阐述现阶段品牌服装防伪现状及应用二维条码在服装吊牌上的可行性.针对商标图像以色块图为主、颜色少的特点,在对商标图像进行边缘检测、轮廓跟踪及轮廓特征信息提取的基础上,提出了一种商标图像大比例压缩算法,实现将服装吊牌中商标和服装其他特征信息制成一种带PDF417二维条形码的服装吊牌.通过识读出二维条码中的服装文字信息及商标图案和服装吊牌上信息相对比,实现服装吊牌的防伪.%The research on the current situation of anti-counterfeit of branded clothing,and the feasibility analysis of the application of two-dimensional bar code in clothing label was conducted. In view of the characteristics of the trademark and based on trademark image edge detection,contour following and contour feature information extration, a large scale compression algorithm of logo was proposed, and a two-dimensional PDF417 bar code was created by integrating bar code image with other clothing characteristic information, while restoring clothing text message and brand image by reading off the information of two-dimensional bar code,thereby distinguishing the original from the fake.
