为解决传统的图像镶嵌方法在出现局部运动目标的情况下产生的重影现象，提出一种改进的针对运动目标重影去除的方法。对于N帧图像，算法首先通过SIFT特征点聚类和运动特征点剔除方法过滤这些图像特征点，在消除参数累积误差之后，通过三帧差法分离出背景并使用无缝融合方法完成前N-1帧图像的背景融合；然后把最后一帧与前N-1帧的已镶嵌图像进行匹配和融合，得到最后的全景镶嵌图像。实验结果表明：该算法能有效解决全景图像镶嵌中运动目标的重影问题，并保留当前最后一帧图像的运动信息。

In order to solve the problem of significant ghost phenomenon produced in image mosaic results caused by moving obj ects occur in image sequence,an improved method which is mainly used to eliminating of ghosting is proposed.With this method,after SIFT feature points cluste-ring algorithm is employed,the geometric similarity relation between matching pairs is used to e-liminate feature points on moving obj ect,thus accurate feature point matching pairs filtered out. After eliminating cumulative errors,use three frames difference method to extract the back-ground of the previous N-1 frames and fuse them together,then match the last frame with it to produce the final panoramic mosaic image.The result shows that the improved method can effi-ciently remove the ghost occur in the panoramic images and keep the moving information of the last frame.
