| Research Abstract |
We have developed single frame 3D measurement system using moving stripe pattern projection based on depth dependant modulation transfer function. When the stripe pattern with a certain spatial frequency component moves on the object, the brightness on it has temporal variation which is determined by its velocity and spatial frequency. The amplitude of that temporal variation decreases gradually with an increase in distance from focal point because of low-pass filter characteristics of the projection lens. The correlation image sensor can captures temporal variation in single frame, so that the 3D shape was reconstructed. We have confirmed those principles by some experiments.
