Object e.g. ashlar-shaped packet, expansion determining device, has light source and camera arranged adjacent to outer contour of object and adjacent to contact area such that image of object is displayed on side edge of side surface

摘要

The device has a light source (6) aligned in an object direction, and an image camera (8) aligned in the object direction, where the light source and the image camera are spaced apart from each other. The light source and the image camera are arranged adjacent to an outer contour of an object (1) and laterally adjacent to a contact area (4) in such manner that an image of the object is displayed on a side edge (11a) of a side surface, which corresponds to an object height that is determined based on the side edge.
