Abstract

The invention provides a one-dimensional code online detection method, device and system. The method includes: when the box containing the one-dimensional code label passes through the strip light source area of ​​the camera, taking a picture of the box containing the one-dimensional code label; whether the photo is available; when the photo is available, clipping the one-dimensional code area in the photo to obtain a one-dimensional code image; performing image processing and decoding on the one-dimensional code image to obtain a one-dimensional code string; The one-dimensional code string is compared with the manually input one-dimensional code string; when the one-dimensional code string completely matches the manually input one-dimensional code string, the online detection of the one-dimensional code is successful , otherwise, the online detection of the one-dimensional code fails. The invention can avoid the problem of decoding failure and improve the decoding efficiency at the same time.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an online detection method, device and system for one-dimensional codes. Background technique [0002] The one-dimensional code label of the product contains all information such as the origin, type, production date, weight, size, etc. of the product. Both buyers and sellers can easily obtain all the above information of the product by scanning the one-dimensional code. Therefore, one-dimensional The correct identification and reading of the code is of great significance to the circulation of commodities. In order to ensure the correct identification and reading of the one-dimensional code, the online detection of the one-dimensional code of the product has become an indispensable link before the commodity circulation leaves the factory. [0003] The factory's existing one-dimensional code online detection process is as follows: figure 1 As shown: the box 5 containing t...
