Abstract:
An apparatus for determining a size of an object on a conveyor, the object having a substantially rectangular shape, the apparatus comprising:first side determining means for determining a first locus of values corresponding to locations of a first side of the object as the object travels along the conveyor in a direction perpendicular to the first side determining means;second side determining means for determining a second locus of values corresponding to locations of a second side of the object as the object travels along the conveyor in a direction perpendicular to the second side determining means;third side determining means for determining a third locus of values corresponding to a height of the object;a first capture buffer for receiving the first locus of values;a second capture buffer for receiving the second locus of values;a third capture buffer for receiving the third locus of values;a processor configured to receive the first locus of values and to determine a first side of the object as having a first linear characteristics, the processor configured to receive the second locus of values and to determine a second side of the object as having a second linear characteristic, and the processor configured to receive the third locus of values and to determine the height of the object,wherein the processor outputs data corresponding to a size of the object based on the determined first side, the determined second side, and the determined height of the object.
