The invention discloses a copper strip surface defect identifying device for simulating a human visual perception mechanism and a method thereof. The device and the method have the advantages that various defects such as hollow, scratches, greasy dirt, deckle edges, gaps and the like possibly generated in processes of reproduction, storage and transportation of a copper strip can be identified, capacities of defect detection and classification on the surface of the copper strip are improved, moreover, the identifying accuracy and speed are increased, and the efficiency is high; and not only can requirements on surface information detection of the copper strip of the current enterprises be met, but also the device and the method are further suitable for surface detection of other materials such as steel plates and the like, the requirements of the enterprises on surface defect information detection and storage of the copper belt are met, and furthermore, the device and the method are also suitable for the defect detection of other materials and have wide application prospect and market value.
