Function description: The system can realize the precise position tracking of bar or sheet on the rolling line, improve the cutting position and length accuracy, improve the blank length detection accuracy, and comprehensively improve the yield of the production line.

Product description: Through the visual camera installed on the rolling line (the camera has set the distance coordinates), the precise position and speed of the head and tail of the rolling piece are identified, and the precise length of the billet is calculated, realize the accurate centering of the cutting edge and cut all kinds of control targets through the first-level real-time communication.
