Because Conference matrices and Hadamard matrices are related to Paley matrices,in this paper we define the normalized Conference matrices and generalized normalized Hadamard matrices,and we show some special properties of them. Also we constructed a doubly even self-orthogonal code from normalized Conference matrix and a doubly even self-dual code from generalized normalized Hadamard matrix.

An iterative factorization method based on linear subspace for projective reconstruction is presented in the paper. It relies on the facts that the rows in the matrix including all the image points span the same linear subspace as the rows in the matrix including space points and the fact that any basis of the subspace can be regarded as projective reconstruction. The projective reconstruction and the depth factors are obtained based on linear iteration.
