Problems solved by technology

[0003] However, the barcode that needs to be recognized is often on a more complex background. Before the recognition and decoding, a positioning algorithm must be added to extract the barcode part from the overall background image. It is obviously difficult to achieve the goal by starting with grayscale features and morphological features

Abstract

The invention provides a bar code positioning method, a storage medium and a computer. The bar code positioning method comprises the following steps: acquiring a grayscale image comprising a bar code; rasterization is carried out on the gray level image; calculating a texture feature value of each grid, wherein the texture feature value of each grid is a ratio of a row gray level change mean value of the grid to a column gray level change mean value of the grid; analyzing the texture feature value of the grid to obtain a bar code area; and cutting according to the circumscribed rectangle of the grid set of the bar code area to obtain the bar code area. In this way, illumination influence and background interference are avoided, the bar code area can be accurately positioned in the whole image, the speed is high, and the overall robustness of positioning is good.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a barcode positioning method, a storage medium and a computer in a complex background. Background technique [0002] Barcodes are widely used in society. Although 2D barcodes have stronger storage capacity and reliability, 1D barcodes still have the advantages of low cost and easy production. Therefore, in industrial production or some specific industries, barcodes are often more efficient. meets requirements. [0003] However, the barcodes that need to be recognized are often on a complex background. Before recognition and decoding, a positioning algorithm must be added to cut out the barcode part from the overall background image. However, considering factors such as lighting conditions and background diversity, from the image It is obviously difficult to achieve the goal by starting with grayscale features and morphological features. [0004] Therefore, it is necess...
