Abstract
AbstractThis paper proposes a method for estimating rotation and slant angles with slant direction of a textured plane using spectral moments. When a textured plane rotates and slants, the 2D power spectrum also rotates and expands toward the slant direction. Thus, the spectral moments also change corresponding to the rotation and expansion. The rotation angle, slant angle, and slant direction of a textured plane can be derived from the comparison between the second‐order spectral moments of a standard image and those of a test image. We show the validity of the method in simulations using the synthesized images and in experiments using real images taken with a CCD camera. © 2003 Wiley Periodicals, Inc.
