With the continuous expansion of application scenarios, the traditional method of laser scanning to obtain barcodes has been difficult to meet people's daily use needs-and, in traditional methods, barcodes are generally read by humans with special decoding equipment such as laser scanners. Take it, the efficiency is relatively low, and it is more dependent on special equipment, and the time cost and personnel cost are high

A method for locating a barcode area, first judges whether it is a high-frequency area, and if it is a high-frequency area, counts the distribution of gradient directions in the area, then makes further judgments, and finally accurately locates the barcode area. Therefore, the whole processing process includes two major steps: coarse positioning and precise positioning; in the coarse positioning step, it mainly completes such as pyramid image construction, high-frequency region determination, regional gradient direction determination and region mapping to the next pyramid region; Mainly based on the rough positioning area, optimization and adjustment are carried out in order to obtain a more accurate barcode orientation and provide better pose input for barcode decoding.
Description
technical field [0001] The invention relates to a method for locating a barcode area. Background technique [0002] With the widespread availability of mobile camera devices and scanners, it is becoming easier and easier to obtain digital pictures. At the same time, in people's daily production and life, bar codes are playing an increasingly important role in terms of commodity purchase, circulation, consumer payment and other aspects. With the continuous expansion of application scenarios, the traditional way of obtaining barcodes by laser scanning has been difficult to meet people's daily use needs - and, in traditional methods, barcodes are generally read by humans with dedicated decoding equipment such as laser scanners. It is relatively inefficient, and it is more dependent on special equipment, and the time cost and personnel cost are high. [0003] In order to improve the convenience of barcode decoding, avoid the low efficiency of using laser scanners to scan manua...
