The invention relates to a 3D-SOBEL-based local anisotropic search ellipsoid generation method. The 3D-SOBEL-based local anisotropic search ellipsoid generation method comprises the steps of S1, acquiring coordinate nodes and topological information of an ore body model; s2, constructing an ore body mesh model based on the coordinate nodes and the topological information, performing indication processing on the ore body mesh model, calculating the gradient of each unit position in the ore body mesh model, and obtaining boundary information of the ore body mesh model; and S3, according to the boundary information, obtaining an ellipsoid form at the boundary of the ore body mesh model, calculating ellipsoid form parameters at the boundary of the ore body mesh model, and generating a search ellipsoid model in the ore body. According to the method, the internal ellipsoid direction is determined based on the ellipsoid direction at the boundary, calculation is relatively simple, and variation functions or other com
