“…By increasing the light intensity, the concave and convex parts of the printing surface appear white, so as to avoid some black spots around the two-dimensional code when converting the binary image, which makes the two-dimensional code unable to be parsed. Code images with enhanced light intensity, as shown in Figure 4, are in a state of high-quality recognition [11,12]. e incremental encoder is used as the input signal for acquisition, and the main control board composed of an ARM chip outputs the trigger signal of the code reader [13].…”

The tracking of raw materials, production, and circulation links is carried out using QR codes in cigarette products. Each link’s current data collection and correlation analysis are still in the research and development stage. When used in conjunction with the GD packing machine’s production process feature, the QR code reader serves as an acquisition element for the process of data acquisition and the associated design for the tobacco packets and boxes, and the software is used to associate the received data and correct process exceptions. The system satisfies the design requirements, according to the results of the field verification.
