The three-dimensional measurement technique using binary pattern projection with projector defocusing has become increasingly important due to its high speed and high accuracy. To obtain even faster speed without sacrificing accuracy, a ternary Gray code-based phase-unwrapping method is proposed by using even fewer binary patterns, which makes it possible to efficiently and accurately unwrap the phase. Theoretical analysis, simulations, and experiments are presented to validate the proposed method's efficiency and robustness.
利用投影仪散焦的二值图案投影的三维测量技术因其高速度和高精度而变得越来越重要。为了在不牺牲精度的情况下获得更快的速度，提出了一种基于三值格雷码的相位展开方法，该方法使用更少的二值图案，从而能够高效且准确地展开相位。通过理论分析、仿真和实验来验证所提方法的效率和鲁棒性。
