CAMERA-CALIBRATION IN A COMPUTER VISION SYSTEM

摘要

In a camera arrangement of a computer vision system, camera calibration is effected on-line, i.e. while the camera is involved in a visual task. The calibration is carried out automatically whenever the camera undergoes a series of displacements relative to a fixed scene. The calibration method is based on the epipolar transformation associated with each displacement, using Kruppa equations to derive the calibration signals.
