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.
Claims19
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 an occupant in the vehicle interior in the one or more images;
- utilize the spacing between the plurality of illumination sources to differentiate between the plurality of illumination sources in the vehicle interior to identify the illumination source causing the glare;
- and
- generate and communicate a signal to adjust the illumination source to limit the glare.
6 more elements
An imaging system, comprising:
- a first illumination source configured to illuminate at least a portion of a vehicle interior with a first illumination at a first pulse rate and a second illumination source configured to illuminate at least a portion of a vehicle interior with a second illumination at a second pulse rate;
- a camera configured to capture the first illumination in one or more images of the portion of the vehicle interior with the first pulse rate and capture the second illumination in one or more images of the portion of the vehicle interior with the second pulse rate;
- and
- a controller in communication with the illumination source, the second illumination source, and the camera, the controller configured to:
- receive the one or more images;
- identify a glare associated with an occupant in the vehicle interior in the one or more images;
- and
- generate and communicate a signal to adjust one of the first illumination source and the second illumination source to limit the glare.
5 more elements
An imaging system, comprising:
- a first illumination source in a first operating mode configured to illuminate first region of a vehicle interior with a first illumination and a second illumination source in the first operating mode configured to illuminate a second region of a vehicle interior with a second illumination, wherein the first region is larger than the second region and the second region is contained within the first region;
- a fault detection circuit configured to identify if the first and second illumination sources are operating within a baseline range of the first operating mode;
- a camera configured to capture the first and second illumination in one or more images of the portion of the vehicle interior;
- and
- a controller in communication with the illumination source, the second illumination source, the fault detection circuit and the camera, the controller configured to:
- receive the one or more images;
- receive, from the fault detection circuit, if the first and second illumination sources are operating outside of the baseline range of the first operating mode;
- identify a glare associated with an occupant in the vehicle interior in the one or more images causing the first and second illumination sources to operate outside of the baseline range of the first operating mode;
- and
- generate and communicate a signal to switch the first illumination source to a second operating mode to limit the glare.
