AbstractA system for locating a feature of an object disposed in a frame includes a spot projector for projecting a spot in the general vicinity of the feature and an imaging device with a limited field of view. The spot projector is a precision device which projects the spot towards a preselected location on the frame. When the spot and the feature are in the field of view of the imaging device, the absolute location of the feature is determined from its selective distance to the spot. Provisions are also made for determining depth or relief information about the object.
