Stereo matching by means of digital speckle

Stereovision is one of the most widely used techniques as a powerful passive optical sensing method.The stereo matching is a key point of such technique.However,the conventional matching method is rather inefficient to measure continuous and characterless surface,which may lead to severe matching mistakes.So an aided digital speckle projection is proposed in such environment.The dense disparity map is achieved using the mean normalized cross correlation in our experiment.
