摘　　要：针对目前电子水平仪手动检定装置的不足,提出了基于机器视觉的电子水平仪自动检定系统。具体介绍了系统的结构、工作原理,对示值自动判读方法和系统软件,并对检定结果的不确定度进行了分析评定。通过实验将自动检定结果和人工检定结果进行比较,验证了自动检定系统的可行性和有效性。Aiming at the shortcomings of current manual verification devices for electronic levels, this paper puts forward an automatic verification system for electronic levels based on machine vision. The structure, working principle of the system, automatic interpretationmethod for the indicating values of electronic levels and system softwareare detailedly introduced. The uncertainties of verification results areanalyzed and evaluated. The feasibility and effectiveness of the automatic verification system has been verified by comparing the results of automatic test and manual test.
