A VOCs Gas Detection Algorithm Based On Infrared Thermal Imaging

For the current VOCs gas leakage detection and localization algorithm based on infrared thermal imaging, the problems of missed detection and high false positive rate are high. This paper presents an algorithm for multi-feature VOCs gas leak detection based on infrared thermal imaging . The algorithm uses infrared thermal imager to obtain infrared temperature data, converts it `identification is based on various characteristics such as the change of the area of the connected domain, the irregularity and the direction of motion, so as to obtain the exact position of the gas leakage region. The experimental results show that the proposed algorithm can detect VOCs gas leakage in time, with high robustness and strong anti-interference ability, and can accurately locate the VOCs gas leakage area.
