METHOD OF COMPUTER CONTROL OF TWISTED THREAD PARAMETERS FROM ITS IMAGE
Abstract
A non-hardware method for computer control of the geometric parameters of a twisted thread using a two-dimensional Fourier transform program of its computer image is proposed. First, the program calculates the diffraction pattern from the investigated image of the thread. Then, the same program builds a diffraction pattern from the image of the first pattern, which does not contain speckles in the proposed method. This makes it possible to carry out its automatic computer analysis with the output to the digital values of the calculated parameters. The effectiveness of the method is illustrated on model and industrial samples of synthetic threads.
