This paper presents a novel stereo-phase-based absolute three-dimensional (3D) shape measurement 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 wrapped phase. Fringe patterns are modified to encode the quality map for efficient and accurate stereo matching. Experiments demonstrated that the proposed method could achieve high-quality 3D measurement even with extremely low-quality fringe patterns.
本文提出了一种基于立体相位的新型绝对三维（3D）形状测量方法，该方法既不需要相位展开，也不需要投影仪校准。该方法可分为两个步骤：（1）从质量图中获取粗略的视差图；（2）使用包裹相位对视差图进行细化。对条纹图案进行修改以编码质量图，从而实现高效准确的立体匹配。实验表明，即使使用质量极低的条纹图案，该方法也能实现高质量的3D测量。
