Abstract

The present invention discloses an omnibearing bar code identification device and method. The device comprises n cameras, an image acquisition and processing module, a data transmission module and a power supply management module. The cameras are all connected with the image acquisition and processing module, the image acquisition and processing module is connected with the data transmission module, and the power supply management module is connected with the cameras, the image acquisition and processing module and the data transmission module separately and is used to supply power to the cameras, the image acquisition and processing module and the data transmission module. The method comprises the steps of acquiring the side surface images of different directions shot by the n cameras; pre-processing the images; correcting the images; splicing the images; analyzing the bar codes; and transmitting the bar code information. According to the present invention, with the arrangement of the plurality of cameras, the bar code information pasted in any direction of the product side surfaces can be identified via software, and the omnibearing bar code identification device and the omnibearing bar code identification method have the characteristics of being fast in speed, low in power consumption, high in accuracy and good in versatility.

Description

technical field [0001] The invention belongs to the technical field of image recognition, in particular to a barcode recognition device and method. Background technique [0002] Barcode scanning equipment is a reading equipment used to read the information contained in the barcode. It uses the principle of optics to decode the content of the barcode and transmit it to a computer or other equipment. Barcode reading equipment is widely used in commercial POS cash register systems, express delivery, warehousing, logistics, books, medicine and other fields. [0003] At present, some enterprises have used the product barcode management method to correspond the barcode to each station. After the completion of each station, the semi-finished products are pasted (sprayed) in the designated area and flowed into the production line for subsequent processes. After the multi-station is completed, identify multiple barcodes in the designated area, selectively integrate multiple barcode ...
