Character detection refers to the detection of confirming, distinguishing and judging the characters engraved on the product, and is widely used in the detection and confirmation of production information in all walks of life.
According to national regulations and convenient production management, the product must be marked with information such as the third period and the production number, but if it cannot be correctly read, identified and managed, then the production information will lose the significance of product traceability management for the producer. In order to quickly manage production information, the development of machine vision OCR inspection technology has replaced the traditional manual entry of low-quality inspection.
The third phase of the product, the production number and other circulating strings are an indispensable and important part of product information. This character information is very important to the product, but it also makes it more time-consuming and laborious to manage.
Test content: character detection of product number and model; Phase III testing of the product; Product packaging printing character content detection and product barcode content recognition.
Solution. The machine vision character detection system converts the characters into an image signal through an industrial camera, transmits it to the image software processing system, and converts it into a digital signal based on information such as pixel distribution and brightness. The image software processing system checks the string with the judgment string, provides character matching detection information and statistical data in real time, realizes automatic identification of production detection information, and avoids the occurrence of problems such as misremembering and omission.
In addition, in recent years, with the development of barcode technology, the use of commodity barcodes, the use of ** popular, for simple barcode reading can be solved by directly using a barcode reader. However, for the situation that the information such as barcode, ** and the third period are recorded on the label at the same time, the character detection and recognition system can also recognize the barcode and characters at the same time, and manage the product information in a unified manner.
Intelligence, automation, digitalization and informatization are the major trends in the development of the manufacturing industry in the future, and Sichuan Envision is committed to the intelligent transformation and digital upgrading of manufacturing factories. We firmly believe that through continuous efforts and innovation, we can achieve win-win cooperation with customers. If you have a vision inspection related need, please contact us.
