AI Technical Summary
Technical Problem
The existing technology has insufficient anti-interference ability when there is dirt in the bar code area, resulting in low recognition rate and accuracy, and the bar code needs to be set in a fixed position, which has poor flexibility.
Method used
By identifying candidate line segments in the image to be processed and combining the first constraint combination and the longitudinal spacing constraint, the target page number stripe group is screened out to improve the anti-interference ability and recognition rate.
Benefits of technology
It effectively eliminates dirt and other interference factors, improves the recognition rate and accuracy of the bar code area, and enhances the flexibility of the recognition method.

Abstract
The invention discloses a page number recognition method, a printer, a readable storage medium and a program product, and relates to the technical field of image recognition, the method comprises the steps that a plurality of candidate line segments are recognized in a to-be-processed image, each candidate line segment comprises a plurality of target pixel points with the pixel value being a first value, and the target pixel points are selected from the target pixel points with the pixel value being a second value; the plurality of target pixel points are continuously arranged along the first direction; combining and filtering the plurality of candidate line segments according to a first constraint condition to obtain a plurality of first page number bars; grouping the plurality of first page number bars according to the initial positions of the plurality of first page number bars to obtain a plurality of first page number bar groups; according to a longitudinal spacing constraint condition, filtering the plurality of first page number bar groups to obtain a target page number bar group; and performing page number identification on the target page number bar group to obtain a target page number. The method and the device have the effects of improving the anti-interference processing capability of interference information such as smudginess in the strip-shaped page number area and improving the recognition rate and accuracy.
