description The invention belongs to the field of hot-rolled strip steel flying shear control engineering, and relates to a hot-rolled strip steel optimized shearing method based on machine vision. The method is mainly combined with a machine vision principle, non-contact measurement is performed on a strip steel end deformation part caused by rough rolling on a hot rolling production line, optimization control is performed on a flying shear system through a fuzzy self-tuning PID controller, and the method comprises the following operation steps: 1) collecting a strip steel end image; 2) processing image information; 3) obtaining a three-dimensional contour; 4) performing three-dimensional convex hull operation; 5) making a fuzzy self-tuning PID controller decision; 6) transmitting a shearing signal by the controller; and (7) shearing by an executing mechanism. Based on a machine vision detection system, the three-dimensional profile of the end of strip steel is obtained in combination with an image processing unit, a fl
