摘要
Abstract
The paper describes a simple and practical self-calibration method of estimating the intrinsic parameters of digital cameras for image-based rendering system. This method is based on tracking the image features through a sequence of images while the camera undergoes pure rotation, no a special calibration object required. We presume the optical center of the camera is changeless during its movements, then the image center can be estimated beforehand, and we suppose the camera change its focal length while rotating. We give experimental results using real image sequences, which illustrate the robust performance of the method.关键词
