Alignment of visible light sources based on thermal images
First Claim
Patent Images
1. A system comprising:
- an infrared imaging module comprising a focal plane array (FPA) configured to capture an unblurred thermal image of a scene and an intentionally blurred image of the scene;
a processor configured to determine a plurality of non-uniform correction (NUC) terms based on the intentionally blurred thermal image, apply the NUC terms to the unblurred thermal image to remove noise form the unblurred thermal image, and generate alignment guide information from the unblurred thermal image; and
a visible light source configured to be selectively directed based on the alignment guide information to substantially align the visible light source with a desired subject and project a visible light beam substantially on the subject.

Abstract
Various techniques are disclosed for providing systems for providing alignment guide information to selectively direct a visible light source to substantially align the visible light source with a desired subject and to project a visible light beam substantially on the desired subject. For example, a system may include a small form factor infrared imaging module to capture thermal images of a scene, which may be received by a processor to generate alignment guide information such as a user-viewable image of the scene, a user-viewable cue, and a framing reticle. In another example, such a system may be implemented as a camera. In yet another example, such a system may be implemented as a spotlight.

11. A method of operating a system, the method comprising:
-
capturing an unblurred thermal image of a scene and an intentionally blurred image of the scene at a focal plane array (FPA) of an infrared imaging module; determining a plurality of non-uniform correction (NUC) terms based on the intentionally blurred thermal image; applying the NUC terms to the unblurred thermal image to remove noise form the unblurred thermal image; generating, from the unblurred thermal image, alignment guide information; receiving a force to selectively direct a visible light source to substantially align the visible light source with a desired subject based on the alignment guide information; and projecting a visible light beam from the visible light source substantially on the subject while the visible light source is aligned based on the alignment guide information. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
