<p>A detection system and method for detecting an object such as a vessel or a cap on a vessel. The system includes an imaging device having a lens with a field of view for registering and processing an image of the object, an illumination device (s) for actively illuminating the object, a dark background portion, and an auxiliary light reflective area(s) for passively illuminating an edge portion of the object using reflections of illumination from the illumination device (s). The auxiliary light reflective area(s) is/are disposed adjacent to the dark background portion out of the field of view of the lens. Images of the object are subsequently compared to images of reference objects.</p> |
