The invention relates to a method and system for binocular fish-eye image splicing and unfolding correction. The method for binocular fish-eye image splicing and unfolding correction includes the steps: utilizing a binocular fish-eye camera to obtain an original binocular fish-eye image, and extracting the left and right two effective circular imaging areas from the original binocular fish-eye image; extracting the characteristic points of the overlapped part in the two effective areas, and matching the characteristic points in pairs; respectively mapping the two effective area images to obtain two space coordinate unit spherical surface images, performing matrix singular value decomposition on the three dimensional space spherical surface, obtaining the rotation relation, that is, the rotation matrix, between the two images through calculation, and correcting one of the space coordinate unit spherical surface images through the rotation matrix; and finally respectively mapping the twospace coordinate unit spherical surface images to obtain two panoramic coordinate images, and splicing the two panoramic coordinate images into a complete 360 DEG panoramic image. The method and system for binocular fish-eye image splicing and unfolding correction can solve the problem that the fish-eye imaging sensors are not in parallel during the assembling process, thus causing errors, and have the advantages of being good in the splicing effect after correction, being high in processing timeliness, and being easy to implement.
