Abstract
To resolve the problem of low stereo matching accuracy of current phase stereo matching algorithm,a matching method based on the combination of Gray code and phase-shift was put forward.The method used Ostu algorithm to gain the optimal segmentation threshold,and the accuracy segmentation of the Gray code image was carried out.The Gaussian filter was presented to filter the sine grating image,and the high precision phase could be obtained by combining with the Gray code.The object measuring experiment results indicated that this method can improve the matching accuracy and obtain the better measuring result.
