基于数字图像处理方法的激光损伤识别

Laser damage identification based on digital image processing

针对传统激光损伤识别方法工作复杂、识别精度低的缺陷,提出基于数字图像处理方法的激光损伤识别法。使用点阵矩阵采集物体结构信息,更新信息进行时序并将其存储为数字图像,通过在图像上建立数字图像坐标系,按照时序进行图像信息识别,提取图像损伤区域,利用卷积函数对图像损伤区域进行去噪处理,采用小波分解方法在对图像损伤区域进行二次去噪,同时计算出物体结构的损伤方位。结果表明,该方法具有很强的损伤识别能力及实用性。

In order to overcome the defects of traditional laser damage identification methods,such as complex operation and low precision,a new method based on digital image processing is proposed.Use lattice matrix to acquire,update,and time the objects＇ structure information,and then store them as digital images.Extract the image damage area through the establishment of digital image coordinates on the image and the image information identification by timing.Denoise the damage area by using convolution function,use wavelet decomposition method for secondary denoising and calculate the damage orientation of the damage simultaneously.The results show that the method has a strong ability of damage identification and practicability.
