Amplitude fidelity seismic imaging method and device, electronic equipment and medium

The invention discloses an amplitude fidelity seismic imaging method and device, electronic equipment and a medium. The method comprises the following steps: performing angle decomposition on a seismic source wave field and a detection point wave field in reverse time migration to obtain a non-amplitude-preserved angle domain imaging gather without illumination correction; calculating an angle domain illumination compensation factor of the observation system; and according to the angle domain illumination correction factor and the non-amplitude-preserving angle domain imaging gather without illumination correction, carrying out imaging amplitude correction to obtain an amplitude-fidelity seismic imaging gather. According to the method, reverse time migration and one-way wave illumination analysis are combined, the problem of imaging amplitude distortion caused by uneven illumination of an imaging propagation operator and an observation system is accurately corrected, the angle domain amplitude fidelity gather
