Abstract
The present invention relates to a lighting system 200 of an automotive vehicle comprising: —an image capture device (205) configured to acquire an image (I) of a road (R) of travel of the vehicle, said road (R) comprising lanes marked on the road (110); —a lighting module (215) configured to project road markings on the road (120); wherein said lighting system (200) is configured to filter the projected road markings (120) on the road compared to the lanes marked (110) on the road.
Claims25
A lighting system of an automotive vehicle, the lighting system comprising:
- a lighting device that includes a light source, the lighting device being configured to project road markings on a road of travel of the vehicle using a pulse light beam;
- and
- image capture circuitry configured to
- acquire an image of the road of travel of the vehicle, the road including lanes marked on the road, and the image including the projected markings on the road and the lanes marked on the road,
- identify within said image the projected road markings on the road corresponding to the pulse light beam,
- differentiate pulsed light zones corresponding to the projected road markings on the road from non-pulsed zones corresponding to the lanes marked on the road, and
- remove the projected road markings on the road from the image.
A method comprising:
- projecting, by a lighting device that includes a light source, road markings on a road of travel of a vehicle using a pulse light beam;
- acquiring, by image capture circuitry, an image of the road of travel of the vehicle, the road including lanes marked on the road, and the image including the projected markings on the road and the lanes marked on the road;
- identifying, by the image capture circuitry, within said image the projected road markings on the road corresponding to the pulse light beam;
- differentiating, by the image capture circuitry, pulsed light zones corresponding to the projected road markings on the road from non-pulsed zones corresponding to the lanes marked on the road;
- and
- removing, by the image capture circuitry, the projected road markings on the road from the image.
A method for synchronizing an operation of a lighting device, which includes a light source, of a vehicle with image capture circuitry, the method comprising:
- acquiring, by the image capture circuitry, an image of a road of travel of the vehicle;
- projecting, by the lighting device, road markings on the road using a pulse light beam;
- identifying, by the image capture circuitry, within said image the projected road markings on the road corresponding to the pulse light beam;
- differentiating, by the image capture circuitry, pulsed light zones corresponding to the projected road markings on the road from non-pulsed zones corresponding to lanes marked on the road;
- removing, by the image capture circuitry, the projected road markings on the road from the image;
- deactivating, by control circuitry, the lighting device and simultaneously activating the image capture circuitry on a first mode;
- and
- activating, by control circuitry, the lighting device and simultaneously deactivating the image capture circuitry on a second mode.
