织物静态悬垂性测试过程中图像采集问题的研究

摘要

The static drape of fabric was tested by the dynamic drape instrument and home-made assembly instrument DIY based on the static drape instrument of fabric.The selection of image acquisition mode and the problem of overlooking blind angles were analyzed in the testing process.The research showed that it is appropriate to collect the images directly in the form of upper lighting when the color of pure fabric had great difference with the background or the patterns of coloured fabric had great difference with the background, and it is appropriate to collect the images directly in the form of bottom lighting when the sample fabric was translucent.When the problem that the overlooking blind angles in the image acquisition of the upper front lighting led to the appearance of unclear images appeared, it was solved by increasing the radius of the support plate or increasing the space between the camera and the sample.%分别采用织物动态悬垂性风格仪和基于织物静态悬垂性风格仪自行组装的DIY仪器,对织物的静态悬垂性进行测试,并对测试过程中图像采集方式的选择和俯视死角问题进行分析.研究结果表明:当纯色织物的颜色与背景颜色反差较大或花色织物的图案花色与背景颜色相差较大时,宜采用上打光直接采集图像;当测试织物为半透明织物时,宜采用下打光直接采集图像;上打光顺光采集图像过程中出现俯视死角导致的图像采集不清晰问题,可通过增大支持盘半径或增大相机与试样间距的方法解决.
