| description | The invention relates to an exposure abnormity early warning method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining a plurality of prediction images of a to-be-scanned object generated based on a preset exposure parameter; according to the gray value, the overexposure gray threshold and the underexposure gray threshold of each pixel point in each prediction image, determining the number of abnormal exposure images in the prediction image; and if the number of the abnormal exposure images is greater than a first number threshold, generating prompt information for adjusting exposure parameters. The doctor is prompted to adjust the exposure parameters in time through the prompt information, so that overexposure or underexposure in the actual scanning process is avoided, and image artifacts generated by overexposure or underexposure are further avoided.
