ABSTRACT:
A part tracking system comprised of an array of photoelectric sensors positioned at various angles with respect to a conveyor transporting parts such as pieces of poultry to create a field of detection. The angle arrangements of the array of photoelectric sensors circumscribes the parts with lines of varying angles to approximate the part outline or closed line integral with a polygon. As a part is conveyed through the array of photoelectric sensors each transition of the sensors provide a side of the polygon that circumscribes the part. From this the vertices of the polygon can be determined which allows the centroid and angle of the major axis of the part to be calculated thereby providing the coordinates for the part's location on the conveyor. The coordinates are then conveyed to a robotic controller which manipulates an end effector to grasp the part.
