Abstract: The present invention discloses a system for smart camera image calibration, comprising a calibration card, a size marking on the calibration card, and a calibration image on the calibration card. A method for smart camera image calibration comprises calibrating a vision system to a size marking, capturing a calibration verification image, and verifying the calibration verification image based on the size marking. A smart camera calibration system comprises a vision system, a first calibration parameter programmed into the vision system, a calibration card comprising a size marking, and a calibration image, wherein the calibration image is shown on the calibration card and in the vision system, wherein the calibration image substantially corresponds to at least some portion of a product, and wherein the size marking does not bear similarity to the at least some portion of the product.
