Research of Virtual Navigation Based on Fisheye Image

A new fisheye image edge extraction algorithm was proposed based on its round valid area;the overlap area of images to be mosaicked was determinated according to the minimum brightness difference in this area,and thus the fisheye images mosaics were accomplished after images fusion;finally,the virtual navigation was accomplished through color information extraction form fisheye images directly.Results show that ideas can improve real time requirement of the virtual navigation greatly and the good effect can be gained.
