Abstract
In a leaked gas detection device and a leaked gas detection method according to the present invention, a gas cloud image area of a gas cloud formed with a leaked gas is extracted on the basis of an infrared image of a target area, a gas temperature of the gas cloud is acquired, a concentration-thickness product of the gas cloud is obtained, and a reliability degree that is an index representing the degree of reliability with respect to the obtained concentration-thickness product of the gas cloud is obtained on the basis of a background temperature in the gas cloud image area and the gas temperature of the gas cloud.
Claims14
A leaked gas detection device comprising:
- an infrared image acquisitor that acquires an infrared image of a target area;
- a hardware processor that extracts a gas cloud image area of a gas cloud formed with a leaked gas on the basis of the infrared image of the target area acquired in the infrared image acquisitor;
- and
- a gas cloud temperature acquisitor that acquires a gas temperature of the gas cloud;
- the hardware processor obtaining a concentration-thickness product of the gas cloud, and obtaining a reliability degree that is an index representing the degree of reliability with respect to the concentration-thickness product of the gas cloud obtained in the hardware processor on the basis of a background temperature in the gas cloud image area extracted in the hardware processor and the gas temperature acquired in the gas cloud temperature acquisitor.
