摘要： 鱼眼图像视角大，两幅图片即可拼接成全景图，但鱼眼图像存在严重变形。该文利用场景中直线的鱼眼投影曲线，使用球面透视投影约束，得到径向和切向变形参数，实现了鱼眼图像的校正。基于待拼接图像之间重叠部分亮度差最小的原理，确定了重叠区域，通过在重叠区域间的融合，实现了图像的无缝拼接。校正及拼接结果表明，该方法能得到较为满意的效果。

Abstract: Though only two fisheye images can be mosaicked into one panorama image because of its wide angle of view, it has severe distortion. Using spherical perspective projection (SPP) constraint on fisheye image’s curves of space line’s projection, radial and tangential distortion parameters are calculated, thus distortion correction of fisheye image is accomplished in the paper. According to minimum brightness difference between overlap area of images to be mosaicked, panorama images mosaics based on image fission on overlap area is discussed in the paper. Satisfactory correction and mosaics results are obtained.
