Research and realization of 3D digitization of static fabric based on Gray code

Combined with the Gray-encoding structured light and binocular stereo vision, the 3D digital reconstruction of the static fabric is realized in this paper. Zhang Zhengyou camera calibration method is adopted to achieve camera's stereo calibration. After choosing effective area and binarization, the images are decoded by the Gray code, thus an area matching strategy is proposed to achieve matching uniqueness, and the 3D digitalization of fabric is achieved based on binocular stereo vision. The reconstruction result demonstrates accuracy and reliability of proposed method.
