Abstract(in English)	Various techniques have been studied in the past for algebraic camera self-calibration for reconstructing 3-D shapes from feature point correspondences over multiple images taken by uncalibrated cameras, using only linear computations. In this paper, we choose from among them the latest one that we regard as definitive and describe its computational procedure in detail. It consists of two stages: "projective reconstruction" for computing a 3-D shape up to projectivity and "Euclidean rectification" that transforms it to a correct shape. For the former, we adopt the "factorization" approach; for the latter, we impose the "dual absolute quadric constraint". We also introduce new techniques for improving accuracy and computational stability.
