Feature extraction and correspondence matching for camera self-calibration and motion estimation

摘要

Two problems must be solved in order to estimate the motion of an uncalibrated camera between two viewpoints. One is the determination of the camera's parameters and the other is the correspondence matching of features in images taken at different positions. In this paper, we propose a new technique to extract corner structures automatically in an image and then match the features between two images. The method proposed incorporates the correct matching of the image corners in a unified algorithm for camera calibration and motion estimation.
