摘要 针对鱼眼图像传统经度坐标校正效果不明显,提出了一种新的鱼眼图像2D校正算法,通过对每一条畸变的经线,不断重定位圆心位置,重新计算经线上点的坐标,有效地校正桶形畸变。该算法不用进行鱼眼镜头的标定以及参数的估计,也不用寻找三维空间点信息以及在各种坐标系之间进行转换。通过与传统校正算法进行对比,发现本算法能高效快捷地对鱼眼图像进行校正,而且具有较好的效果。 The 2d fisheye image correction algorithm was meant to improve the traditional longitude coordinates correction in some extent,which located in the new center of the circle for every arc constantly. The algorithm need not fisheye lens calibration, parameter estimation and three dimensional space information.Contrasted to the conventional calibration algorithm,the new algorithm could efficiently correct the fisheye image better.
