Study and Implementation of Distortion Correction and Mosaics of Fisheye Images
Dayu Wang · Jisuanji gongcheng · 2007
Though only two fisheye images can be mosaicked into one panorama image because of its wide angle of view,it has severe distortion.Using spherical perspective projection(SPP) constraint on fisheye image’s curves of space line’s projection,radial and tangential distortion parameters are calculated,thus distortion correction of fisheye image is accomplished in the paper.According to minimum brightness difference between overlap area of images to be mosaicked,panorama images mosaics based on image fission on overlap area is discussed in the paper.Satisfactory correction and mosaics results are obtained.
