Abstract：Aiming at the mismatching problem in low texture areas and the well-known streaking effect of dynamic programming, an improved algorithm based on binocular stereo matching technology is proposed to generate three-dimensional reconstruction model for low texture images. Firstly, matching cost is computed based on the distinctiveness of pixels and the similarity among them. Secondly, an adaptive polygon-based support window is adopted in the matching cost aggregation, and a simple tree structure dynamic programming is introduced to guide the pixel to pixel matching. Finally, a simple and efficient method is presented to refine the mismatching pixels detected according to the left-right consistency constraint. To testify the applicability of the proposed algorithm, it is applied to low texture gray images captured in the real situation, and the experimental results show that smooth and vivid 3D points cloud models are generated.
