The technical scheme is as follows:

For the problem of improving the data acquisition recognition rate in the project, the key is the definition of the acquired image and the maturity of the deep learning model. In the scheme, in order to improve the definition of the acquired image, the inventor uses a group of annular light sources and a group of coaxial light sources to be added at the front end of the camera when an operator takes a photograph of the front end of the code, the two groups of light sources are connected with a light source digital controller, the illuminance and the contrast of the light sources are adjusted according to the bar code printing conditions of different outer package peritoneum, and the conditions of light reflection, consistent background color, shallower code printing and the like are recorded by adopting codes so as to achieve the best recognition effect.
