Density inversion method, apparatus and electronic device

A density inversion apparatus comprising:

• an anomaly acquisition module configured to acquire local gravity anomalies of a target body to be measured at a plurality of measurement points within a target measurement area, wherein an area where the target body to be measured is located is in the target measurement area, and the target body to be measured is a geological body at a specified depth;
• an information acquisition module configured to acquire information of distance between a center position of the area where the target body to be measured is located and a specified boundary, wherein the specified boundary is a boundary of the target measurement area;
• a depth determination module configured to determine a target inversion depth to be used in density inversion for the target body to be measured based on the information of distance and the specified depth;
• and
• a density determination module configured to substitute the local gravity anomaly of the target body to be measured 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 to be measured in a transverse cross-section, wherein the layer density inversion formula is a transform formula of a density inversion formula in the case of a constant density in a longitudinal cross-section.
