Paper Abstract

According to Sampling Theorem and image processing, structured light system has some limits, such as the measurement resolution is restricted, some little gaps can not be measured and there are some errors or lost data on the border of surface. A novel rotatable interlaced coding in real-time system of 3D information acquisition using structuredlight imaging is proposed. It is consisting of two free directions of three-frame space-time light pattern, which can acquire the denser 3D data from a single viewpoint. It can decrease the error from range image registration and advance the system accuracy. The paper builds a real-time system of 3D profile measurement using structured-light. It allows a hand-held object to rotate freely in the space-time coded light field, which is projected by the projector.
