摘要

在分析空间曲线的曲率检测误差产生原因的基础上

研究了标定方向空间曲率和检测方向信号的关系。在确定曲率分量和检测信号的关系之后

提出了一种校正标定误差、提高空间曲率检测精度的方法

并介绍了该方法的几何意义。该方法不仅可以用于空间曲率检测的标定工作

也可适用其他一些空间矢量的检测工作。

Abstract

The causes for spatial curvature measurement errors are analysed

and the relationship between the curvature in the direction of calibration and the signal in the direction of measurement is discussed. With a relevant formula established

a new method is proposed for the correction of the calibration error. The geometric meaning of this method is then defined not only for measurement of spatial curvature

but also for inspection for some other spatial vectors.
