Description

Technical Field

[0001] The utility model belongs to the technical field of visual code reading equipment, and in particular relates to a visual code reading equipment with improved clarity. Background Art

[0002] A barcode reader is a specialized code recognition device. Its code reading principle depends on the type of barcode reader. The code reading principles of optical barcode readers and machine vision barcode readers are different. The principle of an optical barcode reader is usually to use optical technology to project a beam of light onto the code, and then identify the code by detecting the light intensity reflected by the light. For example, a laser barcode reader emits a beam of laser light to scan the code, and identifies the content of the code by detecting whether the light is reflected back;

[0003] The principle of machine vision code readers is to identify codes from images through image processing technology and machine learning technology. Machine vision code readers generally obtain image data through cameras or image sensors, and then analyze the images through image processing technology to identify the code content.

[0004] However, when the visual code reading device is reading a code, if the lens inside the visual code reading device is contaminated, it is easy to cause the light emitted by the visual code reading device to be unable to be received, resulting in errors in the signal received by the visual code reading device.
