An Improved Fisheye Distortion Correction Algorithm

摘要:

畸变是鱼眼镜头的最大的问题，针对这一情况，提出一种利用双椭圆模型对鱼眼镜头进行畸变校正的算法，在改善鱼眼畸变的情况下，同时能够保障实时输出；对鱼眼图像进行边缘扫描和检测，采用线性拟合的方法获取鱼眼图像的光心和半径，经过双椭圆模型寻找校正前和校正后图像的映射关系，调用GPU加速处理，达到实时输出的效果，经过实验对比，针对鱼眼镜头引起的畸变问题进行校正并且能够实时输出；

Abstract:

The aberration is the biggest problem of fisheye lens, for this situation, we propose an algorithm to correct the aberration of fisheye lens by using double ellipse model, which can improve the aberration of fisheye and guarantee the real-time output at the same time; we scan and detect the edge of fisheye image, use the linear fitting method to obtain the optical center and radius of fisheye image, find the mapping relationship between the image before and after correction by double ellipse model After the experimental comparison, the aberrations caused by the fisheye lens are corrected and can be output in real time.
