The author presents a quick and easy solution to the camera calibration problem of finding the scale factor that arises because of a difference between the scanning frequency of the camera sensor plane and the scanning frequency of the image capture board frame buffer. The method presented is based on the observation that the scale factor is related to the distortion in an image of a circle: this is a distortion that can easily be measured by considering the occluding boundary of a precisely fabricated sphere, such as a ball bearing. Implementation results are presented.
