| 摘 要： | 提出了一种柱面图像拼接方法,首先利用扩展相位相关算法获取变换矩阵,将其经过Levenberg-Marquart（LM）算法优化之后获取理想8参数模型,其次利用8参数模型进行同心圆焦距的估计,获取柱面拼接图像的半径,最后对投影后的柱面图像再利用扩展相位相关算法、加权融合算法进行拼接,实验验证了这种方法的有效性。 |
| 关 键 词： | 扩展相位相关 Levenberg-Marquart算法 焦距估计 图像拼接 |

| Abstract: | A new mosaic method of cylindrical images was proposed. Firstly, the transformation matrix was gained by the extention of phase correlation. After the optimazation of Levenberg-Marquart algorithm, the ideal 8 parameter transformaion matrix was gained. Then, the cylindrical radius was calculated by the same circle focal length. Finally, the extention of phase correlation and weighted image blending were used to the cylindrical image mosaic. The experiment demonstrates that the method is effective. |
| Keywords: | extention of phase correlation Levenberg-Marquart algorithm estimation of focal length image mosaic |
