问：摄氏温度单位“℃”的中文符号是什么？答：按规则，单位名称的简称即为该单位的中文符号，如压强单位Pa的中文名称为帕斯卡，其简称“帕”即为Pa的中文符号。
There are still some common issues existing in the region stereo matching algorithm for the selection of matching windows and region matching in disparity discontinuity and weak texture. In order to solve these problems, this paper proposes a stereo matching algorithm based on the combination of adaptive window and semi global algorithm. Firstly, the initial matching cost are calculated based on adaptive window matching algorithm. Then, Semi-global stereo matching algorithm is used, in which there is a constraint by disparity gradients between adjacent pixels,to obtain the initial disparity map. Finally, left-right consistency check is employed to eliminate the errors taken place in occluded regions, and obtained the dense disparity map. The authors take adaptive windows and semi-global stereo matching algorithm for different images to correct mismatching points in the disparity discontinuities and weak texture regions. Experimental results show that the proposed algorithm can reduce the error matching rate effectively, and improve the matching accuracy in the disparity discontinuities, weak texture and occlusion region.
