ABSTRACT:
A method for determining the position of an object located on a carrier relative to a normal position, in an automated production process includes reflecting a light beam off an object and its immediate surroundings, separating a ray path of rays reflected by the object from a ray path of remaining reflected rays with different reflection surfaces of the object and its immediate surroundings, passing on the ray path of the rays reflected by the object for evaluation, and determining the position of the object based on brightness contrast between the rays reflected by the object and by its immediate surroundings, and a device for carrying out the method.
