The present application relates to the field of image recognition technology, and discloses a method for acquiring a code-scanning image, including: acquiring an image to be scanned by a camera; determining the first brightness value of the image to be scanned; combining the first brightness value with the preset Compare the second brightness value to obtain the comparison result; adjust the scanning code parameters of the camera according to the comparison result to obtain the adjusted scanning code parameters; the scanning code parameters include gain and exposure value; obtain the scanning code according to the adjusted scanning code parameters image. In this way, the comparison result is obtained by comparing the first brightness value with the preset second brightness value, and the scanning parameters of the camera are adjusted according to the comparison result, which can improve the degree of automation, thereby obtaining a clear barcode image and improving The success rate of decoding barcode images. The application also discloses a device for acquiring a code-scanning image, a code-scanning device, and a storage medium.
Description
technical field [0001] The present application relates to the technical field of image recognition, for example, to a method and device for acquiring a code-scanning image, a code-scanning device, and a storage medium. Background technique [0002] Barcodes are graphic symbols used to represent various data information, and code scanning equipment is a collection and conversion device that restores these graphic symbols into data information. Barcode recognition technology has been developed for many years, and code scanning equipment is rapidly being widely used in many industries and applications. [0003] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in related technologies: [0004] In the prior art, in the case of poor lighting, it is necessary to manually adjust the camera parameters of the code scanning device to obtain a clear barcode image, and the degree of automation is poor. Con...
