CALIBRATING A DIMENSIONER USING RATIOS OF MEASURABLE PARAMETERS OF OPTICALLY-PERCEPTIBLE GEOMETRIC ELEMENTS

Systems and methods for calibrating a volume dimensioner are provided. In one embodiment, a calibration system comprises a predefined reference pattern comprising a plurality of optically-perceptible elements. The optically-perceptible elements have predefined measurable parameters and are separated from each other by predefined distances. The calibration system also comprises a dimensioner configured to capture an image of an object and calculate physical dimensions of the object from at least the captured image. The dimensioner is further configured to capture one or more images of the predefined reference pattern and calculate a ratio between one of the predefined measurable parameters and one of the predefined distances. The dimensioner is further configured to be calibrated based on the calculated ratio.
