摘　　要：为实现经多次洗涤后织物色牢度等级评定方法的客观化,提出一种基于数字图像处理的织物耐洗涤色牢度等级评定方法,并探讨了图像法用于评定织物耐洗涤色牢度的可行性。该方法首先利用扫描仪对AATCC变色灰卡和沾色灰卡进行扫描,并计算灰卡各等级的灰度值,然后对变色和沾色灰卡各等级与其对应灰度值的关系进行分析,通过曲线拟合得到变色等级-灰度值方程与沾色等级-灰度值方程。为验证图像法评定结果,根据AATCC 61—2010标准规定对相同洗涤程序下的试样进行人工目视评级。结果表明基于数字图像处理的织物耐洗涤色牢度等级评价方法与人工目视评定结果具有较高的一致性,而且图像方法更为简便、客观和精确。In order to evaluate the color fastness grade of fabric after frequent laundering objectively, a method based on image analysis is proposed, and the feasibility of this method is also discussed. Firstly, the images of different grades of the gray scale for color change and gray scale for staining of AATCC 61-2010 are scanned to calculate their corresponding gray values. Secondly, the equation of grade for color change-gray values and the equation of grade for staining-gray values are fitted by analyzing the relationship between the gray values of color change and its grade, respectively. To verify the effectiveness of the method proposed in this paper, the test results are compared with the ones of visual evaluation according to AATCC 61-2010 after the same washing conditions. The experimental results indicate that the evaluation method for color fastness grade based on image processing has good consistency with the visual evaluation method, while the former is much simpler, and more objective and accurate than the latter.
