Abstract

In this paper, a one-shot composite pattern based on three-step binary stripe pattern is developed to meet the demand of real-time 3D shape measurement for complicated objects. Theoretical analysis and numerical simulation prove that the proposed pattern can provide higher accuracy than the composite pattern based on the traditional three-step phase shifting. Furthermore, the significant advantage for the proposed composite pattern is that it can provide the unique location of the stripe boundary, resulting in the elimination of the ambiguity which usually arises for measurement of complicated object with the phase shifting method. The proposed composite pattern has been implemented to measure three different complicated objects. The results demonstrate that it is appropriate for the real-time 3D shape measurement.
