  • Patent number: 9436973
    Abstract: In an image processing for correcting a distorted image obtained by photography by use of a super-wide angle optical system such as a fisheye lens or an omnidirectional mirror, to obtain an image of a perspective projection method, a composite index (Rn) combining a height on the projection sphere with a distance from the optical axis is computed (301), and a distance (Rf) from an origin in the distorted image is computed (302), using the composite index (Rn). Further, two-dimensional coordinates (p, q) in the distorted image are computed (303), using the distance (Rf) from the origin, and a pixel value in an output image is determined using a pixel at a position in the distorted image specified by the two-dimensional coordinates, or a pixel or pixels neighboring the specified position. It is possible to perform the projection from the projection sphere to the image plane, that is, the computation of the coordinates on the coordinate plane, while restricting the amount of computation.
