Problems solved by technology

Changes in the position of the subject at different shooting times, changes in the position of the shooting equipment at different shooting times, or other changing factors may cause abnormal grayscale differences between different images, such as the same part of the shooting object in different images There is a large difference in grayscale, or there is a large difference in grayscale contrast between two adjacent parts of the subject in different images
Furthermore, the spliced ​​images have abnormal grayscale differences on both sides of the splicing place, and the image stitching quality

Abstract

The invention discloses an image processing method device, apparatus and a storage medium. The image processing method comprises the following steps: obtaining a gray distribution of an overlapping area of a first image and a second image in the first image to obtain a first gray distribution; Acquiring a gray level distribution of the overlapping region in the second image to obtain a second graylevel distribution; Determining a gray level transformation function with reference to the first gray level distribution and the second gray level distribution; Converting gray levels of the first image and the second image to a matching state according to the gray level conversion function. according to embodiment of that present application, the gray level difference between the two images canbe adjust to a predetermined normal range. Furthermore, if two images transformed to the matching state are stitched, the abnormal gray difference between the two sides of the stitched image can be avoided as much as possible.

Description

Technical field [0001] This application relates to the field of image processing technology, in particular to image processing methods and devices, equipment and storage media. Background technique [0002] In imaging scenes such as medical imaging, drone aerial photography, and remote sensing imaging, it is necessary to stitch two or more images obtained by shooting the same object. The stitched images are usually taken at different times. Changes in the position of the subject at different shooting times, changes in the location of the shooting equipment at different shooting times, or other changing factors may cause abnormal grayscale differences between different images, such as the same part of the subject in different images There is a big difference in grayscale, or there is a big difference in grayscale contrast between two adjacent parts of the subject in different images. Furthermore, the spliced ​​images have abnormal grayscale differences on both sides of the splici...
