摘要:
为避免试样比照法的偶然性和不确定性,文章提出一种基于综合指标分析织物褶裥等级的方法。以三维激光扫描仪获取的褶裥模板点云为研究对象,通过对三维参考面重建将Z轴作为褶裥高度进行分析,对点云进行预处理得到50 mm×50 mm的点云集合并提取三维特征指标。首先分析单个特征指标与褶裥等级的拟合方程和相关系数,结果表明单个指标不能很好地反映褶裥等级,最后运用逐步回归分析法建立综合特征指标与褶裥等级的模型。采用含有褶裥织物样本检验模型,结果表明主客观评价的吻合度达90%, 能合理反映织物褶裥等级,为客观评价织物褶裥等级提供依据。
Abstract:
In order to avoid the contingency and uncertainty of the sample comparison method, a method based on comprehensive indexes to analyze the pleat grade of fabrics is proposed. Pleat template point cloud obtained by 3D laser scanner was taken as the research object. The Z axis as pleat height was analyzed by the reconstruction of the 3D reference plane, and pretreatment of the template point cloud was conducted to obtain a point cluster of 50mm x 50mm. Meanwhile, the three-dimensional characteristic indexes were extracted. Firstly, the fitting equation and the correlation coefficient between the individual characteristic index and the pleat grade were analyzed. It was concluded that the single index could not well reflect the fabric pleat grade. Finally, stepwise regression analysis was used to establish a model of comprehensive characteristic index and pleat grade. The model was tested with the samples containing pleated fabrics. The results showed that the coincidence degree of subjective and objective evaluation was 90%, which can reasonably reflect the fabric pleat grade, This paper provides the basis for the objective evaluation of fabric pleats.
