The Fast Correction Algorithm Research Of Image Geometric Distortion In The Image Tracking.

Abstract: This paper first briefly introduces the image of the principles of geometric distortions. And in the basis of analyzing polynomial algorithm on the coordinate conversion, it approaches a distortion algorithm non-uniform by region. The fixed focus image is established to the corresponding model and non-uniform divided to rectangular areas which are within a polynomial in a high order polynomial. By comparing the correction effect and devotion of time of the correction method between one order region and third order polynomial, the validity of the proposed method by the article can be verified.
