Post-processing judgment and correction method for character plain code recognition result of aero-engine blade

Abstract

The invention discloses a post-processing judgment correction method for an aero-engine blade character plain code recognition result, which comprises the following steps: firstly, inputting a blade plain code OCR character recognition result, referring to an existing sample library containing all plain code characters and a historical library of recognized output characters, judging the OCR character recognition result through the post-processing judgment correction method, and if the result is correct, judging the OCR character recognition result through the post-processing judgment correction method; if not, outputting the original character as a correct result, and not performing correction processing; and if not, correcting the input OCR character recognition result according to the judgment and correction method provided by the invention, and finally outputting a correct character result belonging to the sample library. Through the application of the method, the judgment and correction of the automatic OCR recognition result of the leaf plain code characters can be realized, the accuracy of OCR plain code character recognition can be improved, the manual searching and checking process of a large batch of leaf materials can be reduced, and further the informatization and automatic management of the leaf materials in storage, logistics and assembly sites can be realized on the basis.

Description

technical field [0001] The invention belongs to the technical field of character recognition, and in particular relates to a method for post-processing judgment and correction of character plain code recognition results. Background technique [0002] Aeroengine blade materials are large quantities of parts with highly similar shapes. The selection and assembly process can only be manually identified and selected through the unique recessed characters engraved on the tenons of the blades. In the field of artificial intelligence, OCR character recognition technology is widely used in the field of text recognition, which recognizes valid characters by collecting images containing characters. However, the recognition of the recessed engraved characters on the surface of the aero-engine blade is easily affected by metal reflections and environmental interference, resulting in misrecognition, which in turn leads to unqualified component balance testing after assembly, and multiple...

Problems solved by technology

This invention only performs iterative deletion of characters containing Chinese characters (such as stomach food liquid), and then performs post-processing operations. One is that the character object is single and cannot cover the input characters of letters and numbers. The other is The processing of only deleting characters narrows the scope of the results, and it is easy to fall into local solutions
