摘要
子午线轮胎的缺陷检测方法比较多,频谱分析法是基于频域的图像分析方法,其主要功能是获取图像在频域中的纹理特征。傅里叶变换能够将时域的信号分解为频域各频率分量下之和,即分解为各个频率下的谱。然后通过对得到的频谱进行图像处理,判断轮胎有无缺陷。实验证明使用基于傅里叶变换的频谱分析法进行子午线轮胎缺陷检测可以大幅降低工作量,提高轮胎检测效率。
There are many ways to have the quality inspection of the meridian tires, spectrum analysis is the Image analysis method in frequency domain, the primary function is to obtain the textural features of images in frequency domain. Fourier transform can change signals from time domain to frequency domain and get each frequency component, that is decomposed signals into different frequency spectrum. Then we can have image processing and evaluate whether the tires have defects or not. The experimental result shows that the spectral analysis based on Fourier transform of the tire X-ray detection can greatly reduce the workload, and improve the efficiency of the tire X-ray detection.
