本文提出了一种新的多点法，即3-2-1传感器布局的六点法和3 × 3传感器布局的九点法，用于加工平面的二维轮廓测量。进行了Monte Carlo模拟，并对所提出的方法的性能进行了研究。结果表明，六点法是仅用六个位移传感器计算平面形状的最小配置，可获得与简单九点法等效的结果。在九点平均法中，重建轮廓的标准偏差的最大值和平均值分别比简单九点法降低了68%和81%。提出了平均俯仰误差的改进九点法来提高数据连接精度，该方法降低了标准差，但效果有限。
New multi-point methods, the six-point method of 3-2-1 sensor layout and the nine-point method of 3 × 3 sensor layout, have been proposed as the two-dimensional profilometry for a machined flat surface. Monte Carlo simulations were carried out and properties of proposed methods were examined. As a result, it was shown that the six-point method, the minimum configuration that calculates the planar shape with only six displacement sensors, can obtain the equivalent result to that of the simple nine-point method. In the nine-point method with averaging, it was confirmed that the maximum and average values of the standard deviation of the reconstructed profile were reduced to 68% and 81%, respectively compared with simple nine-point method. The improved nine-point method that averages the pitching error to improve the data connection accuracy also proposed and this method reduced standard deviation, but effectiveness is limited.
