Vision inspection of vehicle reflectors

A vision system for inspecting the presence of embossed prints on car reflectors makes a very interesting example of how knowledge of optics, lighting, and optical filters can be used to create an application that appear to be unfeasible at first glance.

The purpose of our system is to detect approved printing on car reflectors. The system consists of twin stations, which allows simultaneous control of the right and left reflectors. The project uses Datalogic’s cameras.

The inside of the reflector is made up of hundreds of tiny mirrors designed to reflect light in all directions. This design makes it very difficult to detect embossed overprint on the surface. Fortunately, thanks to the extensive knowledge and experience of our engineers, we have created a fail-safe inspection.
