Description

TECHNICAL FIELD

[0001] The utility model belongs to bar code recognition technical field, concretely relates to a bar code recognition collection imaging device. BACKGROUND

[0002] ‌Bar code recognition is a process that uses computer vision technology to automatically analyze and process bar code images. Through optical scanning and digital encoding technology, the information in the bar code is quickly and accurately read and converted into a computer-recognizable data form. Bar code recognition technology is mainly based on the combination of optical scanning and digital encoding technology. When the bar code is irradiated by the light emitted by the scanner, the light will reflect or absorb according to the arrangement pattern of bars and spaces, forming a specific optical signal. These optical signals are then captured by the photoelectric transducer inside the scanner and converted into electrical signals, which are then analyzed by the decoder. According to the preset encoding rules, the system converts the high and low levels (representing bars and spaces) in the electrical signals into corresponding digital or character information.

[0003] Bar code recognition can be applied in various fields, but some bar codes are printed on metal surfaces. When the bar code is recognized by the recognition device, the bar code on the metal surface will easily reflect light, making it difficult for the recognition device to accurately recognize the bar code.
