| description | The invention discloses a geophysics inversion method based on a generic function reconstruction under a modified total variation model constraint. The method comprises the following steps: (1) constructing an inversion objective function aiming at the problem of regularized inversion of the modified total variation model constraint; (2) performing a generic function reconstruction on stable function terms of the modified total variation; (3) iteratively solving a calculation formula of a new model on the model itself according to an objective function minimization equation; and (4) setting inversion parameters, repeating the iteration to obtain a desired model result, and the result is used for inferring geological structures or positioning geological anomaly bodies. According to the geophysics inversion method based on the generic function reconstruction under the modified total variation model constraint, a generic function reconstruction method is innovatively provided, and the constraint property of the |
