Application of multi-sensor data fusion technology in pipeline nondestructive testing

Pipeline is the most economical and efficient transportation mode of oil and gas. It is very important to ensure the safety and integrity of pipeline. Nondestructive testing of pipeline is a powerful guarantee for the safe and stable operation of oil and gas pipeline. In the data processing of pipeline inspection, the multi-sensor data fusion model with low computational cost and high precision has a broad application prospect in the future pipeline defect identification quantification and contour reconstruction. In this paper, the multi-sensor data fusion technology and its application in the field of pipeline inspection were reviewed, the application of multi-sensor data fusion technology in composite inspection technology, pipeline defect identification and quantification was discussed, and the existing problems and future research directions were analyzed.
