为了解决因在活塞环缺陷检测的过程中，由于相机与活塞环之间存在相对运动，使图像产生运动模糊，对后面的缺陷特征提取、目标识别和图像分析产生的不良影响，以运动模糊图像的点扩展函数估计为中心，推导和计算出图像模糊的模糊角度以及模糊长度，然后应用维纳滤波的方法，得到复原后的质量得到改善的图像。同时通过实验的方法，测试了图像复原的结果，得到经过预处理后质量较高的图片。

Abtsr act:There is relative motion between the camera and the piston ring in the process of defect detection for piston ring .This makes the image produce motion blur inevitably , affects the defect feature extraction and target recognition and image analysis .Taking the estimation of point spread function of the motion blurred images , it derives and calculates the blur angle and blur length of the blurred images , applies the method of Wiener filtering to improve the image quality after the restoration .Based on the experimental methods , it tests the effect of image restoration, obtains the pretreatment of high quality .
