| 摘 要： | 为了修正广角镜头的桶形畸变,提出了一种基于多项式的修正方法,该方法首先用模板对广角镜头进行相对标定,然后用四次多项式拟合桶形畸变规律,最后根据拟合多项式对变形图像进行恢复。对于固定焦距视觉系统,在不考虑视觉系统具体参数的情况下,新的方法能够快速有效地对广角镜头桶形畸变进行修正。该方法在实验中表现出了良好的效果。

| Abstract: | In order to correct the barrel distortion due to wide-angle lenses,a new method based on a polynomial is proposed.The wide-angle lens is relatively calibrated by a template,and then the quartic polynomial is used to fit the rules of barrel distortion.The distortion image is restored according to the fitting polynomial.For the vision system with fixed focal length,the method can correct the barrel distortion rapidly and efficiently without taking into account the parameters of the vision system.The new method produces good effect in experiment. |
