Abstract

The invention provides an image reading method used for dynamically configuring a decoding parameter and a device. The method and the device are applied to an electronic device. The electronic device comprises a camera and a display. When the target electronic device is used to decode a current dot-matrix two-dimensional code, a preset decoding parameter which matches the target electronic device is acquired to configure the target electronic device. The decoding parameter is suitable for the target electronic device. When the configured target electronic device decodes the current dot-matrix two-dimensional code, the code point of the dot-matrix two-dimensional code in an acquired preview image is appropriate. The success rate of the target electronic device for current dot-matrix two-dimensional code decoding is ensured.

Description

technical field [0001] The present application mainly relates to the technical field of image recognition, and more specifically relates to an image recognition method and device for dynamically configuring decoding parameters. Background technique [0002] At present, QR codes have been widely used in information acquisition, website redirection, advertisement push, mobile e-commerce, anti-counterfeiting traceability, discount promotion, member management, mobile payment, etc. By scanning the face, you can obtain a large amount of information it carries, which is very convenient, practical and safe. [0003] Among them, the dot matrix two-dimensional code is a commonly used two-dimensional code, which is encoded by the different distribution of black and white pixels. Represents binary "0". In practical applications, it is usually scanned by the camera of an electronic device, so as to realize the decoding of the dot matrix two-dimensional code. [0004] However, in the a...
