Evaluating Fabric Wrinkle Degree with a Photometric Stereo Method

A method is proposed for fabric 3D surface reconstruction using a photometric stereo method. As an investigation of the efficacy of the method, the 3D surface of an AATCC standard wrinkle pattern is reconstructed and its wrinkle degree is measured using four index values that indicate the variation of the surface height value. The results show that there is a good linear correlation of the index value with the wrinkle degree of the pattern.
