A novel stereo matching algorithm via generating dense disparity map based on image segment is proposed. A robust dense disparity-space image is generated by using sliding window. The watershed algorithm is used to segment the image into several small areas. According to the distribution of dense disparity for each area, the reliability of areas is calculated. By taking the impact caused by the neighbor areas into account, the calculation result is used to generate dense disparity map. The international standard data is used to test the performance of this algorithm. Experimental results show this algorithm can achieve better matching effect.
