Here is a demonstration of high-speed image inspection for cylindrical and cylinder parts.



In this demonstration, a cylindrical part is synchronized with signals from an encoder while rotating. Continuous images are captured with a horizontal resolution of several pixels and a vertical resolution of 2000 pixels. These images are then stitched together to create a continuous image of the entire circumference, similar to an open scroll, and are used to inspect for scratches, dents, foreign particles, dirt.

▲ Example of inspection results: An image of the entire circumference is generated from 195 partial images, allowing for the detection of outer and inner surface scratches in their actual proportions, without distortion.
