The online can surface defect vision inspection system is designed to detect surface defects on cans in real time. It utilizes two or more specialized cameras each configured to inspect different areas of the can—including the inner top inner middle inner bottom outer surface and welding line.

The system employs high-contrast industrial cameras to capture detailed images of the cans. These images are transmitted to a computer via an image acquisition card. Specialized image processing software then analyzes the images to identify any defects. Defective products are accurately and automatically removed from the production line by the integrated ejection device.
