Dual-Wavelength Fringe Projection Correction Algorithm Based on Color Segmentation
Aiming at three-dimensional topography measurement based on structured light projection, a dual-wavelength fringe projection correction algorithm based on color segmentation is proposed in this paper. A color fringe image is added on the basis of the wavelength-selective dual-fringe projection phase unwrapping algorithm, and the fringe image is divided into different fringe regions by color. Phase unwrapping is performed on the phase map by means of a look-up table in different fringe regions. The experimental results show that the algorithm has the advantages of wide measurement range, small amount of calculation, high precision and fast speed. The experimental results show that the algorithm has the advantages of wide measurement range, small amount of calculation, high precision and fast speed, and can effectively solve the problem of repeated lookup tables when the selected wavelength is short.
