摘　　要：针对柱面全景图拼接提出一种快速稳定的拼接算法。该方法将待拼接的二维图像的灰度值投影变换到一数轴上,选择特征明显的灰度段作为模板,通过序贯相似性检测进行匹配,并在匹配过程中能够自适应地调整阀值,后采用线性加权法对图像进行无缝拼接。采用普通相机拍摄的序列图像进行实验,实验结果证明该方法提高了拼速度,降低了图像亮度差异的影响,使结果图像自然逼真。panoramic image stitching is important in the research of image--based rendering （IBR）. In this paper, a steady and fast arithmetic is brought out to quickly create cylindrical panoramic image. This algorithm projects the 213 image to get 113 data, then selects a appropriate gray segment as the template, and completes the adjacent image stitching by employing the Sequential Similarity Detection Algorithm （SSDA） method with self--adapting threshold in template matching. Finally, by adopting linear weight method, the stitching image is more natural and lifelike. Experimental results with sequences of camera--taken images prove the efficiency of the proposed approach are given and are not sensitive to the exposure difference between consecutive images.
