ABSTRACT

The phase shift method of fringe projection technique has attracted much attention for its high-precision, high-speed, and flexible measurement capabilities. But the increase of the phase shift step also means that the measurement is more time-consuming. Compared with at least three steps phase shift method, the two-step phase shift method is important to coordinate measurement speed and accuracy. This paper proposes a new method based on neural network to solve the wrapped phase map. The simulation results show that this method is an accurate and efficient two-step phase shifting phase solution method.
