摘　　要：针对动态场景拼接中存在较大曝光差异以及运动物体这两个问题,提出了一种动态场景拼接算法。该算法分为3个步骤,实现源图像之间的配准、最佳缝合线、利用泊松融合实现拼接。实验结果表明,文中算法可以较好地避开运动物体,形成拼接图,以免形成鬼影。In view of the simultaneous question of（A） Large exposure difference and（B） Moving Objects in dynamic scene stitching,this paper proposes a technique which overcomes these limitations.This technique has three steps.The first step resolves the match of input images.The second step researches the best seam while the third step stitches the pictures with the help of Poisson＇s equation.Experimental result shows that this algorithm can avoid the dynamic elements and prevent ghosting.
