【Abstract】 The architecture of a new on-line cold-rolled steel strip surface defect inspecting system is proposed, in which the area-array CCD camera imaging,the ge o me trio segmentation and the composition of data from diferent segments are used.The working principle of the system is explained. An advanced high-speed digital signal processor(DSP) is used as the platform for digital image processing,and a parallel multi-DSP master-slave signal processing system is adopted. it is of compact construction and with flexible function.This system is in on-line operation.更多还原
