Abstract: An apparatus for enabling geometric lens distortion calibration for a metric digital camera includes a turntable, a cage mounted on the turntable, and an array of targets disposed on the cage. The device provides distribution of image references points in three planes and is rotatable, allowing minimal movement of the camera being calibrated in three dimensions and reducing space requirements for calibration facilities.
