Blank head and tail tracking system for optimizing shearing

The utility model discloses a blank head and tail tracking system capable of optimizing shearing, which relates to the field of metallurgical automation control and comprises a roughing mill, a finishing mill and a flying shear, the roughing mill is used for rolling a steel plate into a plurality of intermediate blanks, and the flying shear is mounted between the roughing mill and the finishing mill and used for cutting off irregular heads and tails of the intermediate blanks. A machine vision positioning system in signal connection with the flying shear is arranged between the roughing mill and the flying shear, and the machine vision positioning system identifies the optimal shear line positions of the head and the tail of the intermediate billet through machine vision and identifies the real-time positions of the head and the tail of the intermediate billet when the intermediate billet passes through the flying shear; the flying shear is controlled to act according to the judgment result; according to the
