Embodiment Construction
[0029] The present invention will be further described below.
[0030] A method for evaluating the pleat level of clothing, the specific steps are as follows:
[0031] Step 1. Use a three-dimensional laser scanner to scan the pleats of the garment to be tested with a single pleat, and obtain a point cloud array containing three spatial position information (coordinate values in the coordinate system) and three vector information ( That is, the information of any point in the point cloud array consists of three spatial position information and three vector information).
[0032] Step 2. Fit the reference surface of the point cloud array obtained in step 1: Import the point cloud array into GeomagicStudio 12 reverse engineering software to obtain a discrete point map, and click the "Point Cloud Coloring" button. Check the "Global Coordinate System" in the "View" option, so that three global coordinate axes appear in the discrete point graph. Select m discrete point groups on...

The invention discloses a method for evaluating the pleat level of clothing. The existing pleat grade evaluation methods are easily affected by individual subjective factors, and the evaluation results are inaccurate. The present invention is as follows: 1. Scan the pleats of the garment to be tested to obtain a point cloud array. 2. Fit the reference surface to the point cloud array obtained in step 1. 3. Denoise and crop the point cloud array obtained in step 2. 4. Calculate the interquartile range, average offset and roughness of the point cloud array obtained in step 3. 5. Determine the level of pleats on the garment to be tested. The invention can complete the assessment of the pleat level of the garment to be tested by performing three-dimensional scanning on the garment to be tested, and has high efficiency. The evaluation result of the invention is accurate and objective, and can avoid the error and uncertainty of manual subjective evaluation. The invention can avoid the influence of clothing color, pattern and flower pattern on the evaluation result.
Description
technical field [0001] The invention belongs to the technical field of textile and garment performance testing, and in particular relates to a method for evaluating the pleat level of garments. Background technique [0002] Pleats are a common shape on clothing. For example, for trousers, pleated skirts and other clothing, pleats are an important attribute that affects their shape, so it is very important to accurately evaluate the pleat level of clothing. At the same time, the evaluation of pleats grade is also an important index for the evaluation of clothing appearance. In the prior art, the pleat grade is mostly evaluated by the AATCC-88C standard sample comparison method. This is a subjective evaluation method, the evaluation result is easily affected by personal subjective factors, and the evaluation result is not accurate. Therefore, it is very important to design a method for objectively evaluating garment pleats that can avoid the influence of subjective factors. ...
