ABSTRACT:
An automatic optical inspection system includes a rotary device for driving an object to rotate. At least one line-scan camera is implemented for generating two-dimensional planar images of cylindrical surfaces of the object. A device for detecting defects is operable to generate the two-dimensional planar images of the cylindrical surfaces of the object according to a normalized grayscale absolute difference inspection method.
