Abstract

The invention discloses a positioning method of a bar code area and an apparatus thereof. In the prior art, positioning bar code area accuracy is low. By using the method and the apparatus of the invention, the above problem is solved. The method comprises the following steps of segmenting a plurality of subdomains in an area to be detected; and positioning at least one first area in the plurality of segmented subdomains, wherein each first area satisfies the following conditions that at least 3 scanning lines are determined in the first area along a bar code direction; and a ratio of the most wide stripe and the most narrow stripe of the at least 3 scanning lines is less than a first setting threshold; the at least 3 scanning lines are included in at least 5 scanning lines in the first area along the bar code direction; and the at least 5 scanning lines equally divide the first area. The ratio of the most wide stripe and the most narrow stripe of the scanning lines is used to position the plurality of subdomains acquired through segmenting the area to be detected. When a coding characteristic of a bar code is missing, positioning of a bar code area is not influenced and accuracy of bar code area detection is increased.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a method and device for positioning a barcode area. Background technique [0002] In the barcode detection based on the computer vision system, how to accurately and efficiently locate the barcode area in the area to be detected has always been an important research topic. [0003] In the prior art, after the area to be detected is divided into multiple areas, the coding characteristics of the barcode itself are used to locate the multiple detection areas after division. When the coding characteristics of the barcode are dirty or missing, although the content of the barcode It has not been damaged, but the lack of coding features will cause positioning errors and affect the accuracy of positioning. Contents of the invention [0004] The object of the present invention is to provide a barcode region positioning method and device to solve the problem of low detection accuracy of t...
