Abstract
An imaging system includes an illumination source configured to illuminate at least a portion of a vehicle interior. A camera is configured to capture one or more images of the portion of the vehicle interior. A controller is in communication with the illumination source and the camera. The controller is configured to receive the one or more images, identify a glare associated with an occupant of the vehicle interior in the one or more images, and generate and communicate a signal to adjust the illumination source to limit the glare.
Claims20
An imaging system, comprising:
- a plurality of illumination sources spaced from one another and configured to illuminate at least a portion of a vehicle interior from different angles;
- a camera configured to capture one or more images of the portion of the vehicle interior;
- and
- a controller in communication with the illumination source and the camera, the controller configured to:
- receive the one or more images;
- identify a glare associated with a surface of an occupant in the vehicle interior in the one or more images;
- identify an angle of incidence to identify an illumination source of the plurality of illumination sources responsible for the glare;
- and
- generate and communicate a signal to adjust the illumination source responsible for the glare to limit the glare.
An imaging system, comprising:
- a plurality of illumination sources spaced from one another and configured to illuminate at least a portion of a vehicle interior from different angles, wherein the first illumination source projects a first illumination and the second illumination source projects a second illumination in a different wavelength than the first illumination;
- a camera configured to capture one or more images of the portion of the vehicle interior, the camera including a color filter to capture the one or more images of both the first and second illuminations;
- and
- a controller in communication with the illumination source and the camera, the controller configured to:
- receive the one or more images;
- identify a glare associated with a surface of an occupant in the vehicle interior in the one or more images;
- identify a wavelength responsible for the glare;
- and
- generate and communicate a signal to adjust the illumination source responsible for the glare to limit the glare.
An imaging system, comprising:
- a plurality of illumination sources spaced from one another and configured to illuminate at least a portion of a vehicle interior from different angles;
- a camera configured to capture one or more images of the portion of the vehicle interior;
- and
- a controller in communication with the illumination source and the camera, the controller configured to:
- receive the one or more images;
- identify an occupant's eyes;
- identify a glare associated with the occupant's eyes in the one or more images;
- identify a shape of the glare and a projection angle of the glare to identify an illumination source of the plurality of illumination sources responsible for the glare;
- and
- generate and communicate a signal to adjust the illumination source responsible for the glare to limit the glare.
