Description

To achieve the input of an accurate magnification image, calibration of the focal length is needed in an active camera system which can control the viewing angle (pan and tilt), zoom, focus, and iris. It is shown that, by the calibration with a zoom lens camera model we propose, good estimation can be made even when the number of the measurement points on a single plane is small and the error of image coordinates is large. In addition, we demonstrate that we can integrate the multi-magnification images at the image center easily by using the calibration results of our camera system.
