Abstract: On the premise of image binary, image contour is obtained by means of an improved algorithm based on region growing, image correction can be completed. It can overcome the shortage that massive black pixels appear in the fisheye image circular outline area and make the statistical algorithm fail. Simulation results show that the proposed algorithm has advantage of high precision and high efficiency, satisfactory results are obtained.

Key words: fisheye image, region growing, contour extraction, nonlinear least square fitting
