摘要
本文提出一种用于卧式罐（含铁路罐车）椭圆竖截面直径的数显光学测量法。它具有测量准确度高、适应性强、不受风力影响等特点。实验与分析表明，对２～３．４ｍ的直径，其测量的扩展不确定度（９５％置信概率）为０．７ｍｍ。
This paper presents a new digital optical method for measuring oval vertical section diameter of horizontal tank (including railway transport tank). This method shows advantages of high accuracy and wide applicability, and not be influenced by wind-force. The experiment and analysis show that the total measurement extended uncertainty is 0.7mm (the confidence probability is 95%) for tank diameter of 2～3.4m.
