A new improved method based on active controlling of phase-shifting was presented .In the meas-urement, three frames of sinusoidal gratings with the same known phase-shifting value are projected to the measured object one by one , while three frames of distorted fringes are captured by CCD camera synchronous-ly.3D shape of the object is measured according to improved phase extracting algorithm .The computer simu-lations and experiments show that the improved method can effectively improve the measurement accuracy .
