英文摘要：

A 3D non-contact coordinates system composed of a cloth table, a set of sensor and a PC was built to measure the garment cloth configuration. The principle and data preprocessing were described in detail..It was free of system errors and random errors which were caused by measuring force, and implemented zero-contact-force-measurement. Combined with grating projection technique and digital phase shifting technique, it made full use of phase-shifting and optical triangulation. The research results showed that the system can obtain the cloth digital signal appearance quickly and accurately. It can provide valid data in the cloth appearance objective evaluation.
