Zusammenfassung:The invention discloses a diffraction recognition imaging method and device, electronic equipment and a medium. The method comprises the following steps: obtaining a common imaging point dip angle gather according to a seismic source signal and common shot point data; overlapping the common imaging point dip angle gathers to obtain an offset imaging overlapped section, and recording coordinate positions of discontinuous scattering points and reflection points; determining diffraction energy vector labels and reflection energy vector labels, and establishing a label sample library; identifying an amplitude vector of each imaging point in the common imaging point dip angle gather, and determining a label of each imaging point through a KNN algorithm according to a label sample library; and superposing the inclination angle gathers of the imaging points of which the labels are diffraction labels to obtain a diffraction wave imaging result. According to the method, rapid and efficient imaging of diffraction energ
