Abstract
A method is provided that includes projecting a hybrid headlight frame into a scene in front of a vehicle by a digital micromirror device (DMD) headlight, wherein the hybrid headlight frame includes a structured light pattern and a high beam headlight pattern, and capturing an image of the scene by a camera included in the vehicle while the structured light pattern is projected.
Claims18
A method comprising:
- projecting a hybrid headlight frame into a scene in front of a vehicle by a digital micromirror device (DMD) headlight, wherein the hybrid headlight frame comprises a structured light pattern and a high beam headlight pattern;
- and
- capturing an image of the scene by a camera comprised in the vehicle while the structured light pattern is projected.
A method comprising:
- generating a high beam headlight frame by a first processor comprised in a digital micromirror device (DMD) headlight control unit, wherein the high beam headlight frame comprises a high beam headlight pattern;
- transmitting, by the first processor, the high beam headlight frame and a bit plane of a structured light pattern to a DMD controller comprised in the DMD headlight control unit;
- and
- generating, by the DMD controller, bit planes of a hybrid headlight frame, wherein the bit planes comprise the bit plane of the structured light pattern and bit planes of the high beam headlight pattern.
1 more element
A vehicle comprising:
- a headlight comprising a digital micromirror device (DMD);
- a DMD headlight control unit coupled to the DMD, the DMD headlight control unit configured to cause the DMD to project a hybrid headlight frame, wherein the hybrid headlight frame comprises a structured light pattern and a high beam headlight pattern;
- a camera;
- and
- an advanced driver assistance systems (ADAS) electronic control unit (ECU) coupled to the camera and to the DMD headlight control unit, the ADAS ECU configured to trigger the camera to capture an image of the structured light pattern.
