英文摘要： With the rapid development of industrial automation and progress of science and technology, the requirements of leak detection on industrial equipment are more and more important. There are some problems on the existing equipment of leak detection and location, such as too low detection efficiency and relying on imports. There are some advantages on detection by using infrared detection technology such as quick response, non-contact measurement and wide temperature rage. Therefore, it will be obtained better detection results by designing a reasonable method on leak detecting and location via infrared image technology. This project studies the method of leak detection and location based on infrared image technology. Firstly, a kind of gas leak heat transfer model is set up during the charging and discharging process by analyzing the temperature field of infrared image. Secondly, on the basis of systematic research on adaptive gas leak detection and location technology for a single frame infrared image, a gas leak detection method is presented via pipeline filter approach with analysis and study on the infrared image sequence. Lastly, an experimental platform is set up with infrared image acquisition and processing, and the developed techniques in this project will be verified by this experimental platform. The research results are expected to offer solid theoretical foundation and technical basis for the engineering practice of gas leak detection technology based on infrared image sequence, and further promote the application process of infrared image technology on leak detection for containers.
