Lymph node metastasis detection method and device for pathological image, equipment and storage medium

The invention belongs to the technical field of image processing, and discloses a lymph node metastasis detection method and device for a pathological image, equipment and a storage medium, and the method comprises the steps: carrying out the image segmentation of the pathological image through a pre-trained segmentation model, obtaining a prediction image, determining a metastatic focus region with the maximum area in the prediction image, and obtaining a prediction result; taking the maximum side length of the minimum enclosing rectangle of the transfer focus area as the longest diameter, and determining a transfer detection result of the pathological image based on the longest diameter; wherein the segmentation model comprises a coding layer and a decoding layer which are connected in sequence, the coding layer comprises a feature extraction layer and a spatial pyramid pooling layer which are connected in sequence, the feature extraction layer comprises a cavity convolution layer and a depth separable conv
