The invention provides a three-dimensional image matching method and equipment thereof. The equipment comprises a cost computing unit, a cost gathering unit and a parallax determination unit, wherein the cost computing unit is used for computing matching cost between the pixel of a reference image and the pixel of a target image, the cost computing unit is used for respectively computing a nonparametric statistics cost function and a color average absolution difference function between the pixel of the reference image and the pixel of the target image, and carrying out linear combination of the nonparametric statistics cost function and the color average absolution difference function, and taking the combination result as the matching cost between the pixel of the reference image and the pixel of the target image; the cost gathering unit is used for gathering the matching cost between the pixel of the reference image and the pixel of the target image, computed by the cost computing unit; the parallax determining unit is used for determining the parallax from the pixel of the reference image to the target image on the basis of the result of the gathering of the cost gathering unit to the cost matching unit so as to realize three-dimensional image matching.
Description
technical field [0001] The present invention relates to a method and device for image processing, in particular to a method and device for stereoscopic image matching between a reference image and a target image. Background technique [0002] Stereo image matching is an important technical topic in the field of computer vision. The disparity map is obtained during the process of implementing stereo image matching between a reference image (for example, left image) and a target image (for example, right image). Visual disparity) refers to the position vector between different projections of the same spatial point in the left image and right image seen by the binocular vision in binocular vision. In practice, since the perception of depth by the human eye depends on the parallax in the horizontal direction, the parallax may only refer to the horizontal component of the position vector. [0003] As mentioned above, parallax is the basis for generating depth perception. Therefo...
