Title:
DENSITY INVERSION METHOD AND APPARATUS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/280123
Kind Code:
A1
Abstract:
Embodiments of the present application provide a density inversion method and apparatus, and an electronic device. The method comprises: obtaining local gravity anomalies of a target object under measurement at a plurality of measurement points in a target measurement area (S101); acquiring distance information between a center position of an area where the target body is located and a specified boundary, wherein the specified boundary is the boundary of the target measurement area (S102); on the basis of the distance information and a specified depth, determining a target inversion depth utilized when performing density inversion on the target object (S103); and substituting the local gravity anomaly of the target body at each measurement point and the target inversion depth into a preset layer density inversion formula to obtain a density distribution of the target body on a transverse cross section, wherein the layer density inversion formula is: a deformation formula of the density inversion formula under the condition that the longitudinal cross section density is unchanged (S104). On the basis of the present solution, the accuracy of the density distribution obtained by inversion can be improved.
