一种全景图快速生成算法及其实现

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维数轴上，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，最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接速度，降低了图像亮度差异的影响，使结果图像自然逼真。

An Algorithm for Fast Creating Panoramic Image and Its Implementation

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 2D image to get 1D 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.
