The stereo image pair is acquired by a pair of calibrated cameras. Global disparity of foot is estimated at first. After the image pair is preprocessed automatically, using non-contact information-collecting technique and phase-correlation method, which is based on complex wavelet, surface matching with sub-pixel accuracy in the frequency domain is carried out. By taking order matching constraint, continuity constraint and correlation constraint together, 3D point cloud of foot is reconstructed and 3D model of foot is built by mosaicking point cloud at various angles automatically. After normalization, high-order moments are compared, which is useful for the subsequent shoe last design.
