Embodiment Construction
[0038] The present invention will be further explained below in conjunction with specific embodiments and drawings.
[0039] In order to evaluate fabric morphology and style more objectively, the present invention proposes a fabric morphology feature extraction and fabric morphology style evaluation method based on dynamic sequence images. At the same time, some fabric dynamic feature parameters and fabric morphology style evaluation parameters are proposed, so as to be based on these parameters. Make objective comparisons and evaluations.
[0040] With figure 1 The two monocular high-speed cameras are shown as examples, that is, one is set on the left and right to analyze the method of fabric morphological feature extraction and fabric morphological style evaluation. The specific steps are as follows: ①Using multiple CCD digital cameras to move the fabric The process of dynamic shooting, the steps of obtaining multi-frame dynamic sequence views of fabric movement; ②Using computer ...

The invention relates to a textile form and style evaluation method based on a dynamic sequence image and belongs to the field of spinning. The textile form and style evaluation method based on the dynamic sequence image is characterized by comprising the following steps: carrying out dynamic shooting on a movement process of a textile fabric by using a CCD (Charge Coupled Device) digital camera to obtain a multi-frame dynamic sequence view of textile movement; extracting characteristic points from all the shot views of the same frame; carrying out stereo matching on the characteristic points of the corresponding views and calculating three-dimensional coordinates of matched points; calculating basic movement physical quantities of a textile from the obtained three-dimensional coordinates of the matched points; extracting dynamic characteristic parameters of the textile according to the basic movement physical quantities and movement characteristics of the textile; measuring physical performances of the textile; carrying out factor analysis on the measured physical quantities; calculating an incidence relation between the dynamic characteristic parameters and the physical performances of the textile; combining a form and style evaluation factor based on the measurement process of the physical performances to obtain a form and style evaluation factor based on the dynamic sequence image to finish the evaluation of the form of the textile.
Description
Technical field [0001] The invention relates to a fabric shape and style evaluation method, in particular to a fabric shape and style evaluation method based on dynamic sequence images. Background technique [0002] The morphological characteristics of the fabric refer to a kind of sensory effect involving mental mapping produced by the line shape formed in the shaping of the fabric to stimulate the visual organs. It can be expressed indirectly through physical concepts such as fabric rigidity, flexibility, shape and shape stability, that is, the physical and mechanical properties of clothing fabrics (such as stretching, shearing, bending, etc.) affect the appearance of clothing. [0003] In the 1970s, the Textile Style Evaluation and Standardization Committee (HESC) headed by Professor Yoshio Kawabata of the Department of Polymer Chemistry at Kyoto University developed the Kawabata Style Instrument (KES-F) system based on the starting point of reflecting the characteristics of the...
