摘　　要：文章提出基于3D扫描技术的织物悬垂性测试分析方法。利用3D扫描仪采集织物图像空间点数据,通过点云拼接、去噪、填充等平滑织物悬垂曲面得到扫描实体。沿着扫描实体的Z轴线方向等距离剖切得到多个XOY平面,并提取各个平面的悬垂波数、波峰半径等参数。实验结果表明,悬垂系数与传统方法测得的悬垂性指标相关性高,而织物各切面层波形个数、波形稳定高度、波峰半径与波谷半径变化趋势等参数直观地反映织物在三维空间中悬垂曲面形态变化,为评价织物悬垂性提供新的方法。This paper presents a method of fabric drape test based on 3 D scanning technology. Space point data of fabric images were collected by 3 D scanner,and the scanning fabric was gained through point cloud splicing,denoising and filling. Then,multiple XOY planes were obtained by equidistantly sectioning along the Z-axis direction of the scanning fabric,and the parameters such as the number of waves and the crest radius of each plane were extracted. The experimental results showed that the drape coefficient was highly correlated with the drape index measured by the traditional method. The parameters such as the number of waves,the stable height of waves,the trend of crest radius and trough radius reflect the morphological changes of the drape in the three-dimensional space.This paper provides a new method for evaluating the fabric drape.
