针对储罐沉降问题,提出一种基于汉宁窗变密度条纹和二维视觉的储罐沉降测量系统.将设计的汉宁窗变密度条纹附于被测储罐的表面,在一定距离处通过远焦成像相机对表面的条纹进行实时采集,再通过特定的图像处理算法对图像进行处理以提取储罐的沉降位移.通过SOLIDWORKS三维建模、运动仿真和图像成像模块模拟了不同条件下储罐沉降的图像序列,对主要的测量性能影响因素、测量可行性和准确性进行了模拟分析.搭建了储罐沉降模拟实验测量系统,对系统的测量性能进行了实验分析.结果表明,本测量方法可实现储罐沉降位移的实时监测,在7.5 m距离外沉降位移测量精度优于10 μm.
A novel measurement system based on Hanning-window-changing density fringes and two-dimensional vision was proposed for monitoring the tank settlement.The artificial Hanning-window-changing density fringes were attached to the surface of the tested storage tank,and the surface fringes were collected in real time by a far-focus imaging camera at a certain distance,and then the images were processed by a specific image processing algorithm to extract the settlement displacement of the storage tank.The image sequences of tank settlement under different conditions were simulated by SOLIDWORKS 3D modeling,motion simulation and image imaging module,and the main measurement performance influencing factors,measurement feasibility and accuracy were simulated and analyzed.The simulated experimental measurement system of tank settlement was constructed,and its measurement performance was analyzed experimentally.The results show that the proposed system can realize real-time monitoring of the tank settlement displacement,and the measurement accuracy can be better than 10 μm at a distance of 7.5 m.
