双目视觉中立体匹配模板自适应选取研究

Research on Selecting Method of Stereo Matching Template in Binocular Vision System

为解决立体匹配过程中匹配模板选取问题,该文对匹配模板的自适应选取方法进行研究,并提出三种选取的方法,第一、二种方法根据像素所处位置的匹配模板越界情况,对图像进行不同的区域划分并选取相应模板,第三种方法在匹配模板越界的情况下,以匹配点的未越界的相关点作为匹配模板,不同点的匹配模板大小是可变的。将不考虑越界的匹配方法及三种方法获得的视差图及运行时间进行比较,实验结果表明,该文提出三种方法均获得了图像的更多有效的视差信息。

To solve the problem of selecting template during stereo matching, three methods of template adaptive selecting was presented. In the first and second methods, According to the position of matching pixel in the image, which are cross-border situation of matching template, the image is divided into different region and matching window is selected, In the third method ,in case of matching template are cross-border, the related points is selecting, different points of template matching size is variable.The method of Regardless of cross-border and three mehods are compared, Experimental result shows that three methods can obtain good parallax information.
