摘要
针对数字图像梯形畸变的问题,提出一种改进的数字图像梯形畸变校正方法,该方法利用水平梯度算子进行边缘检测,接着利用Radon变换提取直线轮廓,最后用畸变校正矩阵对图像校正。实验表明,该方法能够快速有效地进行校正,具有较强的鲁棒性。
According to the problems of trapezoidal distortion in digital images,an improved method of trapezoidal distortion correction is proposed in this paper.First use the horizontal gradient to detect edges,and then use Radon transform to pick up the outline.Finally correct the distortion image with the correction matrix.Experimental results show that it can correct the images fast and effective,it is also shown that the approach is robust.
