Bedrock geologic body three-dimensional model construction method and device based on map-cut geologic parallel sections

The invention discloses a bedrock geologic body three-dimensional model construction method and device based on graph-cut geologic parallel sections. The method specifically comprises the steps: (1) loading two-dimensional graph-cut section vector data and a base point data table; (2) constructing a stratum pair set COU based on two adjacent two-dimensional graph cut profile elements; (3) readinga stratum pair from the COU, and constructing a boundary line set AL and a boundary line set BL; (4) converting the boundary line set AL and the boundary line set BL from two dimensions to three dimensions based on the base point data table; and (5) constructing a three-dimensional continuous geologic body and a three-dimensional sharp geologic body based on a Morphing trilateral method. Comparedwith the prior art, the method for quickly constructing the three-dimensional model of the bedrock geologic body has the advantages that the automation degree is high, and the modeling quality of thethree-dimensional model of
