wherein H is the coincidence ratio of the first path image and the second path image; p is the length parameter of the pixel of the second path image; q is the width parameter of the pixels of the second path image; r is R s,t The value of the pixel point of the s-th row and t-th column of the second path image; e (R) is a second average value of pixel points of the second path image; w (W) s,t E (W) is the first average value of the pixels of the first path image, wherein the values are the values of the pixels of the s-th row and the t-th column of the first path image;
and comparing the contact ratio of the first path image and the second path image with a preset contact ratio, and judging whether the first path and the second path completely coincide or not according to a comparison result.
6. A method for automatic lay-out of filaments based on fiber weaving according to claim 3, wherein determining a partial second path which is not coincident as a path to be corrected, comprises:
determining a first path of the misaligned part as a reference path;
and determining the deviation angle and the deviation length of the path to be corrected relative to the reference path, and correcting the path to be corrected based on the deviation angle and the deviation length.
7. The automatic layout method of fiber yarn based on fiber yarn braiding according to claim 2, wherein a plurality of layout areas included in the mapped image are rendered, and a corresponding image layer is generated and displayed by a display module based on an actual pixel value of each pixel point in the layout areas.
