Abstract
Embodiments of the invention provide a system and method for a visual inspection process, in which images of objects on an inspection line are automatically grouped into clusters based on the appearance of the object in the images. The clustered images create a broad database of images that can be used as a reference for inspected items having different appearances, which ensures that all parts and appearances of an inspected object can be identified and inspected, thereby increasing the success of defect detection and substantially minimizing false detection of defects.

A visual inspection method comprising:
- detecting an object in a plurality of set-up images of an inspection line, in each set-up image the object conforming to a criterion;
- grouping the images into clusters according to values of the criterion;
- detecting the object in an inspection image of the inspection line;
- comparing the inspection image to a cluster according to a value of the criterion of the object in the inspection image;
- and
- detecting a defect on the object in the inspection image based on the comparison.
A system for visual inspection, the system comprising:
- a processor in communication with a display, the processor configured to
- receive an image of an object on an inspection line,
- detect the object in the image,
- assign the image to a cluster based on appearance of the object in the image,
- determine a status of the cluster, based on a determination if the cluster achieved a complete representation of the object, and
- determine whether or not to apply an inspection algorithm on the image based on the status of the cluster, thereby achieving inspection of some objects before all clusters achieved complete representation of the object.
