Abstract  For the liquid volume measurement of volumetric glass gauge, a liquid level measurement method for micro liquid volume based on laser and machine vision technology was proposed. A volume table for correspondence relationship of liquid level and capacity in the standard glass gauge was established. The corresponding value of liquid volume can be obtained by measuring the liquid level. Measuring the liquid level of the standard glass gauge is the main point in the method. Liquid level measurement combined with computer and digital image processing technology, and used high-resolution camera and image processing software to extract feature element. High-precision volume measurement was realized, a comparative test with the static measure method was also designed, and validated the method. For the 100mL glass container, the measuring accuracy is better than 0.2%, the expanded uncertainty of the fitting algorithm is 0.137% (k=2), and the repeatability of measurement is 0.08%.
