1. A method comprising:
acquiring a plurality of jointly collected data, wherein the plurality of jointly collected data comprises seismic wave data that comprises a seismic wave component and electric field data that comprises an electric field component;
performing a jointly imaging processing onto the plurality of jointly collected data by obtaining a dispersion spectrum of the seismic wave component and a dispersion spectrum of the electric field component according to the seismic wave component and the electric field component, respectively, and superposing the dispersion spectrum of the seismic wave component and the dispersion spectrum of the electric field component to obtain a superposed dispersion spectrum;
performing an extraction processing onto the superposed dispersion spectrum to obtain a dispersion curve; and
performing an inversion processing onto the dispersion curve to obtain a stratum structure profile.
