Abstract:
A gas concentration-length quantification method may include: acquiring a multi-spectral image of detected radiance including a plurality of pixels using a multi-spectral optical gas imaging camera; estimating a background radiance for at least one of the pixels; calculating a gas concentration-length for the at least one of the pixels based on the detected radiance and the estimated background radiance; and triggering an alert when each alert condition in a list of alert conditions is satisfied. A multi-spectral configuration of the camera may include a reference band that is outside an absorption window of a target gas and an active band that includes at least a portion of the absorption window. Estimating the background radiance may include determining a model relating a detected radiance of the active band to a detected radiance of the reference band and using the model to estimate the background radiance for the active band.

Claim (Index 18):
A non-transitory computer readable medium (CRM) storing computer readable program code embodied therein that:\n reads an image comprising a plurality of pixels; estimates a background radiance for at least one of the plurality of pixels; calculates a gas concentration-length for the at least one of the plurality of pixels based on the image and the background radiance; and triggers an alert when the gas concentration-length for at least one pixel exceeds a gas threshold level, wherein a multi-spectral configuration of the multi-spectral OGI camera includes a reference band that is outside an absorption window of a target gas and an active band that includes at least a portion of the absorption window of the target gas, and wherein estimating the background radiance comprises:\n determining a model relating a detected radiance of the active band to a detected radiance of the reference band, and \n using the model as a calibration model to estimate the background radiance for the active band with or without the presence of a target gas.
