Embodiment Construction

[0095] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0096] figure 1 It is one of the flowcharts of the two-dimensional code image recognition method in the embodiment of the present invention. like figure 1 As shown, the method includes the following steps:

[0097] Step 101, acquire a sub-image whose contour line nesting level is equal to the first value from the image to be recognized.

[0098] In the embodiment of the present invention, the electronic device receives the user's instruction to scan the two-dimensional code, and turns on the camera to scan the image to be recognized. After scanning, the electronic device obtains the image to be recognized, and then performs edge detection on the image to be recognized and extracts the edge part to obtain a contour image of the image to be recognized. Recognize that there are multiple nested contour ...

Abstract

The embodiment of the invention provides a two-dimensional code image recognition method and device, electronic equipment and a readable storage medium. The method comprises the following steps: obtaining a sub-image of which the number of nested layers of a contour line is equal to a first value from a to-be-recognized image; selecting the sub-images of which the pixel points of all the connectedregions meet the discrete characteristics and the preset proportional relation at the same time as positioning images, wherein the connected regions are regions formed by pixels which have the same pixel value and are adjacent in position in the sub-images; and under the condition that the number of the positioning images is a second value, taking a region where the minimum rectangle capable of covering each positioning image is located as a to-be-recognized two-dimensional code image. By means of the method, the positioning image of the two-dimensional code can be screened out step by step accurately, so that the position of the two-dimensional code image is accurately positioned, the accuracy of two-dimensional code recognition is improved, and the stability and safety of services are guaranteed.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a two-dimensional code image recognition method, device, electronic equipment and a readable storage medium. Background technique [0002] QR code is a very popular coding method on mobile devices in recent years. It can store more information and represent more data types than traditional barcodes. QR codes can undertake various services such as login, user identification, payment, sharing and attention in mobile applications, so recognizing QR codes is a must-have capability for mainstream applications. [0003] At present, most mobile applications use some open source QR code recognition frameworks, but these recognition frameworks are relatively old and cannot be applied to all kinds of QR codes. The existing recognition framework uses the method of finding the three figures with the closest area to identify the anchor points in the two-dimensional code image, but now some tw...
