Fiber diameter measuring method of textile materials based on phase information

Abstract

For achieving rapid and accurate measurement of fiber diameter, so as to evaluate product performance and guide the improvement of manufacturing process, a method based on phase information for measuring fiber diameter of which the fiber images of textile materials is collected by scanning electron microscope was proposed. Firstly, the improved Kuwahara filter is used to smooth the fiber image and enhance the foreground target. Then the fiber edge was detected by phase consistency method and repaired. Then, the spatial position and direction information of each pixel on the axis of a single fiber were determined, and the boundary pixel points were found by scanning along the vertical direction of the axis. Finally, the fiber diameter is calculated according to the position of border pixel points obtained by scanning. The experimental results show that this method can accurately and effectively measure the fiber diameter. Compared with the standard manual measurement, the fiber with a relative error of less than 2% accounts for 95% of the total fiber.
