Abstract

The embodiment of the invention provides a two-dimensional code extraction method, a two-dimensional code extraction device, a readable storage medium and terminal equipment. The related parameters ofthe two-dimensional code in the image are determined by using the framing parameters of the camera for collecting the image and the printing parameters of the two-dimensional code. Then, the area conforming to the related parameters is searched in the image. The area conforming to the related parameters is used as the two-dimensional code area, so that the two-dimensional code extraction accuracyis improved. The two-dimensional code recognition efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a two-dimensional code extraction method, device, readable storage medium and terminal equipment. Background technique [0002] With the popularity of two-dimensional codes, two-dimensional codes have also been widely used in the industrial field. An important link in the process of using the QR code is to recognize the QR code, and to recognize the QR code, it is necessary to extract the QR code from the collected image first. The current way to extract the QR code is: directly use A feature of a QR code (usually a specific graphic in a QR code) looks for a QR code in an image. However, due to the complex environment of the industrial site, there are often other background patterns around the location of the two-dimensional code, which will interfere with the extraction of the two-dimensional code. QR code recognition efficiency is low. Contents of the...
