摘　　要：通过对SIFT特征提取算法进行改进,实现对多路高清图像重合区域提取特征点,采用基于RANSAC方法实现图像重叠区特征的精确配准,通过反向投影变换模型和相机的内参和相机间的外参生成图像复合变换矩阵,对每路高清图像的实现变换、投影及广角拼接。To extract feature points from overlapped regions of multiple HD images based on the improved SIFT feature extraction algorithm,we get the accurate registration of image overlapping area based on Random Sample Consensus method.We generate the image composite transformation matrix through the back projection transformation model,the camera’s internal references and the camera’s external parameters.Then the transformation,projection and wide-angle stitching of each HD image are realized.

关 键 词：全景拼接 高清图像 SIFT 投影变换
