Abstract

Fisheye lens had the characteristics of shorter focus and large field,but fisheye images were distorted.Current fisheye distortion correction algorithms had some problem,such as,taking point from the scene was approximate,fitting process was complex,the computational cost was large and the real-time character could not be guaranteed.In this paper, firstly,obtain the formula according to fisheye lens imaging principle.Secondly,get a correction curve from the special points' relationship between the image captured by specific fisheye lens and calibration image. Finally,use the curve to obtain the pixel map table between the fisheye image and the target image. Thus realize the fisheye image distortion's correction. The results show that it is a real-time,fast,accurate fisheye image correction method.
