Problems solved by technology
[0002] As an important verification method for sorting, matching, and categorizing of goods, barcodes are used in many fields, but due to contamination or missing information during transportation and sorting, it will bring a lot of problems to the subsequent sorting and categorization work. Inconvenient, although some scanning devices are equipped with the function of supplementing missing information, they cannot adapt to the information supplementing process of missing one-dimensional barcodes and two-dimensional barcodes in complex environments, which urgently requires those skilled in the art to solve corresponding technical problems

The invention provides a working method for intelligently acquiring complementary pixels for an information missing bar code, which comprises the following steps: S1, acquiring complete information ofthe bar code, or verifying the complete information of the bar code according to characters at the bottom end of the bar code, carrying out true bar code information judgment when the verification information is consistent, if so, re-extracting a new bar code to carry out information judgment; S2, extracting a bar code with missing information, complementing the information through a difference algorithm, performing data verification on the bar code complementing the information, judging the consistency of characters at the bottom of the bar code and a bar code image, and performing image enhancement on the matched bar code; and S3, rotating the bar code subjected to image enhancement for bar code verification, completing an error correction process of the bar code, performing matching operation on letters, numbers and line segments by a regular matching method, determining a coordinate position of missing information of the corresponding bar code, and uploading the coordinate position to a cloud.
Description
technical field [0001] The invention relates to the field of image recognition and analysis, in particular to a working method for intelligently acquiring complementary pixels for barcodes with missing information. Background technique [0002] As an important verification method for sorting, matching, and categorizing of goods, barcodes are used in many fields. However, due to contamination or missing information during transportation and sorting, it will bring many problems to subsequent sorting and categorization. Inconvenient, although some scanning devices are equipped with the function of supplementing missing information, they cannot adapt to the information supplementing process of missing one-dimensional barcodes and two-dimensional barcodes in complex environments, which urgently requires those skilled in the art to solve corresponding technical problems. Contents of the invention [0003] The present invention aims at at least solving the technical problems exis...
