Abstract

A computer-implemented method of calibrating a camera, comprises the steps of: a. acquiring a video stream from said camera (CAM), and displaying it on a screen (DY); b. displaying on the screen, superimposed to the video stream, a representation of a target area (); c. detecting a calibration pattern () in the video stream and periodically check whether it fits within the calibration area; d. when the calibration pattern is found to fit within the calibration area, extracting an image thereof from the video stream; said steps a. to d. being iterated a plurality of times using respective target areas corresponding to different positions of a physical support () carrying the calibration pattern; and then e. estimating intrinsic calibration parameters of the camera by processing said images. A computer program product, computer-readable data-storage medium and computer system for carrying out such a method.
