The invention discloses a three-dimensional (3D) image parallax picture obtaining method and a three-dimensional (3D) image parallax picture obtaining system. The 3D image parallax picture obtaining method comprises the steps of obtaining corresponding gray scale information through performing gray scale processing on the left image and the right image of the 3D image; performing block matching processing on the gray scale information of the left image and the right image, and obtaining a three-dimensional matrix which comprises parallax picture information; performing cost matrix processing on each line of the three-dimensional matrix, and obtaining the parallax which corresponds with each line of the cost matrix; forming the parallax picture of the 3D image according to the parallax of each line; and searching a maximum likelihood parallax picture with a least difference with a true parallax picture in all possible parallax pictures according to a Viterbi algorithm, so that higher accuracy of the obtained parallax picture is realized. An optimal solution of the parallax picture is calculated through the Viterbi algorithm, thereby greatly reducing calculation amount. Furthermore parallax picture acquisition can be realized through hardware, thereby realizing high convenience.
Description
technical field [0001] The present invention relates to the field of 3D display, in particular to a method and system for acquiring a disparity map of a 3D image. Background technique [0002] Generally speaking, a 3D image usually consists of two images, corresponding to a certain viewing angle. According to the disparity information contained in the two videos, images corresponding to new viewing angles can be generated, which is the key to naked-eye 3D TV. In existing disparity maps calculated from input images, the first step is usually block matching, and then different methods are used to optimize the block matching results to obtain more accurate results. However, the existing global algorithm for optimizing block matching results is too complex, and there are huge difficulties in implementing it with hardware, while the non-global algorithm cannot give satisfactory results. low, which brings great inconvenience. [0003] Therefore, the prior art still needs to be ...
