Paper Abstract
In this paper a 3D shape measurement system based on the grating method was developed. The system consists of two
CCD cameras and a DLP projector. The multi-frequency heterodyne principle was presented to overcome the
unwrapping problem of phase functions, and a phase-to-coordinates conversion algorithm was proposed to reconstruct
the 3D geometry from the unwrapped phase map. To demonstrate the performance of this 3D measurement system, a
face model was measured, and the reconstructed 3D geometric surface is very smooth with details. Additionally, a ladder
with one step was measured. The result shows the system can measure the discontinuous object and get high
measurement precision.
