1. An image processing method, comprising: (a) capturing a plurality of images corresponding to the surroundings of an object using a plurality of image capturing modules to generate a two-dimension planar image; (b) providing a three-dimension projected curved surface, defining a plurality of first grids on the three-dimension projected curved surface and a plurality of second grids on the two-dimension planar image, wherein each of the first grids corresponds to each of the second grids; (c) transforming the first grids on the three-dimension projected curved surface and the second grids on the two-dimension planar image into a plurality of first redrawn grids and second redrawn grids respectively based on the angles formed between the normal vector of the two-dimension planar image and the normal vector of each first grid, wherein each first redrawn grid corresponds to each second redrawn grid; and (d) projecting an image data of the second redrawn grids onto the first redrawn grids correspondingly to generate a three-dimension image.
