Abstract

This paper presents a computer image processing system, which measures the thickness of the ALC block and inspects the defect on a real-time basis. The Image processing system was established with a CCD camera, an image grabber, and a personal computer without using assembled measurement equipment. The image obtained by the system was analyzed by a devised algorithm, specially designed for the enhanced measurement accuracy. For the realization of proposed algorithm, the pre-processing method that can be applied to overcome uneven lighting environment, and threshold decision method, and subpixel method are developed. from the experimental results, we could find that the required measurement accuracy specification is sufficiently satisfied using our proposed method.
