摘要
针对鱼眼镜头由于视场大而导致畸变的问题,对其拍摄的视频图像进行畸变校正。采用Chebyshev插值算法,将鱼眼镜头的非线性校正函数转换为多项式校正函数,采用流水线法快速计算多项式校正函数,并通过实例进行实验验证。结果表明:该方法能实现FPGA(field programmable gate array)平台上的实时鱼眼校正,其效果明显,实时性强。
According to the distortion of fisheye lens which caused by wide field, correction for its video should be used. The Chebyshev interpolation method for fisheye lens is taken for transforming nonlinear correcting function to polynomial correcting function, and the pipelining fast calculating method is used for calculating polynomial function, and experimental verification is carried out. The results show that this method can implement real-time correction for fisheye images based on FPGA (field programmable gate array) with its effect is obvious and its real-time performance is excellent.
