| 摘要 |
The present invention relates to a processing method that emphasizes neighboring information around a disparity surface included in a source disparity space image by means of processing that emphasizes similarity at true matching points using inherent geometric information, that is, coherence and symmetry. The method of processing the disparity space image includes capturing stereo images satisfying epipolar geometry constraints using at least two cameras having parallax, generating pixels of a 3D disparity space image based on the captured images, reducing dispersion of luminance distribution of the disparity space image while keeping information included in the disparity space image, generating a symmetry-enhanced disparity space image by performing processing for emphasizing similarities of pixels arranged at reflective symmetric locations along a disparity-changing direction in the disparity space image, and extracting a disparity surface by connecting at least three matching points in the symmetry-enhanced disparity space image.
