基于视频序列的织物折皱回复角动态测量

针对现有织物折皱回复性能测量方法存在仅能静态测量某时刻织物折皱回复角度值的不足，本文提出了基于视频序列的织物折皱回复角度动态测量方法。按AATCC66-2008标准要求，以SDL-M003折皱回复角试验机的负载装置压试样，再将试样置于视频序列采集系统中，对采集到的单帧图像依次进行二值化、细化预处理，采用Hough变换检测图像中织物折皱回复两翼对应的角度，进而获得折皱回复角。试验结果显示，基于视频序列的方法与AATCC66-2008测量方法的结果接近，表明了基于视频序列方法的可行性，并且该方法可以精确描述织物折皱回复的动态过程，为实现新的折皱回复性能指标的提出奠定了实验基础。

Dynamic measurement of fabric wrinkle recovery angle by video sequence

Aiming at the deficiency that the static measurement method just can measure fabric wrinkle recovery angle at some moment, this paper presents a novel method to measure the wrinkle recovery angle by video sequence. The SDL-M003 loading device is used to press a sample according to AATCC 66-2008. Then place the folded sample in the video sequence system and record a 5 min video of the recovery period. Each video frame is processed sequently by thinning algorithm and Hough transform to get the wrinkle recovery angle. The test results of the video sequence method and the AATCC 66-2008 test method are close to each other, which indicate that our new method is feasible. The obtained angles of the 5 min recovery period provide more information to determine wrinkle recovery behaviors of fabrics, as well as lay a foundation for the proposal of new wrinkle evaluation criteria.
