AI Technical Summary

Technical Problem

In existing technologies, micro-coded images are difficult for users to identify due to their irregular coding characteristics, resulting in low recognition. This is especially true in scenarios with high concealment and anti-copying capabilities, where ordinary users have even less knowledge of them.

Method used

By acquiring the original image of the code image label to be identified, all graphic contours are determined and the target contour where the micro-coded code image is located is found. The scanning area is determined based on the shortest distance from the center of the micro-coded unit contour to the target contour. The number of micro-coded units in the scanning area is counted, and the area with the largest number is taken as the target recognition area.

Benefits of technology

It improves the recognizability of micro-coded code images, helps users to scan and identify correctly, and enhances the recognition and decoding effect.

Abstract

The application discloses a kind of special micro-encoding code chart identification area determination method, device, equipment and medium.The method comprises: obtaining the original image of the code chart label to be identified;Determine all graphic contours in the original image, and determine the target contour where the micro-encoding code chart is from each graphic contour;Determine each micro-encoding unit contour in the target contour, and determine the scanning area of the corresponding micro-encoding unit based on the shortest distance from the center of each micro-encoding unit contour to the target contour;The number of micro-encoding units in each scanning area is counted, and the scanning area with the most number is taken as the target identification area.Through the positioning of target contour, the content other than code chart in code chart label can be excluded, and then by positioning the specified scanning area in the target contour, a relatively more suitable identification area for identification can be obtained in the case of special encoding, so that the user can be better guided to correctly scan and identify the micro-encoding code chart based on the area.
