    Abstract: An apparatus for optical inspection of objects, in particular cans. The apparatus includes an inspection station, a lighting system, and a camera directed towards the inspection system to capture an image of the lateral surface of the object to be inspected. A Fresnel lens is associated with the lighting system to direct a beam of light rays collimated towards the object to be inspected, located in the inspection station. A further Fresnel lens is positioned to face the object to be inspected, located in the inspection station and directed in such a way as to make the collimated light rays converge on the object.

    Abstract: A method for inspecting the side wall of an object includes the following steps: transporting the object on a conveyor; receiving the object to be inspected in an inspection station positioned along the conveyor, where the axis (A) of the object is oriented along a longitudinal direction (D); capturing a first image through a first camera which views the object from above along an optical path which has at least one component that is parallel to the longitudinal direction (D); deriving a three-dimensional representation of the side wall of the object based on the first image and on reference data; capturing a second image, representing a portion of the side wall of the object, the second image having perspective distortion; deriving a third image representing the portion of the side wall of the object, the third image being without perspective distortion.
