FIELD: photography.SUBSTANCE: invention relates to a method of calibrating a camera. System and method for calibrating a camera are disclosed, comprising an energy source and a camera to be calibrated, wherein at least one of energy source and camera is mounted on a mechanical actuator so that it is movable relative to other. Processor is connected to energy source, mechanical actuator and camera and is programmed to control mechanical actuator to move at least one of energy source and camera relative to other through a plurality of discrete points on a calibration target pattern. Further, processor controls camera at each of discrete points to take a digital image and determines parameters of lens distortion on each image. Focal length of camera is determined including any lens connected to camera and an extrinsic camera position for each image is then determined.EFFECT: enabling efficient calibration of camera.20 cl, 2 dwg |
