Problems solved by technology

Moreover, in the existing barcode detection process, it is first necessary to locate the approximate area of ​​the barcode in the image, that is, the potential area containing the barcode, and then decode and identify the located area. These areas include both real barcode areas and false barcode areas. In the barcode area, especially when the background of the working condition is complicated, the pseudo barcode area is mostly
[0005] Since the identification of pseudo-barcode areas undoubtedly wastes a lot of computing resources, especially when the number of pseudo-barcode areas is large, the efficiency of barcode detection is low

Abstract

The invention provides a bar code detection method, device and system. The method comprises that an image which is collected by an image collector and includes image information of an object with barcode is obtained; a potential area including the bar code is located in the image; according to the preset number and a preset bar code characteristic screening manner, a candidate area to be decodedis screened from the potential area; the preset number is determined according to pre-configured decoding number and / or the frame rate of a code reading image collector; and the candidate area obtained by screening is decoded. Thus, the bar code detection efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a barcode detection method, device and system. Background technique [0002] Industrial barcode detection is the process of detecting barcodes carried on objects, so as to intelligently count the basic information of objects through automatic barcode detection. [0003] In the existing barcode detection system, such as figure 1 As mentioned above, the rollers 1 and 2 drive the conveyor belt 5 to transport and drive in the direction 8, and the conveyor belt 5 is loaded with objects 9, 10 and 11, and the surfaces of each object carry a number of barcodes, respectively labeled as 12, 13, 14, 15, 16, 17, 18 , 19 and 20, the photoelectric triggering devices 3 and 4 equipped on both sides of the left side of the conveyor belt 5 use the infrared ray 7 as a trigger signal, so that when the object passes, the infrared ray 7 is blocked from being emitted between the photoelectric ...
