In this paper, we propose a new method for measuring fabric wrinkling based on integrating photometric stereo and image analysis techniques. In the traditional method. wrinkled fabrics are evaluated subjectively according to the grades of replica plates supplied by the American Association of Textile Chemists and Colorists (AATCC). But due to the disadvantages of subjective methods. which are tedious, time-consuming, subjective, and so on. image analysis techniques are used in this work as an objective method. However, serious problem occur when colored and patterned fabrics are tested with conventional images and processing techniques, although they work for tests of solid fabrics. In this paper, a photometric stereo method is used to extract three-dimensional surfaces of fabrics and successfully eliminate the influence of color and pattern. Image analysis techniques are furthered to extract wrinkling features of these reconstructed 3D images, and there is a good linear correlation between objective parameters and subjective AATCC grades.
