Abstract
Traditional fabric appearance evaluation method mainly relies on subjective and manual operation, which is not uniform and time-consuming. In this paper, one set of self-developed 3D reconstruction system and method based on photometric stereo is proposed for objective fabric appearance evaluation. A photometric stereo image acquisition system equipped with multi-directional lighting sources is developed for the 3D surface reconstruction. Lighting and camera calibration is conducted to obtain the position of light sources and the intrisic parameters of digital camera. Our experimental results show that 3D fabric surface could be reconstructed effectively based on photometric stereo vision method, it has the potential to be used for fabric appearance evaluation.
