Abstract:
An automatic inspection system using barcode locator, which can inspect a colored surface of a first three-dimensional object having a barcode, comprising:a light source for uniformly illuminating the first three-dimensional object; an image-retrieving device for retrieving and analyzing three-dimensional images of the first object at various viewing angles; an operating and processing device for receiving three-dimensional images from the image retrieving device, segmenting the three-dimensional images, converting the three-dimensional images into two-dimensional images, connecting the two-dimensional images of various viewing angles to obtain a single two-dimensional image representing the first three-dimensional object, using a barcode in the single two-dimensional image to position the single two-dimensional image in a first predefined position and comparing the two-dimensional image with a reference object image previously stored in the operating and processing computer to find defects in the colored surface of the first three-dimensional object.
