There are two shortcomings in the existing multi-perspective mosaic algorithms:numerous viewpoints are needed to extract e-nough strips for stitching,and each viewpoint is required to simulate facing towards dominant scene plane or each viewpoint allows rota-ting a small angle for minimal strip distortion,which limit the application of multi-perspective mosaicing to large extent.In this paper, present a new multi-perspective mosaic algorithm based on sparse and rotatable viewpoint.This algorithm adopts the strategy of two steps,which are virtual transformation and synchronized correction and registration.The first strategy aims to remove the different per-spective deformations when the cameras do not facing towards the scene,while the second one updates the changing overlapping area be-tween neighboring views when the cameras rotate.Experimental results show the proposed method is feasible.%目前的多透视拼接算法存在两点局限：需要大量源视点以保证足够多的拼接切片可以提取；视点方向应与水平运动方向垂直以模拟与场景面的正交投影或视点旋转角度较小以实现最小扭曲拼接。这两点很大程度上限制了多视点拼接的应用。为此，提出一个基于稀疏可旋转视点的多透视拼接算法。该算法采取两步走的策略，即虚拟变换和同步校正与配准。解决相邻视点成像时因与场景面不垂直而产生的不同程度透视变形以及视点因旋转角度变化而产生的重叠区域变化问题，实现稀疏可旋转视点图像拼接。实验结果表明该算法是有效的。
