Abstract

Non-contact sludge measurement methods for storage tanks can address the challenge of measuring the volume of sedimented sludge during long-term storage. While infrared thermography technology can address the issue of liquid level detection, its measurement accuracy for the undulating interface of sludge is insufficient. This study designed and constructed experimental setups for measuring sludge in storage tanks. In this study, infrared images taken by an infrared camera were used to record the temperature distribution of the outer wall of the storage tank. The threshold segmentation method is used to determine the accurate sludge boundary line in image processing. Finally, the Three-Dimensional Tank Residue Recovery Algorithm (3D-TRRA) was applied to fit the 3D distribution of the sludge and calculate accurate sludge volumes. The results indicate that the best segmentation is achieved with a threshold of 170. The measurement error for sludge volume is less than 5%. Accurate visual positioning and recognition of sludge are achieved.

基于非接触式红外热成像技术的实验室原油储罐内部存储测量

用于储罐的非接触式污泥测量方法可以解决在长期储存过程中测量沉积污泥体积的难题。虽然红外热成像技术可以解决液位检测问题，但其对污泥起伏界面的测量精度不够。本研究设计并构建了用于测量储罐中污泥的实验装置。本研究使用红外相机拍摄的红外图像来记录储罐外壁的温度分布。在图像处理中，采用阈值分割法确定准确的污泥边界线。最后，应用三维储罐残留物复原算法（3D-TRA）拟合污泥的三维分布，计算出准确的污泥体积。结果表明，阈值为 170 时的分割效果最佳。污泥体积的测量误差小于 5%。实现了污泥的精确视觉定位和识别。

期刊介绍： The Journal covers the entire field of infrared physics and technology: theory, experiment, application, devices and instrumentation. Infrared'' is defined as covering the near, mid and far infrared (terahertz) regions from 0.75um (750nm) to 1mm (300GHz.) Submissions in the 300GHz to 100GHz region may be accepted at the editors discretion if their content is relevant to shorter wavelengths. Submissions must be primarily concerned with and directly relevant to this spectral region. Its core topics can be summarized as the generation, propagation and detection, of infrared radiation; the associated optics, materials and devices; and its use in all fields of science, industry, engineering and medicine. Infrared techniques occur in many different fields, notably spectroscopy and interferometry; material characterization and processing; atmospheric physics, astronomy and space research. Scientific aspects include lasers, quantum optics, quantum electronics, image processing and semiconductor physics. Some important applications are medical diagnostics and treatment, industrial inspection and environmental monitoring.
