SYSTEM FOR RECOGNIZING ALPHANUMERIC COMPONENT OF MATRIX CODE ON SURFACE OF WORKPIECES Russian patent published in 2024 - IPC G01B11/24 G06F18/40 G06V30/224 

FIELD: computer engineering.

SUBSTANCE: invention relates to computer vision systems for quality control of printing codes of marking. System for recognizing the alphanumeric component of the matrix code on the surface of the workpieces includes a control device, illumination systems, high-speed cameras, detection sensors, software, conveyor; encoder, uninterrupted power supplies, local server with Ethernet switch. Control device is a programmable logic controller (PLC), the input of which is connected to the output of the detection sensors, having an information input/output port for two-way data transmission with an HMI system module, connected through an information input/output port to a switch connected to vision controllers, vision controllers are connected through information input/output ports to high-speed cameras and information output port, and are connected to the backlight complex input, each vision controller is connected to an Ethernet switch, wherein the software for processing the obtained images is made in real time.

EFFECT: shorter time for checking the level of quality of applying a matrix code, higher efficiency, and shorter production time.
