| description | The invention discloses a three-dimensional stratum modeling method based on a geological map-cut profile. The method comprises the steps: S1, editing the map-cut profile, and completing the setting of basic parameters needed by modeling; s2, discrete sampling is conducted on the stratum boundary and the inner and outer areas, and discrete distribution of stratum attributes in space is obtained; s3, performing interpolation calculation on the stratum three-dimensional space discrete points to generate a three-dimensional space stratum attribute data field; s4, contour surface extraction is carried out from the three-dimensional space stratum attribute data field, and a three-dimensional contour surface of the stratum is obtained; s5, repeating the steps S2 to S4 to obtain three-dimensionalcontour surfaces of all stratums; s6, spatial splicing is conducted on the surfaces of the three-dimensional contours of all the stratums, and three-dimensional stratum modeling is completed. According to the method, the pro |
