基于三维激光传感器的圆柱度测量新方法

摘要

The system of 3D laser scanning mainly consisting of 3D laser displacement sensor,laser line source,coded tensile displacement sensor and stepper motor was introduced.The system was applied in the measurement of 3D graphics,round beating of a location,cylindricity and axis straightness.The structure and principle of 3D laser scanning systems were introduced and the measurement process was established for the estimation of cylindricity error.A measurement software was designed based on the software developing platform LabVIEW.%介绍了由三维激光位移传感器、激光线光源、编码器式拉伸位移传感器以及步进电机搭建的三维激光扫描测量系统.该系统可以一次测得圆柱体的三维图形、某一位置的圆跳动以及圆柱度、轴线直线度等参数.阐述了该三维激光测量系统的结构组成和工作原理,给出了圆柱度误差的具体测量评定过程,并基于LabVIEW开发平台设计出了轴类零件表面形状误差测量软件.
