Summary: | The invention discloses an imaging domain least square migration method and device, electronic equipment and a medium. The method comprises the following steps: acquiring a global space-variant scattering function, and performing interpolation reconstruction on the global space-variant scattering function to generate a plurality of scattering function data volumes; according to the depth domain imaging body, calculating the spatial deconvolution of the plurality of scattering function data bodies through an MPI parallel strategy, and obtaining a corresponding least square offset image; and carrying out reduction on the least square offset images corresponding to the plurality of scattering function data volumes to obtain a final imaging result. According to the method, the point spread function is encrypted through an interpolation reconstruction strategy, meanwhile, deconvolution after reconstruction is performed, discontinuous noise is suppressed through multiple times of superposition, and higher imaging p |
