The application discloses a kind of underground mine three-dimensional
entity model establishing method, device and medium.The method includes: S1, AutoCAD
software imports two-dimensional drawing, and drawing is divided into different
layers according to mining middle section;S2,
clean up invalid
graphics;S3, conversion line type,
clean up layer;S4, process middle section broken line,
closed loop;S5, target middle section DXF file is imported into GEOVIA Surpac
software, generates str file;S6, adjust point elevation and
line segment slope, generate floor str file;S7, adjust floor str file, generate top surface str file;S8, create floor and roof DTM model;S9, close bottom surface and top surface DTM model, form target middle section three-dimensional
entity model;S10, combination forms overall three-dimensional
entity model.The application makes full use of AutoCAD
software to quickly process two-dimensional drawing on the advantages of messy point, redundant line and
control layer, combined with GEOVIA Surpac software three-dimensional space modeling technology, improve the efficiency of two-dimensional
plane figure to establish complex three-dimensional entity model.
