Abstract
A system and method for determining volume of a runtime object with a vision system is provided. A plurality of vision sensors are arranged so that the fields of view (FOVs) of the plurality of vision sensors collectively view features associated with volume determination of a runtime object. Each of the displacement sensors generates range images from sequences of analyzed images, each producing a single row of the range image. An ignoring volume is subtracted from the measured range image based upon one or more dividing planes as they appear in the viewing/imaging perspective of each displacement sensor. Negative subtraction results are substantially nulled. The resulting representative range images are used to calculate the volume of a portion of the object, as sectioned by the diving planes. Each volume result is summed/added to derive the overall summed volume of the runtime object.
