An impedance inversion method via the anisotropic total variation regularization and the initial model constraint is presented.In order to make use of the spatiotemporal information of the seismic data and improve the lateral continuity of the inversion results,multi-trace inversion is used in this method.The experimental results show that even in the case of strong noise interference,this method can achieve good inversion results with small errors.

Key words: impedance inversion, L1 norm, anisotropic total variation, regularization, initial model, constraint
