We describe a method for estimating camera parameters from image sequences for image synthesis. The method consists of first establishing correspondence and then, estimating the parameters by fitting the correspondence data to a transformation model based on perspective mapping model and 3-D rotation and zoom. operation model. We show by simulations and experiments that the proposed method successfully estimates focal length from image sequence and explains very well the induced motion field of images undergoing camera operation: 3-D rotation and zoom, and significantly outperforms conventional estimation methods, especially for wide-angled images.
