Abstract:

To improve the speediness of stereo matching algorithm,a new scanning strategy for improving algorithm is presented.During the scanning,the whole image is divided into groups of three columns from left to right,besides the first row;the scanning sequence is middle column pixel,left column pixel and right column pixel.According to the scanning strategy and the position of matching pixel in the image,the methods of reducing the execution time are given as follows:the adjacent pixels computed values of horizontal and vertical orientation are stored using less space.Experimental result shows that the proposed algorithm is the less calculation and the higher matching speed than traditional method under the same matching results and can be used in the environment requiring more real-time operation.
