Abstract: The invention provides an apparatus and method for calibrating a dispensing system. A dispenser dispenses a controlled quantity of material into a container for receiving material. A system, preferably a vision system comprising an image capturing device and an imaging system, is adapted to capture an image of a physical dimension of a quantity of dispensed material in a given time. The physical dimension may be a width of a top surface area, a height or a cross-sectional area of the dispensed material. A calibrating system is adapted to calculate a volume of the quantity of material based upon said physical dimension.
