基于红外光谱成像的危险气体泄漏检测技术综述.

Dangerous gas detection technology, which plays an important role in industrial production, is one of the necessary guarantees for the safety of petrochemical and other enterprises. Firstly, the advantages and disadvantages of existing hazardous gas detection technologies were compared, clarifying that infrared imaging technology based on molecular absorption spectroscopy had the advantages of being suitable for long-range monitoring and low maintenance costs in hazardous gas detection thus was the ideal form of wide area surveillance. Secondly, the detection principle and hardware composition of infrared imaging technology were introduced. Next, some related researches on leakage image visualization and gas concentration analysis were enumerated. Then, the automatic gas leak detection algorithms based on infrared image analysis technology were analyzed, and the development status and problems of traditional image-processing-based methods and deep learning algorithms were analyzed in depth respectively. Finally, the technical difficulties and development trends of infrared spectral imaging were summarized. [ABSTRACT FROM AUTHOR]
