Abstract

A compact 3-D shape measurement system based on the combined stereovision and phase shifting method has been developed, which consists of a miniature projector and two small cameras arranged as a stereo pair. The projector projects sinusoidal phase shifted fringe patterns, which are captured by both cameras simultaneously. The two phase maps calculated are used for stereo matching. The 3-D shape of the object is then reconstructed by the triangulation method. This research focuses on improving the resolution and accuracy of the measurement system by using a sub-pixel stereo matching method, a multi-image averaging method, and an error compensation method. Experimental results are presented to show the effectiveness of the proposed methods in improving the resolution and accuracy of the system.
