摘要：
针对传统立式罐容量计量方法存在工作效率低、自动化程度低、劳动强度大、安全隐患大等缺点,提出一种基于三维激光扫描技术的大型立式罐容量计量方法。通过运用三角形面积积分法和截面积高度积分法,计算出立式罐不同液位高度对应的容积值。并设计试验比对系统,选取一个6 000 m3的油罐作为研究对象进行内测试验,结果表明三维激光扫描方法具有良好的重现性,以传统几何测量法的结果作为参考,验证该方法的有效性,并且能够显著提高检定效率;选取一个5 000 m3的油罐作为研究对象进行外测试验,结果表明该方法在不规则罐容量准确计量、罐体的变形和不规则监测等方面具有独特的优势。

Abstract: Since traditional vertical tanks volume measurement methods have some shortcomings such as low productivity, low degree of automation, high labor intensity, high security risks,and so on. This paper presented a large-scale vertical tank volume metrology method based on 3D laser scanning technology. The volume value corresponding to the height of different level is calculated by making use of the triangle area integration(TAI) method and cross-sectional area height integration (CAHI) method and a test system was designed. Selecting a 6 000 m3 tank as the object of the study, internal measured results showed that the method had good repeatability and reproducibility and was verified the effectiveness by using the geometric measurements of capacity as a reference, significantly improved the efficiency of metrology test. External measured results were performed and showed that the proposed method had unique advantages in accurate measurement of the irregular tank capacity and tank deformation monitoring by selecting a 5 000 m3 tank as the study object.
