Abstract:
1. An image processing method for projection transforming of an original image into a transformed image, the transformed image correcting distortion of the original image, the method comprising: partitioning a whole area of the transformed image to be obtained by a projection transformation of the original image into a plurality of regions, wherein none of the plurality of regions is intersected by either a vertical axis or a horizontal axis, the vertical and horizontal axes extending in a plane containing the transformed image and passing through an origin at a center of the whole area; determining, for each region of the plurality of regions defined in the whole area of the transformed image, a corresponding region in the original image that corresponds to each of the plurality of regions defined in the whole area of the transformed image; and performing the projection transformation for each of the corresponding regions defined in the original image to obtain the transformed image, wherein the partitioning step includes: the determining step determines, based on the second regions, the corresponding regions in the original image.
