AI Technical Summary

Problems solved by technology

For camera modules with lower configuration, such as the camera modules that exist in a large number of low-end mobile phones, because they use fixed-focus lenses, the captured images are often blurred due to inaccurate focus
In this way, it is difficult for common barcode detection methods to determine whether a barcode is included in this type of barcode image.

Abstract

The invention discloses a bar code detection method and a bar code device. The bar code detection method includes searching at least two bar areas in an image and identifying endpoints of each bar area, and identifying whether the searched bar areas belong to the same bar code or not based on the searched endpoints of the bar areas. If the searched bar areas belong to the same bar code, the image containing a bar code can be judged. Due to the fact that whether an image contains a bar code or not can be judged through searching the bar areas and endpoints in the image, more accurate judge is achieved, and the effect of image definition is small.

Description

【Technical field】 [0001] The invention relates to the field of linear barcode recognition, in particular to a barcode detection method and device for determining whether an image contains a barcode. 【Background technique】 [0002] A linear barcode is also often called a one-dimensional barcode (1D barcode), which is a graphic identifier for expressing a set of information by arranging multiple black bars and spaces of different widths according to certain coding rules. At present, it is widely used in industrial and civil fields. Common linear barcodes include Universal Product Code (UPC code for short), European Article Number (EAN code for short), Japanese Article Number (JAN code for short), Code 25, Code 39, Code 128 and so on. [0003] Commonly used barcode scanning equipment is usually composed of light source (such as laser), optical lens, photosensitive device (such as CCD, CMOS, etc.), decoding logic circuit and I / O interface and other components. To put it simpl...
