Abstract EN
There is always a great challenge for the structured light technique that it is difficult to deal with the surface with large reflectivity variations or specular reflection.
This paper proposes a flexible and adaptive digital fringe projection method based on image fusion and interpolated prediction search algorithm.
The multiple mask images are fused to obtain the required saturation threshold, and the interpolated prediction search algorithm is used to calculate the optimal projection gray-level intensity.
Then, the projection intensity is reduced to achieve coordinate matching in the unsaturated condition, and the adaptive digital fringes with the optimal projection intensity are subsequently projected for phase calculation by using the heterodyne multifrequency phase-shifted method.
The experiments demonstrate that the proposed method is effective for measuring the high-reflective surface and unwrapping the phase in the local overexposure region completely.
Compared with the traditional structured light measurement methods, our method can decrease the number of projected and captured images with higher modulation and better contrast.
In addition, the measurement process only needs two prior steps and avoids hardware complexity, which is more convenient to apply to the industry.
