Abstract

In recent years, we have been developing a high-resolution, real-time 3-D shape measurement system based on the phase-shifting method. As the phase shifting algorithm for the system, the three-step algorithm has been our choice because it requires only three fringe images, which is the minimum among all the existing algorithms. Less number of images means faster image capture as well as processing, which translates into higher measurement speed. However, our experiments show that even with the three-step algorithm, the processing speed is still not fast enough for real-time 3-D shape reconstruction when an ordinary personal computer is used. The bottleneck lies in the calculation of phase, which involves a computationally time-consuming arctangent function.
