Monitoring and Detection of Combustible Gas Leakage by Using Infrared Imaging

In this paper, an infrared thermal imaging system is developed for combustible gas leakage monitoring and detection. The related imaging processing and gas leakage detection algorithms are presented. The gas leakage monitoring and detection experiments regarding three different scenes, including two indoor scenes and one outdoor scene, are carried out. The preliminary results show that the proposed imaging system and the algorithms are of detecting the leakage of 1% isobutane at 0.2L/min.
