ABSTRACT:
To detect damage in the bottom region of a plastic bottle a picture of the bottom region is taken by means of a camera. The resulting image is then tested for brightness pixel by pixel in a predetermined inspection area. Large deviations of the test curve from the average value are indicative of a damaged bottle. The process is meaningful, and it can be carried out on existing bottle inspection machines.
