Abstract

The invention discloses a stereo matching method and a device thereof. The stereo matching methods comprises the steps of detecting whether scene change exists or not between a current frame and a previous frame, updating a matching cost aggregate value of each pixel in the disparity space image of the current frame by using the similarity between the current frame and the disparity map of the previous frame when the scene change does not exist between the current frame and the previous frame, and obtaining the disparity map of the current frame by using the disparity space image of the current frame after updating. By using the stereo matching method and the device, the obtained jitter in the disparity map can be eliminated in the condition that the time consistency is not considered.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a stereo matching method and device. Background technique [0002] Stereo matching is to take two or more images of a certain scene, estimate the three-dimensional (3D) model of the scene by accurately finding the matching pixels between the images, and convert the two-dimensional (2D) positions of the matching pixels between these images For 3D depth processing. In simple imaging configurations (e.g., two eyes or two cameras looking straight ahead), the disparity between the two eyes or two cameras is related to the distance between the two eyes or two cameras and the observed object. Inversely proportional to the distance of , that is, the stereoscopic depth of the observed object in the captured image. Therefore, disparity maps are often used to describe the stereoscopic depth of pixels in captured images. [0003] In traditional stereo matching methods, usually one ...
