Cylindrical Panoramic Image Mosaicing Based on Phase Correlation Method

针对基于图像绘制技术中柱面全景图拼接问题 ,该文研究了利用相位相关法 ,通过对图像作快速傅立叶变换 ,利用频域中的相位信息来实现图像的拼接 ,实验表明该方法大大提高了拼接速度 ,并且能够有效地克服图像间光照变化和相机镜头造成的几何畸变对拼接的影响 。

In this paper,phase correlation method is used to complete cylindrical panoramic image mosaicing in image based rendering technique.With Fast Fourier Transform of images,the phase information in frequency domain is used to realize image mosaicing.The experiments show that the method obviously improves the speed of image mosacing,and effectively overcome the effect of varying illumination between the images and lens distorition of cameras on image mosaicing.It is a rapid and available method of cylindrical ...
