Abstract :
A simple method for lens calibration is presented. The method uses a fiducial disc and straightedge which are placed imprecisely within the field of view. Several inexpensive 6mm lenses and CCD cameras were used to validate the method. It is fast and accurate to a variance of less than half a pixel, which makes it a useful tool for computer vision.
