摘　　要：为了改进传统悬垂性的测量方法，客观反映织物的悬垂性，利用微软的Kinect传感器提出了一种单向悬垂性三维测量方法。通过Kinect传感器获取织物试样的三维悬垂模型并保存为STL（立体光造型）格式文件，通过删除杂质、裁剪、矫正图像得到织物试样的三维悬垂投影，水平截取悬垂投影图像，求出水平面与试样轮廓的交线，将这些交线整理成头尾相连的一条直线段并滤波得到二维悬垂投影曲线，通过相关算法识别出该投影曲线的波峰、波谷点，提取了表征单向悬垂程度指标（单向悬垂系数）和悬垂形态指标（峰数、峰对称性系数等），建立了单向悬垂性评价体系，并通过实验与标准测试悬垂性的方法以及人为主观评价方法做了相关性分析，结果发现单向悬垂指标在描述织物悬垂性上与传统方法和主观评价法均一致，实现了织物悬垂性的三维测量。To improve the traditional measuring method for drapability and objectively reflect the drapability of fabric,a three-dimensinal(3D)measurement method for unidirectional drapability was proposed by using Microsoft Kinect Sensor in this paper.The 3D draping model was captured by Kinect Sensor and saved as STL(stereo lithographic)format files;then,the 3D draping projection was obtained by removing impurities,cutting and correcting the images;the projection drawing was intercepted horizontally to get the intercepting lines between the horizontal plane and the sample outline;such intercepting lines were systemized into a linear segment and the two-dimensional draping projection curve was obtained after filtering;the wave crest and trough point of this projection curve were recognized through related algorithm;the characterized unidirectional draping extent indexes(unidirectional draping coefficient and peak number etc.)and draping aesthetic indexes(peak symmetry coefficient etc.)were extracted;in addition,the evaluation system of unidirectional drapability was established;moreover,relevant analyses were made through experiments and standardized tests for drapability and men’s subjective assessment.The correlation analysis results show that the unidirectional fabric draping parameters on describing fabric drapability are consistent with both the traditional method and subjective evaluation method.This method realizes the 3D measurement of the fabric drapability.
