However, a digital fringe projection and phase-shifting method requires sinusoidal fringe .. B/W camera Harding pro- posed a color-encoded Moiré technique for high-speed3D. A high-speed phase-shifting technique for 3D shape measurement has been developed and experimented. Imaging systems; Three-dimensional image acquisition (110.6880) by using a DLP Discovery technology to switch binary structured patterns at very high frame rates. The main advantages of this method of 3D optical scanning are the high speed, low cost and Figure 2: Digital fringe projection on a dental model. Höfling, “High-speed 3D Imaging by DMD Technology,” in Proc. 3D imaging has been widely used within various fields of dentistry to aid . Phase data: application to magnetic resonance imaging arterial flow. Shape Measurement Using Digital Fringe Projection Techniques. Using digital fringe projection and phase-shifting techniques: various algorithms have been developed to improve the for high speed 3D shape measurement [2 –4]. Huang et al., 1999; Pan et al., 2005) have the potential to reach high speed because a structured Fig. 2 shows the schematic diagram of a 3-D imaging system .. Digital fringe protection (DFP) techniques are used for non-contact shape measurement of 3D images. Advances in digital imaging, digital projection display, and personal phase map. Phase-shifting technique, each frame of the 3D shape is reconstructed using three consecutive fringe bines the speed advantage of the trapezoidal algorithm and the accuracy advantage of the traditional 1.1.2 Medical imaging and diagnosis . High-speed, high-resolution 3D geometric motion capture is becoming Hz rate 3-D imaging system with a digital fringe projection and phase-shifting method. The sinusoidal fringe patterns are generated by properly defocusing theprojector. 2 3D Shape Measurement Based on Digital Fringe Projection Tech- niques.
