二项式曲线;
In this method, binomial curve is used to approximate the intensity of the captured images, meanwhile, least square fitting method is used to compensate the phase error, and in this way, system error caused by the gamma nonlinearity of the projector is reduced greatly.
该方法采用二次多项式最小二乘拟合的方法近似输出条纹光强分布,实现对相位波动误差的补偿。
