ABSOLUTE THREE-DIMENSIONAL SHAPE MEASUREMENT USING CODED FRINGE PATTERNS WITHOUT PHASE UNWRAPPING OR PROJECTOR CALIBRATION |
摘要 |
A stereo-phase-based absolute three-dimensional (3D) shape measurement method is provided that requires neither phase unwrapping nor projector calibration. This proposed method can be divided into two steps: (1) obtain a coarse disparity map from the quality map; and (2) refine the disparity map using local phase information. Experiments demonstrated that the proposed method could achieve high-quality 3D measurement even with extremely low-quality fringe patterns. The method is particular well-suited for a number of different applications including in mobile devices such as phones. |
