Intelligent laser cutting system provided with master-slave camera and cutting method thereof

The invention provides an intelligent laser cutting system provided with a master-slave camera and a cutting method thereof. The intelligent laser cutting system provided with the master-slave camera comprises a worktable, a small head stock, a local slave camera and a laser head, a global master camera, a monitoring terminal, a main controller and a driving motor, wherein the worktable is positioned at the bottom; the small head stock is arranged above the worktable; the local slave camera and the laser head are fixedly arranged with the small head stock; the global master camera is hung on the top; the monitoring terminal is used for monitoring images of the global master camera and the local slave camera; the main controller is electrically connected with the global master camera; the driving motor is controlled by the main controller and is connected with the worktable and the small head stock; a lens visual field of the global master camera comprises the entire worktable; the driving motor drives the small head stock to move; and the local slave camera moves synchronously along with the small head stock and performs local image acquisition on the worktable. High-efficiency and high-accuracy laser cutting processing can be performed on various applicable objects without depending on the accuracy of the main controller of a laser cutting machine and a mechanism.
