Abstract
A method and a device for the identification of incorrectly orientated parts and/or parts departing from a predetermined master, the parts being moved by means of a conveyor means ( ) past at least one camera ( ) for registering the shapes of the parts. When there is a preset departure from stored masters values the respective part is identified as being faulty and/or removed. On the basis of image signals of the camera ( ) corresponding to the shape of the respective part a plurality of criteria are derived such as overall length, overall height, area, axial position, surface waviness, position of center of gravity. Such individual compared with the corresponding individual criteria derived from at least one master part. This means that with a relatively small memory requirement the parts may be reliably identified and more particularly significant fine structures may be distinguished.
