摘　　要：传统的玻璃量器的检定通常是由人工操作,人为操作误差和读数误差会导致检定结果有偏差。提出了一种基于图像处理技术的液位检测方法,为自动检定过程提供误差小、重复性低的液位信息,并通过使用自动加液装置配合电子秤进行了100 mL量筒的不确定度实验。结果显示,自动检定的扩展不确定度为0.096 mL,明显优于人工检定的0.160 mL,验证了该方法在提高了玻璃量器检定的准确性、稳定性和及时性方面的显著效果。The traditional verification of glass gauge is usually manual operation,and the manual operation error and reading error will lead to the deviation of the verification result.In this paper,a liquid level detection method based on image processing technology is proposed,which provides liquid level information with small error and low repeatability for the automatic verification process.The uncertainty experiment of 100 ml measuring cylinder is carried out by using the automatic liquid filling device and electronic scale.The results show that the expanded uncertainty of automatic verification is 0.096 ml,which is significantly better than that of manual verification of 0.160 ml,which verifies the significant effect of this method in improving the accuracy,stability and timeliness of glass gauge verification.
