Abstract
This paper proposes a method based on three viewpoints and phase assistance. This method combines the projector as a reverse camera and a binocular measurement system to form a three-viewpoint system. The three-step phase shift method is used to obtain the wrapped phase image pair of the left and right cameras and the projector. Then, the polar line between the three viewpoints is used. The constraint relationship eliminates the matching ambiguity caused by the wrapping phase and realizes the stereo matching. In addition, a matching algorithm that assigns weights to the phase template is proposed, and the initial matching point is determined by using the phase information and the matching template. Finally, for some special matching points that are not located on the pixel point, the matching point corresponding to the obtained minimum value is determined as the final matching point using phase-grayscale double constraint. The experimental results show that the method can achieve high-precision measurement of objects, and has good noise immunity.
