Improved segment-based 3D surface stereo matching algorithm
Ka He · Journal of Jilin University · 2014
In the traditional segment-based stereo matching approaches,local matching tends to get high mismatching rate;mover over,the plane fitting method has its limitation.In order to obtain high accuracy of disparity map,the initial disparity map is obtained by combining the improved local matching method with global one.Simultaneously,the surface model is utilized to fit each segmented region,and a decision rule of regions merging is proposed.The simulation results show that the proposed algorithm can obtain higher accuracy and more smooth disparity map between texture regions.Besides that,superior results are realized in both low-texture and texture-occluded regions.
