ABSTRACT:
Method for determining the volume of an object arranged on a flat background surface. The object is scanned using radiation in a predetermined pattern, the radiation reflected by the object is detected by a radiation pick-up means, the detected radiation is compared with radiation reflected by the background surface, and the volume of the object is computed from the comparison. A representative device determines the mass of a fish carried on a conveyor.
