摘　　要：现有鱼眼镜头生成全景图像方法中,对不同镜头采用相同的镜头参数,只优化方向变化,该条件并不能满足镜头参数不同的情况。为此,提出一种新的方法,即在匹配点优化镜头参数的过程中,对每个镜头使用独立参数,单独优化每个镜头的参数。再使用图割法计算相邻图像最佳拼接缝隙并使用多分辨率融合。实验结果表明,相比于统一参数的相机参数优化,独立参数更能精确地表示每个镜头的真实情况,并且获得更好的拼接结果。In the existing method for generating panoramic images with a fisheye lens,the same lens parameters are used for different lenses,and only the direction change is optimized.This condition cannot meet the situation of different lens parameters.To this end,a new method is pro⁃posed in the process of optimizing the lens parameters at the matching point by using independent parameters for each lens and optimizing the parameters of each lens individually.Then use the graph cut method to calculate the optimal stitching gap of adjacent images and use multi-resolution fusion.The experimental results show that compared with the optimization of camera parameters with uniform parameters,the independent parameters can more accurately represent the real situation of each lens and obtain better stitching results.
