| 摘 要： | 提出了基于区域的立体匹配算法,实现从彩色立体图像对中提取深度信息.其中利用平滑函数求取全局错误能量最小化获得的视差图更为可靠,但是计算时间也较长；而采用线性生长算法获得的视差图则计算时间短,但可靠性差.结果是利用滤波去掉了不可靠的视差估计,可以提高视差图的可靠度,还对算法生成的结果进行了比较.

| Abstract: | In the paper,region based stereo matching algorithms are developed for extracting depth information from two color stereo image pair.It shows that global error energy minimization by smoothing functions method is more reliable but more time consuming,and that line growing method is more convenient for the sequential computing architectures because of promising higher speed.Filtering unreliable disparity estimation can increase reliability of disparity map.Finally,a comparison of the algorithms is presented. |
