针对常规立式罐变形检测方法劳动强度大、效率低、自动化程度不高等缺点,提出了一种基于三维激光扫描技术的立式罐变形检测方法。分析了基于三维激光扫描技术的立式罐罐体圈板半径、圆柱度、垂直度和高度的计算方法,并使用三维激光扫描仪和全站仪对某立式油罐进行对比试验。试验结果表明:提出的数据处理方法可以准确计算出立式罐变形检测所需尺寸信息,为立式罐变形检测提供了新的途径。

We proposed a method of vertical tank deformation detection based on three-dimensional laser scanning technology because of the defects of the conventional vertical tank size measuring method, such as labor intensive, low efficiency and low degree of automation. The calculation methods of circular cross-section fitting, inclination, cylindricity, verticality and height of the vertical tank based on three-dimensional laser scanner were analyzed. And using three-dimensional laser scanner and total station, we had compared experiment to a vertical tank. The results show that the proposed methods can accurately calculate the size data of the vertical tank deformation monitoring. It provides a method of data processing of the vertical tank deformation monitoring.
