondary development.The system has been a good application on the Weijiabao Surface Mine which indicated that the system had the characteristic of practicality,easy operation and stabilization。... |
