An embedded three-dimensional (3-D) digital imaging scheme with a parallel fixed-point digital signal processor (DSP) is presented, which is based on temporal phase unwrapping and DLP digital projection technique. This scheme utilizes an embedded hardware structure with aid of parallel DSP to realize a pipeline procedure of the automatic analysis of fringe patterns, fringe patterns generation, fringe projection, and data acquisition. The software pipeline is also adopted in the procedure phase demodulation and phase unwrapping. The time of phase reconstruction with five-step phase shift is 0.89s for 262144 coordinates, and the fringe image processing speed is up to 39.5 f/s (frames per second), so it can meet the need of video-rate fringe images processing. Experiment results show that this embedded DSP imaging system is fast, reliable, low power cost, and it will be suitable for a wide range of practical measurement application.
