摘要
根据因瓦条码水准标尺的使用与检定要求,利用图像处理、数据实时传输与控制技术建立因瓦条码水准标尺竖向自动检测系统。本系统集成了双频激光干涉仪、双CCD相机、竖向运动控制设备、环境采集与数据自动处理软件等子模块,在尽量还原因瓦条码水准标尺使用状态的情况下,完成了检定工作,较其他检测系统具有占地空间小、操作简单、检定可靠性更优、效率更高等优点。
According to the requirements of the use and verification of Invar bar-coded levelling staffs,the vertical automatic detection system of Invar bar-coded levelling staffs is established by using the technology of image processing,real-time data transmission and control.This system integrates several sub-modules,such as dual-frequency laser interferometer,dual-CCD camera,vertical motion control equipment,environment acquisition and automatic data processing software,etc.,finish the calibration of Invar tape measure.Compared with other detection systems,it has the advantages of small space,simple operation,better reliability and higher efficiency.
