Abstract
The paper builds a real-time system of 3D profile measurement using structured-light imaging. It allows a hand-held object to rotate free in the space-time coded light field, which is projected by the projector. The surface of measured objects with projected coded light is imaged; the system shows surface reconstruction results of objects online. This feedback helps user to adjust object's pose in the light field according to the dismissed or error data, which would achieve the integrality of data used in reconstruction. This method can acquire denser data cloud and have higher reconstruction accuracy and efficiency. According to the real-time requirements, the paper presents the non-restricted light plane modelling which suits stripe structured light system, designs the three-frame stripes space-time coded pattern, and uses the advance ICP algorithms to acquire 3D data alignment from multiple view.
