一种柱面全景图像自动拼接算法

提出了一种基于特征块匹配的柱面全景图像拼接算法.首先将360度环绕拍摄的序列图像投影到柱面坐标系下;然后以一幅图像为基准图像,选择基准图像中边缘信息丰富的块作为基准块,利用特征块匹配法在待配准图像中找出与基准块匹配的配准块,进而实现两幅图像的配准;再根据配准结果计算出图像间的变换参数;最后采用平滑因子对两幅图像的重叠区域进行图像无缝拼接.实验证明,算法可以快速自动地生成柱面全景图像,具有良好的鲁棒性.

A Cylindrical Panoramic Image Mosaics Algorithm Based on Block-Matching

In this paper,an efficient cylindrical panoramic image mosaic technique was proposed.Firstly,the 360 degrees of circle panned image sequences are projected to cylindrical coordinate separately.Then taking an image as base image,and the block with most edge information is selected as the reference module,then block-matching method is used to register the neighboring images.Then the transform parameters can be calculated by the registration results.Finally,smooth factors are used to merge the overlapped image...
