摘　　要：针对针织物结构具有一定空间周期性的特点,在对针织物图像预处理之后,利用傅里叶变换技术来提取横纵密的空间频率信息,测量针织物的横纵密。实验结果表明,该方法可以自动、快速、准确地实现横纵密测试的目的。Since a knitted fabric consists of regular repeating units, after preprocessing its original image, applying the FFT to the image and getting frequency character of its density, the density is measured. The experimental results show that it can measure the knitted fabric's density automatically, quickly and correctly.
