Embodiment Construction

[0048] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0049] Infrared video of petrochemical gas leakage shot in real environment has low resolution and high noise, and the gas leakage and diffusion are not obvious at long imaging distance. However, the general direct detection method on the original infrared video is affected by the inconspicuous infrared gas imaging and the large noise interference, and the detection effect is poor.

[0050] The main technical scheme of the present invention is as follows: obtaining the original infrared video of petrochemical gas leakage, processing the original infrared video using a preset motion amplification method to obtain a target video; extracting the leaked image frames in the target video, based on The leaked image frame establishes a data set; builds an initial petrochemical gas leak detection model, uses the data set...

Abstract

The invention discloses a petrochemical gas leakage detection method, system and device and a storage medium, and relates to the technical field of environment monitoring, and the method comprises the steps: obtaining an original infrared video of petrochemical gas leakage, processing the original infrared video through a preset motion amplification method, and obtaining a target video; extracting a leaked image frame in the target video, and establishing a data set based on the leaked image frame; constructing an initial petrochemical gas leakage detection model, and training the initial petrochemical gas leakage detection model by using the data set to obtain a target petrochemical gas leakage detection model; and obtaining a to-be-detected video subjected to motion amplification processing, inputting the to-be-detected video into the target petrochemical gas leakage detection model to obtain a detection result, and judging whether petrochemical gas leakage exists in the to-be-detected video according to the detection result. The technical effect of improving the petrochemical gas leakage detection accuracy is achieved.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a petrochemical gas leak detection method, system, equipment and storage medium. Background technique [0002] In recent years, with the rapid development of the petrochemical industry, the issue of production safety has become more and more important. The leakage of petrochemical gas is one of the main causes of fire explosion, poisoning and environmental pollution accidents. Petrochemical gases include a wide variety of high-concentration volatile organic compounds (VOCs, Volatile Organic Compounds), which are flammable, explosive, toxic and harmful gases, which bring great harm to the ecological environment and human health. VOCs also contribute to the formation of ozone, a major source of smog and one of the leading causes of respiratory illnesses in areas near urban petrochemical plants. [0003] The common method of collecting gas leakage in the outdoor e...
