Improvement on Zhang's Camera Calibration

Abstract:

This paper presents an improved initial guessing method for the famous Zhang's camera calibration method for a moving camera. Given three or more known points in a scene, we can compute initial guessing values for maximum likelihood estimation for varying focal camera calibration. This method is useful in structure from motion, which needs consecutive video camera calibration using a known camera distortion.
