针对以往关于两点法测量直线度的文献中要求两传感器端部严格对齐的问题,本文对此进行了数学分析和计算机仿真,证明对齐误差并不影响最后的误差分离准确度,同时可在一定程度上降低对传感器安装准确度的要求 Aiming at the problem that the two sensors must be strictly aligned in the literatures about measuring the straightness of two-point method in the past, this paper carries on the mathematical analysis and the computer simulation to prove that the alignment error does not affect the accuracy of the final error separation, To the extent possible, reduce the need for sensor installation accuracy
