Problems solved by technology

However, this method has high requirements on the image quality of the barcode. In actual scenes, complex lighting, shaking, focusing and other factors will make it impossible to accurately locate the barcode area based on the barcode image captured by the camera, thus making the barcode recognition accuracy relatively low. Low

Abstract

The invention provides a barcode locating method, apparatus and device. The method comprises the steps of obtaining a barcode image obtained by scanning; performing preset shape region sampling on thebarcode image; by utilizing at least one pixel difference feature of each preset shape region obtained by sampling, detecting whether a square block obtained by sampling corresponds to a barcode region or not, wherein the pixel difference feature reflects a relative gray difference of two pixel points in the preset shape region; and combining the preset shape regions corresponding to the barcoderegion to obtain the barcode region. In the way, the requirements of barcode identification on barcode image quality can be lowered and accurate barcode locating is realized.

Description

【Technical field】 [0001] The invention relates to the field of computer application technology, in particular to a method, equipment and device for locating barcodes. 【Background technique】 [0002] At present, camera-based barcode recognition is popular, and users can use functions such as "scan" to realize product query, payment, and add contacts, such as figure 1 shown. The existing barcode recognition methods are mainly based on image binarization, such as segmentation based on image gray threshold, edge enhancement and extraction and other technologies. However, this method has high requirements on the image quality of the barcode. In actual scenes, complex lighting, shaking, focusing and other factors will make it impossible to accurately locate the barcode area based on the barcode image captured by the camera, thus making the barcode recognition accuracy relatively low. Low. 【Content of invention】 [0003] In view of this, the present invention provides a method...
