英文摘要：

An embedded 3-D vision measurement scheme with an low-power high speed digital signal processor （DSP）, is presented to overcome those disadvantages of the traditional 3-D digital imaging device based on PC. This scheme is based on the principle of phase measurement profilometry, and implements structure light illumination by the digital projection technique. The DSP and FPGA hardware along with multithreads technique are adopted to realize a pipeline process of the fringe coding, data acquisition and fringe analysis. Finally the measure experiment shows this system can implement fast and true measurement of 3D profile.
