Abstract

The real-time on-line checkout systems are wildly required to assure the quality of products. A product optical on-line product inspection system is designed based on the principle of image cross-correlation technique. The principle of this optical product inspection method is comparing the image of products on-line with the image of references. To enhance the effectiveness of the cross correlation, a Gaussian filter is introduced to weaken the intensity of the autocorrelation peak. For angle and position detection, ten referential images under different rotation angles are put on a circle position while the image of the object is shown at the center of the circle. The information of the direction and position of the object can be obtained immediately.
