Because the point spread function (PSF) of the panoramic image is spatially vari ant,an algorithm using Radon transform to estimate the PSF of the localized panoramic image is proposed.We first analyze the panoramic imaging system and the relationship between the Radon transform of the PSF and the blurred lines in the image.Then the effective sampling method is used to get isolated sampling edges.Finally the PSF is restor ed by using the sample information and the image is deblurred by the Lucy-Richardson algorithm.Meanwhile,the iterative optimization algorithm is used to overcome the problem of the less sampling edges,which leads to inaccurate estima tion of the PSF.The experiments show that the algorithm can effectively estimate the PSFs of the different localized panoramic images and i t also can be used in engineering practice.
