Image processing device for gas detection, image processing method for gas detection, image processing program for gas detection, computer-readable recording medium having image processing program for gas detection recorded thereon, and gas detection system

A gas-detection image-processing method comprising:

• calculating identification values each corresponding to a respective one of a plurality of pixels constituting an infrared image of a monitoring target, the identification values being identification values for identifying, from among the plurality of pixels constituting the infrared image, a pixel constituting a gas image and a pixel constituting a non-gas image;
• and
• based on the identification values, identifying, in a monitoring image that is generated by using the infrared image, a pixel constituting the gas image and a pixel constituting the non-gas image.

A non-transitory recording medium storing a computer readable gas-detection image-processing program thereon, the program being executable by a computer to control the computer to execute processes comprising:

• calculating identification values each corresponding to a respective one of a plurality of pixels constituting an infrared image of a monitoring target, the identification values being identification values for identifying, from among the plurality of pixels constituting the infrared image, a pixel constituting a gas image and a pixel constituting a non-gas image;
• and
• based on the identification values, identifying, in a monitoring image that is generated by using the infrared image, a pixel constituting the gas image and a pixel constituting the non-gas image.

A gas detection system comprising:

• an infrared camera that takes images of a monitoring-target area;
• and
• a hardware processor that calculates identification values each corresponding to a respective one of a plurality of pixels constituting an image of the monitoring-target area taken by the infrared camera, the identification values being identification values for identifying, from among the plurality of pixels constituting the image of the monitoring-target area taken by the infrared camera, a pixel constituting a gas image and a pixel constituting a non-gas image.
