摘　　要：基于等距离匹配思想,提出了一种快速的全景图像生成算法。对于相邻两幅待匹配图像,设定相同大小的比较区域,采取随机取点的方式,从两幅图像中心垂线开始向重叠方向同步长移动并计算对应点的颜色差值并累加,若达到某一设定阈值,则停止计算。计算次数最多的比较区域中心位置即为最佳匹配位置。本算法可以尽早排除非匹配位置,减少计算时间,提高全景图像生成的速度。Based on the equidistant matching,a fast algorithm for cylindrical panoramic image mosaic is proposed in this paper.First,choose the regions of the same size for comparison in two overlapping images.Then,move the regions to the edges in overlapping direction from the perpendicular centerlines of the images with the same step length respectively.Next,calculate the color differences of corresponding sampling pixelsn at random and accumulate the times.Do not stop the calculating until the accumulated value reaches the threshold.The position with the most calculating time is the best mosaic location.The algorithm can exclude non-matching location as soon as possible.and so cut down the matching time.
