Abstract
A system and method of the present invention allows the inspection of an object having an annular opening, such as a container or can, and uses a plurality of cameras that acquire grayscale images of arcuate sectors that together comprise a circumferential area within the opening. A processor is connected to the plurality of cameras for receiving the grayscale images and determining defects within the container based on contrast differences and grayscale intensity. The invention allows smart analysis of defects using qualitative inspections and quantitative measurements at higher speeds.
