Abstract
Various techniques are disclosed to provide a quantification of a gas leak based on an image of a gas plume generated by the leak. An image location that corresponds to the origin of the gas leak is determined. An exit border is disposed on the image based on the image location that corresponds to the origin of the gas leak. A gas leak rate is computed based at least on gas concentration values of the pixels that overlap the exit border.
Claims20
A gas quantification system, comprising:
- a non-transitory memory;
- and
- a logic device coupled to the non-transitory memory, wherein the logic device is configured to read instructions from the non-transitory memory to cause the gas quantification system to perform operations comprising:
- obtaining an image of a gas plume of a gas leak within a scene, wherein each pixel within the image indicates a gas concentration value corresponding to an area within the scene;
- determining a location on the image corresponding to an origin of the gas leak;
- disposing an exit border on the image based on the location corresponding to the origin of the gas leak, wherein the exit border comprises an arc that extends across at least a cross section of the gas plume where changes in gas concentration values are substantially linear;
- and
- computing a gas leak rate for the gas leak based at least on first gas concentration values of first pixels overlapping the exit border.

A method of quantifying gas, comprising:
- obtaining, from an infrared (IR) camera, an image of a gas plume of a gas leak within a scene, wherein each pixel within the image indicates a gas concentration value corresponding to an area within the scene;
- determining a location on the image corresponding to an origin of the gas leak;
- disposing an exit border on the image based on the location corresponding to the origin of the gas leak, wherein the exit border comprises an arc that extends across at least a cross section of the gas plume where changes in gas concentration values are substantially linear;
- and
- computing a gas leak rate for the gas leak based at least on first gas concentration values of first pixels overlapping the exit border.
