Automatic control system with computer-vision bar code identification function

Abstract

The invention relates to an automatic control method with a computer-vision bar code identification function. The method comprises the following steps: carrying out pre-settings on the requirement ofprinting bar codes, wherein the pre-settings comprise the steps of reading a printing template file and setting a labelling number; after judging that objects approach, weighing the objects through aweight information acquisition module, and generating label contents with graphic identifiers from the weight information of the objects according to the printing template file, printing labels, and bonding the labels onto the objects; acquiring the images of the labels through a camera, and judging whether the information of label files is the same as the label contents set in the previous step through the control system; separating out the objects with wrong label contents; and repeating the abovementioned steps until the objects with correct label contents reach the set labeling number.

Description

technical field [0001] The invention relates to the field of automatic labeling control, in particular to an automatic control system with a computer vision barcode recognition function. Background technique [0002] In the era of the Internet of Things economy, in order to be able to trace the source of each product, each product needs to be packaged, and consumers can know all the information of the product, such as the manufacturer, origin, shelf life, production date, nutritional content, and other related information . Labels are an effective way to load this information, especially the barcode on the label. The label is usually attached to the outer packaging of the product, and the labeling machine is a device specially responsible for realizing this function. [0003] Labeling machines usually have an online automatic labeling function, in which the automatic labeling control system is the core of the labeling machine, which controls all the components of the entire...

AI Technical Summary

Problems solved by technology

The current labeling machine control system is mainly based on the industrial computer, which realizes functions such as sensor information detection and label information printing, and the cost of the industrial computer is relatively high.

In addition, whether the barcode in the printed label is correct is crucial to the accurate identification of future items. Most of the current labeling machines do not verify whether the barcode in the printed label is consistent with the set barcode, or need to manually pass the scanner to complete the detection , cannot be automated, and the scanner increases the cost of the entire labeling machine
