    摘要： An improved lighting system which illuminates the parts with both generally collimated and diffused light simultaneously useful with machine vision systems. This lighting system allows determination of part identification, part location, part orientation about a vertical axis thereof as well as side-up orientation of the part. The parts are transported on a conveyor surface which is made of a translucent medium. However, such translucent medium does permit the viewing of the shadows cast by objects thereon. The light source is positioned directly over the parts being inspected. A camera is positioned below the conveyor surface. Residing between the collimated light source and the parts supported on the conveyor surface is a light-diffusing member. The light-diffusing member has a structure such that it permits a portion of the generally collimated light to pass therethrough without obstruction while simultaneously diffusing a second portion of light produced by the source of collimated light. The combination generally collimated light and diffuse light serve to cast a perimeter shadow of each part and illuminate any downward-facing part surfaces which are not in contact with the conveyor surface. The result is a shadow of different contrasts. Those portions of the parts in contact with the support surface are much darker than those portions of the parts which are elevated away from the support surface.

    摘要： A method and apparatus which can reliably inspect three dimensional objects resting on a surface such that part type, part location, side-up orientation, and orientation about a vertical axis can be determined with a single camera. The object to be inspected is supported on a support member which may be a conveyor. The support member possesses two specific optical characteristics. First, the support member must permit direct viewing therethrough of the object supported thereon without any significant loss of clarity. The support member must also be capable of diffuse reflection of a portion of the light incident thereon. A camera is positioned below the support member and a light source is positioned above the support member to back-light the object for the camera. That portion of the light diffusely reflected off the support member serves to illuminate any downward-facing surfaces of the object which are not in contact with the support member. Surfaces of the object which are in contact with the support member are darker than downward-facing surfaces of the object which are not in contact with the support member. A computer evaluates the image.
