摘　　要：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.测量纬的针长度是必要的在为经济和改善生产率的静态的环境的编织织物。输入的图象被处理处理技术的数字图象：纸 carded 外面灰色的转变可伸缩；有过滤的媒介的然后移开的杂质；针结构的特征被使用 Fourier 变换技术提炼。更精确地获得针长度，我们应该基于处理的数字图象建立针的一个几何模型，它提供一个方法在二尺寸的空格把针长度转变成一个三尺寸的空格。这研究为没有损坏织物，测量针长度提供一个新方法。
