Abstract:

To recover the 3D deformable structure from an un-calibration image sequence, a factorization reconstruction method for 3D deformable reconstruction is presented. Based on the low rank constraint on the image matrix, the projective reconstruction can be obtained by single value decomposition. By using the orthogonality of the projective matrix, the Euclidean reconstruction is upgraded from projective reconstruction. The innovation of the method is that the solving of the 3D non-rigid reconstruction is linear and that all the images and the image points are treated uniformly. The experiments with both simulated and real data show that the method presented in the paper is efficient.
