| Abstract: | Two - dimensional Fourier transform profilometry (2D FTP) without frequency - moving for data acquisition of three - dimensional transformation of fabric appearance is proposed. In this method, Crossed - Optical - Axis Geometry and phase unwrapping technique based on digital weighted filter and reliability mask are employed. Experimental results of shape measurement for several fabric appearance are given. |
