Novel Approach to Determining Camera Motion Parameters
Department of Computer Engineering, Hakodate National College of Technology, 14-1 Tokuracho, Hakodate, Hokkaido 042-8501, Japan
We discuss the expression of space rotation in terms of complex numbers and present explicit formulas for computing the direction of the rotation axis and angle. These formulas are applied to determining camera motion parameters from two perspective views. Our approach requires only 3 space points and their physical distances from the camera to determine motion parameters. We compare the proposed method with other methods and check it numerically.
