Abstract

The invention provides a date detection processing method and device in a label image. The method comprises the steps: carrying out the graying of the label image, carrying out the binarization of thegrayed label image, and obtaining a binary image; performing frame extraction on the binary image to obtain a frame of the binary image, and removing the frame of the binary image to obtain a targetimage with the frame removed; traversing all pixel points of the target image, carrying out region communication on the target image to obtain a plurality of communication regions of the target image,and carrying out pixel inversion processing on the target image after region communication; the contours of the plurality of connected regions after pixel inversion are acquired, the bounding boxes of the plurality of connected regions are generated according to the contours, and the inspection result of the date is determined according to the bounding boxes, so that the problem that the date cannot be accurately identified when the date and the border in the label are close to each other or close to each other in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a date detection and processing method and device in a label image. Background technique [0002] In the catering field, almost all edible items must carry a production date and an expiration date. Therefore, many merchants directly paste the label with the date on the packaging of the item, so as to reflect the production date and expiration date of the item. In order to uniformly manage the date information of these items, the date information on the label can be obtained through OCR technology, and then the identified information can be entered into the background management system. [0003] The date information obtained by OCR technology on the label can be roughly divided into two parts: detection and identification. Firstly, the position of the date in the label is detected; then the date part is extracted, and the part is identified to obtain the date information. [000...
