The invention discloses a
solid three-dimensional model construction method for a monoclinic rock stratum structure
landform, and the method comprises the steps: (1) calculating the attitude of a monoclinic rock stratum according to a monoclinic rock stratum geological map and DEM data, and obtaining a geological
boundary line set and an attitude set; (2) according to the rock stratum attitude set, dividing the geological
boundary line into a plurality of rock stratum surface
boundary line segments with consistent attitudes; (3) according to the boundary
line segment of the rock stratum surface, adopting a occurrence deduction method to obtain an attitude deduction point through deduction, and obtaining a rock stratum surface comprising the rock stratum surface and the rock stratum side surface; (4) according to the rock stratum side faces, generating fault layer faces through
sequential combination; (5) according to the geological boundary line set, based on
Morphing, carrying out interpolation to generate interpolation points of all rock
layers in the rock layer set; and (6) generating the
TIN of the rock stratum surface, the rock stratum side surface and the fault layer surfaceby adopting a point-by-point
insertion method according to the interpolation points of the rock stratum surface, the fault layer surface and the rock stratum surface, and performing sewing to obtain asolid three-dimensional model. The method is higher in accuracy.
