Measuring Structural Parameters of Knitted Fabrics by Digital Image Processing Techniques

In the knitting industry the measurements of the stitchdensity and the stitch length are usually done manuallywhich may lead to fatigue of the eyes,subjective ideasbrought into the test results and low precision.The mostcommon method of measuring stitchlengthin static state isby raveling the stitch.Damage tothe fabricis unavoidable.Therefore it is necessary to find a scientific and feasibletrial balloon.Digital Image Processing Techniques are nowbroadly applied in many scientific aspects inc…     

A New Method for Measuring the Stitch Length of Weft Knitted Fabric in a Static Environment

It is essential to measure the stitch length of weft knitted fabric in a static environment for economy and improving productivity. The image inputted was dealt with the digital image processing techniques： the paper carried out the transformation of grey scale; then removed impurities with filtering; the characteristic of the stitch structure was abstracted by using the Fourier transform technique. To obtain the stitch length more accurately, we should establish ageometric medal of the stitch lined on the digital image processing, which provides a way to transform the stitch length in the two-dimenslon space into a three-dimension space. This study provides a new methed for measuring the stitch length without damaging the fabric.     

二维傅里叶变换在针织物的密度测量中的应用

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。
