This article describes a method to inspect items by capturing several images of the item under different external conditions and combining them mathematically to increase the amount of information discerned by the vision system. Vision inspection systems minimally consist of a vision processor, at least one video camera, and a subject item to be inspected. The item is to be inspected by the vision system, and the system will determine whether the item is good or defective. Current vision inspection systems operate by focusing the video camera on an area of interest from the item. A single image of this area is captured by the camera, digitized, and then processed by the vision processor. A single image plane is used for each area to be inspected of the item.
