The invention provides a quick semi-global dense matching method and device. The quick semi-global dense matching method includes the steps that a base image and a matching image which are to be matched and have a epipolar line relation are obtained; matching calculation is carried out on the base image and the matching image according to a dense matching algorithm and the epipolar line relation; an obtained base image disparity map and an obtained matching image disparity map are denoised and refined; consistency detection is conducted on the base image disparity map and the matching image disparity map obtained through denoising and refining processing to obtain a matching base image disparity map. According to the method, the base image and the matching image are calculated according to the dense matching algorithm and the epipolar line relation, the two obtained disparity maps are denoised and refined, noise in the disparity maps is filtered out, consistency between the object boundary in the disparity ma
