采用激光测量技术客观评价织物褶裥等级
Objective evaluation of fabric pleats grade by laser measurement technique
摘要
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 50 mm × 50 mm. 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.关键词
