A tire surface bar code correction method and device based on density segmentation
By using a density-based segmentation method, barcode feature data sets on the tire surface are obtained, segmentation boundaries are determined, and correction processing is performed. This solves the problem of insufficient barcode distortion correction accuracy in existing technologies and achieves a significant improvement in barcode recognition rate.

Abstract
The present application relates to the technical field of image processing, in particular to a tire surface bar code correction method and device based on density segmentation. The method comprises: obtaining an initial bar code image; obtaining a bar code feature data set based on the initial bar code image, determining a bar code segmentation boundary position based on the bar code feature data set, and segmenting the initial bar code image based on the bar code segmentation boundary position to obtain a plurality of bar code region images; and performing correction processing based on the bar code region images to obtain a corrected bar code image. In this way, the uniformity of the bar code can be effectively restored, thereby significantly improving the bar code recognition rate.
