The invention discloses an intelligent numerical control machine tool based on image processing. The machine tool comprises a machine tool body, an electric execution mechanism, a servo drive device and a control system, wherein the control system comprises an image collecting device, an image storing unit, an edge detecting module, an image processing device, a first data storing unit, an automatic rectangular coordinate system generating module, a coordinate system loading module, a coordinate data measuring module, a second data storing unit, a coordinate data loading module, a coordinate system conversion module, a controller, a work parameter detecting unit, a memorizer, a parameter setting unit and a display device. The controller controls the electric execution mechanism to machine a workpiece according to the outline of a formed product after coordinate conversion. The memorizer, the parameter setting unit and the display are connected with the controller. The machine tool is reasonable in design, simple and convenient to use and operate, good in use effect and high in intelligent degree, and can effectively solve the problems that an existing numerical control machine tool is low in intelligent degree and low in machining efficiency and machining precision, and machining diagrams need to be drawn in advance.
