Paper Abstract

Parameters affecting the sensitivity of a 3D measurement system using the phase shifting technique were investigated. A simple wedge object was used for the experiments to study the factors without the possible complication caused by using a complex object. A calibration procedure was derived to investigate to what extend the important parameters affected the results of the depth measurement by the use of the phase shifting method. These parameters were the pitch, projector magnification, camera magnification, and projection angle. The results of the experiments are presented and possible reasons for such results are discussed in this paper.
