Problems solved by technology

[0006] However, the outer packaging of cigarettes is made of different materials, and the degree of burning of the laser code is different under different light sources and different brightnesses. The clarity of the laser code image is not the same. Under a single recognition algorithm, the recognition rate is also different
[0007] At present, there are relatively few laser code recognition system products at home and abroad. Even a few of them provide products that are recognized under a single light source and a fixed light source brightness, and a single algorithm. not ideal

Abstract

The invention discloses a 32-bit cigarette laser code recognition system based on embedded system and a recognition method thereof. The recognition system comprises a light source system, an image acquisition system and an algorithm module. The recognition method comprises the following steps: acquiring an initial imaging picture; calculating texture information of the current image through an image acquisition system; according to the primary texture information, the light source spectrum of the second imaging is adaptively selected and the exposure value of the selected light source spectrumis determined, and the secondary imaging is carried out. Calculating texture information of the second imaging again; according to the texture information of the second image, the adaptive selectionalgorithm identifies the cigarette laser code with high accuracy and displays it. Automatically selecting and adjusting the type and brightness of the light source based on the different materials ofthe cigarette, in any case, can clearly image; according to the imaging quality of the laser code, it can automatically fuse the results of a variety of laser code recognition algorithms to achieve the optimal recognition effect.

Description

technical field [0001] The invention relates to the fields of industrial camera CCD image technology, optical character recognition OCR technology, etc., specifically, an embedded 32-bit cigarette laser code recognition system and a recognition method thereof. Background technique [0002] Industrial cameras are also commonly known as video cameras. Compared with traditional civilian cameras (cameras), they have high image stability, high transmission capabilities, and high anti-interference capabilities. Most industrial cameras on the market are based on CCD (Charge Coupled Device) chips. camera. [0003] Industrial camera (CCD), full name in English: Charge-coupled Device, full name in Chinese: charge-coupled device. It can be called a CCD image sensor, also called an image controller. CCD is a semiconductor device that converts optical images into electrical signals. The tiny photosensitive material implanted on the CCD is called a pixel (Pixel). The more pixels conta...
