Abstract
A head up display arrangement is for a motor vehicle having a human occupant. A light source emits a light field. An infrared camera detects infrared energy. A combiner is positioned and configured to reflect the light field such that the light field can be viewed by the human occupant as a virtual image. The combiner has a region configured to reflect infra-red energy emitted by a face of the occupant such that the infrared energy is received by the infrared camera.
Claims16
A head up display arrangement for a motor vehicle having a human occupant, comprising:
- a light source configured to emit a light field;
- an infrared camera configured to detect infrared energy;
- and
- a combiner positioned and configured to reflect the light field such that the light field can be viewed by the human occupant as a virtual image, the combiner having a region configured to reflect infrared energy emitted by a face of the occupant such that the infrared energy is received by the infrared camera, wherein the combiner includes a first part and a second part, at least one infrared-reflecting element being disposed between the first part and the second part, wherein the infrared-reflecting element has an oval shape.
A head up display arrangement for a motor vehicle having a human occupant, comprising:
- a light source configured to emit a light field;
- an infrared camera configured to detect infrared energy;
- and
- a combiner positioned and configured to reflect the light field such that the light field can be viewed by the human occupant as a virtual image, the combiner having a region configured to reflect infrared energy emitted by a face of the occupant such that the infrared energy is received by the infrared camera, wherein the combiner includes a first part and a second part, at least one infrared-reflecting element being disposed between the first part and the second part, wherein the at least one infrared-reflecting element comprises a plurality of substantially identically-shaped infrared-reflecting elements.
A head up display method for a motor vehicle having a human occupant, said method comprising:
- emitting a light field;
- providing an infrared camera to detect infrared energy;
- positioning a combiner to reflect the light field such that the light field can be viewed by the human occupant as a virtual image wherein the combiner includes a first part and a second part, at least one infrared-reflecting element being disposed between the first part and the second part, wherein the infrared-reflecting element has an oval shape;
- and
- using a region of the combiner to reflect infrared energy emitted by a face of the occupant such that the infrared energy is received by the infrared camera.
