The system comprises surface defect grabbing devices (10), a multichannel parallel processing device, a server (30), a mass memory (40) and a console (20). The surface defect grabbing devices (10) are installed above and below a plate and strip production line (A). The surface defect grabbing device (10) comprises multiple cameras (11) and a lighting device (12). Each one of the multiple cameras (11) is connected to a corresponding independent channel processing device in the multichannel parallel processing device. The multiple cameras can simultaneously acquire plate and strip surface images. All the independent channel processing devices in the multichannel parallel processing device carry out parallel processing on the acquired images so that the system guarantees defect detection accuracy and further improves real-time on-line detection efficiency of plate and strip metal surface defects.
