Abstract
An optical inspection method for containers. A container is at least partly illuminated or transilluminated with light of an illuminating device and captured from different viewing directions (R4-R6) as a camera image in each case by at least one camera. In a first image analysis step, first image information of a first inspection zone (A) of the container, for example a stain on a container front face, is ascertained from at least two of the camera images by stereoscopically pairing image points. In a second image analysis step, an individual camera image of the two camera images is analyzed, wherein the first image information is first excluded and second image information of a second inspection zone (B) of the container, for example a crack of a container rear face, is then ascertained.
