Machine vision grading and trimming of broccoli.

A system is described which can be used for grading broccoli heads by size, shape, colour and stem length. Using a mirror and a single camera, images are captured which hold both plan and elevation information, as well as information concerning floret brightness and colour. The information is processed in a PC486 computer. A series of algorithms are executed to determine size, shape, colour, missing or loose florets, attached leaves, doming of the head and stem length. The system achieves a total throughput of 5 heads per second. The processed data is used to determine the packing station to which the head is to be diverted, according to the market on which the produce is to be sold and the appropriate grade for that market. The market in turn determines the length to which the stem is to be cut prior to packing. Grading thresholds set within the programme are flexible, with the operator being given the facility to adjust the thresholds between grades according to the crop, varying market qualit

y tolerance and seasonal variations.
