Abstract

The present invention is to provide a method for enabling an electronic device to read at least two images taken from different positions by a digital camera mounted with a fisheye lens; acquire internal and external parameters of the fisheye lens corresponding to the different positions as well as the vignetting coefficient for eliminating the vignetting on the images; perform exposure compensation and color calibration on the images for letting them have consistent brightness and hues; project the images onto a spherical surface and spread out the spherical surface to form a two-dimensional spread-out picture based on the parameters; register the overlapped images projected on the two-dimensional spread-out picture and adjust the offset of corresponding pixels thereof, register and adjust the brightness and hues of the overlapped images into consistency; and fuse overlapped images together to produce a 360-degree spherical panorama without having any noticeable stitching seam between the images.
