摘要:
A lens inspection system 10 has two cameras 50, 51 for capturing plan and edge images views of a lens 20 and providing pixel data signals representative of the images. The pixel data signals corresponding to the plan and edge images are analyzed by a computer 70. The computer uses the pixel data signals to calculate the circumference of the image, the lengths of radii to circumferential pixels, and the bevel angle of the lens 20. Such data are compared to data stored in memory 710 and a visual display 74 indicates the difference between the image and the stored data.
