Image processing model training method and device, electronic equipment and storage medium

The invention provides an image processing model training method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a plurality of multi-modal images used as training samples, wherein the types of the multi-modal images comprise full-modal images and missing-modal images; based on each multi-modal image, calling an initialized image processing model to execute a first training task for reconstructing a full-modal image, and in the process of executing the first training task, outputting a first full-modal reconstructed image by the image processing model; performing image completion processing on each first all-modal reconstruction image based on the all-modal image to obtain an all-modal template image; determining the consistency loss between the multi-modal image pair and the full-modal template image; and based on each multi-modal image, calling the trained image processing model to carry out a second training task of segmenting each multi-modal imag
