单点激光三角法测距及其标定

Distance Measuring and Its Calibration Using Single-point Laser Optical Triangulation

介绍了一种快速准确的非接触测距方法,阐明了单点激光三角法测距的原理及其测量系统的主要组成。针对测量用的光敏传感器-电荷耦合器件(ChargeCoupledDevice,CCD)之标定曲线的非线性特性,着重叙述了用逐段折线逼近该标定曲线的方法,并给出了具体的算法程序。

Introduced a kind of fast and accurate non-contact distance measuring.The principle of single-point laser optical triangulation and its main construction and described.Due to the non-linear characteristic of the used light-sensitive transducer-CCDs calibration curve,the method of using piecewise linear line to approximate CCD calibration curve and the algorithm program are given in detail.
