In three-dimensional imaging of structured light, the high-reflective areas of scenes to be measured will be saturated on camera imaging arrays, which affects the phase accuracy of phase-shift structured light. Therefore, an adaptive phase-shift structured light measurement method is proposed. First, several uniformly-grayscaled images are projected onto an object, the high-reflective areas and their saturation degrees are detected, and the optimal projected light intensity is determined pixel by pixel. Then, according to the object properties, the projected light intensity is reduced to realize coordinate mapping, and a group of adaptive fringes with a high dynamic range is automatically generated. Finally, the phases over the highly saturated area are fused with the phases of coordinate mapping. The experimental results reveal that the proposed method can accurately adjust the projected light intensity. Compared with the traditional method, the proposed method reduces the maximum root mean square error (RMSE) and the RMSE of the saturated areas by 99.43% and 92.48%, respectively, and it effectively improves the morphological measurement accuracy of the high-reflective areas.
