Abstract:
1. An image generating method for image rectification, comprising the steps of: dividing equally an arc curve of a spherical screen, which corresponds to a radian of 90°, into a plurality of curved surface segments with the same area, each of the curved surface segments having a radian of 90°; equally dividing each of the curved surface segments into n parts to obtain a distribution diagram with n equisection points, wherein n is a natural number; disposing a light source on the distribution diagram with the n equisection points; equally dividing, according to a planar image that needs to be displayed, a straight line of the planar image corresponding to the arc curve into a plurality of segments, the number of the segments of the straight line being equal to the number of the curved surface segments of the arc curve; assigning an image parameter of a first point in the planar image to a third point in the planar image; connecting a sphere center with a second point of a to-be-displayed image on the arc curve that corresponds to the first point, a point falling in the planar image being the third point; and displaying the rectified planar image on the arc curve of the spherical screen.
