Abstract
A head-up display (HUD), includes an imaging unit, an optical element, which is suitable for deflecting the radiation of the imaging unit in the direction of a windshield and thereby irradiating an HUD region of the windshield in order to generate a virtual image, a positioning device, which is suitable for fixing the windshield in a defined arrangement relative to the optical element, and a camera unit, which is suitable for capturing the virtual image through the windshield from different eye positions, wherein the optical element is configured such that the entire virtual image lies within the depth of field range of the camera unit.
Claims20
A testing device for a head-up display, comprising:
- an imaging unit,
- an optical element, which is arranged to deflect a radiation of the imaging unit in a direction of a windshield and thereby irradiate an HUD region of the windshield in order to generate a virtual image,
- a positioning device, which is arranged to fix the windshield in a defined arrangement relative to the optical element, and
- a camera unit, which is arranged to capture the virtual image through the windshield from different eye positions,
- wherein the optical element is configured such that the entire virtual image lies within a depth of field range of the camera unit.
A method for testing a head-up display, comprising:
- positioning a windshield with an HUD region by a positioning device in a defined arrangement relative to an optical element,
- irradiating the optical element by an imaging unit, wherein the radiation is deflected by the optical element in a direction of the windshield, and the HUD region is irradiated, with a virtual image generated thereby,
- capturing the virtual image by a camera unit from different eye positions,
- wherein the optical element is configured such that the entire virtual image lies within a depth of field range of the camera unit.
A method comprising utilizing an optical element for deflecting a radiation of an imaging unit onto an HUD region of a windshield, whose arrangement relative to the optical element is fixed by a positioning device, wherein a virtual image is generated, which is captured from different eye positions through the windshield for testing purposes by a camera unit, wherein the optical element is configured such that the entire virtual image lies within a depth of field range of the camera unit.
