VISION RECOGNITION SYSTEM FOR PRODUCE LABELING

摘要

A vision recognition system is provided for use with a high speed, automatic produce labeling machine. The system uses laser profiling to direct a sheet of light transversely to the longitudinal axis of a produce feed conveyor. The sheet of light periodically impacts, and generates laser profiles of, the surfaces of the produce items, such as pears, being fed by the conveyor to one or more labeling machines. The laser profiles are used to generate real world (x,y) coordinates of the domes of the incoming produce items, which are passed to the labeling machine or machines. Real world height (or z) coordinates may also be created and passed to the labeler.
