英文摘要：

The 3-D measurement apparatus is developed based on four-step phase-measuring method, which belongs to phase detection of projected gating. The measurement theory is introduced and the four-step phase-measuring method which includes designing the optics-projection system, the machine of phase-measuring, and collecting module of image is carried out. The C8051 F340 is the main COMS chip of the control system, and with which the corresponded software is designed. The apparatus can be used for 3-D measurement in industry and be suitable for many other occasions too. It has many merits, such as small volume, convenient control, fast measurement velocity, prefect precision, and using USB for communications, so it is convenient for renlotion.
