Problems solved by technology

[0006] Segmentation-based algorithms largely solve the problem of pixel-based algorithms: the processing time is too long
However, segmentation-based algorithms bring a new problem: there are severely wrong disparity values ​​in some regions
[0007] It can be seen that the typical stereo matching algorithm based on segmentation is somewhat blind and relies too much on the initial disparity image, and the obtained disparity map may not be accurate enough

Embodiment Construction

[0039] Reference will now be made in detail to specific embodiments of the invention, examples of which are illustrated in the accompanying drawings. While the invention will be described in conjunction with specific embodiments, it will be understood that it is not intended to limit the invention to the specific embodiments disclosed. It should be noted that the method steps described herein can be realized by any functional blocks or functional arrangements, and any functional blocks or functional arrangements can be realized as physical entities or logical entities, or a combination of both.

[0040] As mentioned above, typical segmentation-based methods are blind and rely too much on the initial disparity image, however, if the scene is known and introduced into the disparity calculation process, the configuration of the disparity value will be more accurate. According to the present invention, by classifying the regional blocks obtained by dividing the reference image, di...

Abstract

The invention discloses a method and system for allocating parallax values. In one embodiment, the method can include the steps of obtaining a reference image; dividing the obtained reference image into a plurality of areas; classifying the multiple areas obtained through division; allocating the parallax values to pixels in each area based on classifying results. According to the method and system for allocating the parallax values, the parallax values can be more accurately allocated, and accurate and dense parallax images are obtained.

Description

technical field [0001] The present invention relates to the field of image processing, and more particularly to a method and system for configuring disparity values. Background technique [0002] In recent years, stereo vision technology has gained widespread attention. The basic principle of stereo vision is to combine the information of two (binocular) or more viewpoints to obtain images of the same object under different perspectives, and use the principle of triangulation to calculate the position deviation between the pixels of the image to obtain the object stereo information. The stereo vision includes processing such as image acquisition, camera calibration, feature extraction, stereo matching, depth and interpolation. Among them, the disparity information (depth information) obtained through stereo matching technology can be used to estimate the relative distance between the camera and the object. These disparity information can be applied to many occasions, such ...
