基于Radon变换的电气连接器图像倾斜校正

Image Tilt Correction of Electrical Connector Based on Radon Transform

电气连接器在拍摄的过程中不可避免会产生图像倾斜现象,倾斜的图像不利于图像特征分割,为解决图像倾斜问题,提出基于Radon变换的图像倾斜校正方法。该方法先利用边缘检测中的Sobel边缘检测算子检测图像边缘,再利用Radon变换检测倾斜图像的倾斜角,最后根据检测到的倾斜角利用双线性插值对图像进行旋转,最终完成倾斜图像的校正。经试验验证该算法处理速度快、适应性好,对噪声与污染不敏感。

Electrical connector in the process of shooting will inevitably produce image tilt,the inclined image is not conducive to image feature segmentation,image tilt correction method based on Radon transform is proposed to solve the problem of image tilt. Firstly,edge detection operator is used to detect the edge of image by Sobel edge detection operator. Secondly,Radon transform is used to detect the tilt angle of edge image. Finally, the bilinear interpolation method is used to rotate the image. The experimental results show that the algorithm is fast and adaptive,and it is not sensitive to noise and pollution.
