The accuracy of phase-measuring profilometry (PMP) is greatly influenced by the environmental light,especially in the outside of the room.The error caused by the change of the environmental light is analyzed.A method to calibrate the grey scale of the fringe pattern acquired by the CCD camera is presented.By using the method,the error is greatly restrained.
