1. A detection system for detecting at least one edge portion of an object in front of a dark background, the system comprising: an imaging device for generating at least one image of the object, the imaging device having a lens and a field of view; at least one auxiliary light reflective area that is structured and arranged for passively illuminating the at least one edge portion of the object, the at least one auxiliary light reflective area being remotely disposed from the lens and beyond the field of view of the imaging device; and at least one illumination device for actively illuminating the object and the at least one auxiliary light reflective area, whereby light reflected from the at least one auxiliary light reflective area results in the passive illumination of the at least one edge portion of the object.
