Abstract
Techniques are provided for facilitating supplemental flat field correction (SFFC) determination for infrared imaging systems and methods. In one example, a method includes capturing, by a focal plane array (FPA) of an imaging system, a first set of images of a first reference object in a scene while the first reference object is at a temperature associated with a second reference object when capturing the first set of images. The method further includes capturing, by the FPA, a second set of images of the second reference object. The method further includes determining SFFC values based on the first set of images and the second set of images. Related devices and systems are also provided.
Claims20
A method comprising:
- capturing, by a focal plane array (FPA) of an imaging system, a first set of images of a first reference object in a scene while the first reference object is at a temperature associated with a second reference object when capturing the first set of images;
- capturing, by the FPA, a second set of images of the second reference object;
- and
- determining supplemental flat field correction (SFFC) values based on the first set of images and the second set of images.
An imaging system comprising:
- a focal plane array (FPA) configured to:
- capture a first set of images of a first reference object in a scene while the first reference object is at a temperature associated with a second reference object when capturing the first set of images;
- and
- capture a second set of images of the second reference object;
- and
- a logic device configured to determine supplemental flat field correction (SFFC) values based on the first set of images and the second set of images.
A method comprising:
- capturing, by a focal plane array (FPA) of an imaging system, a first set of images of a first reference object in a scene;
- capturing, by the FPA, a second set of images of a second reference object while the second reference object is at a temperature associated with the FPA when capturing the second set of images;
- and
- determining supplemental flat field correction (SFFC) values based on the first set of images and the second set of images.
