Gray level co-occurrence matrix-based arbitrary bar code positioning method, server, storage medium and system

Abstract

The invention provides a gray level co-occurrence matrix-based arbitrary bar code positioning method, a server, a storage medium and a system, and the method comprises the following steps: obtaining an original image containing a bar code needing to be positioned, and determining the texture features of different regions in the original image; pre-extracting texture feature ranges of various code systems; determining an area containing any bar code in the original image according to the texture feature ranges of various code systems; and determining an edge image of the bar code area, and determining four vertexes of the edge image to realize bar code positioning. The method has the following beneficial effects: 1) the method is suitable for positioning various code systems, is not limited by the type of the bar code, and can determine the type of the bar code while positioning; 2) a plurality of bar codes can be positioned at the same time; 3) the method can be suitable for complex backgrounds, such as uneven illumination or character backgrounds; and 4) texture feature ranges of various code systems can be completed through pre-training, so that the calculation time can be shortened, and the complexity of an algorithm is reduced.

Description

technical field [0001] The present invention relates to the technical field of visual image processing, in particular to a positioning method, server, storage medium and system for arbitrary barcodes based on gray scale co-occurrence matrix. Background technique [0002] In recent years, with the rapid development of mobile technology and the continuous deepening of the industrial automation industry, barcodes are widely used in industrial processing and manufacturing, logistics, transportation, Fields such as library management, food and drug production and supervision, and mobile payment. At present, the commonly used barcodes are one-dimensional code and two-dimensional code, and there are many barcode types (code systems). Value processing, and finally realize decoding to extract the contained information. [0003] The existing barcode positioning technology is often aimed at a single code system, and is often not suitable for positioning in complex backgrounds. Takin...
