linear rectification meaning in Chinese

线性整流

Application of non - linear rectification in impact flowmeter
非线性校正在冲板流量计中的实现
Finally , a new 3d surface ranging method based on a digital fringe projection and shifting technique is systematically studied and non - linear rectification algorithms which reduce measurement error is proposed . at the same time , the noise - immune phase unwrapping algorithm is deeply studied and a new algorithm for phase unwrapping of phase map is proposed . experiment make known the algorithm can reduce measurement error , bypass the noise points automatically , solve the problem of the shade sheltering or cavity , overcome the error propagation problem and better results have been obtained
论文最后系统研究了基于数字相移条纹投影曲面三维测量方法，创造性地提出了一种减小测量误差的非线性校正算法，取得了预期的效果；同时对相位去包裹算法进行了较深入研究，提出了一种噪声图像相位去包裹方法；实验表明该方法能减小非线性测量误差，自动避开噪声点和间断点，获得了满意的结果。
