Problems solved by technology

Since the transmission of the image mainly depends on the optical relay system and the optical path formed by the windshield, and for the windshield, the curvature of the windshield used by different brands and different models is different. In order to display images clearly, the HUD system needs to adapt windshields

Embodiment Construction

[0028] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0029] The embodiment of the present invention provides a head-up display device. Compared with the existing head-up display system, the HUD system mainly adds a device for autonomous detection and adjustment of the display image aberration, while for the existing HUD system, such as figure 1 As shown, although the optical relay system adopts an off-axis reflective system, there are also monochromatic aberrations such as spherical aberration, c...

Abstract

The invention discloses a head up display (HUD) device and a display image correction method, and relates to the technical field of computers, mainly aiming at improving the versatility of an HUD system by dynamically adjusting the suitability between an optical relay system in the HUD system and windshield of a vehicle by means of an aberration adjustment device. The HUD device is mainly characterized by comprising an image source, an optical transmission unit, a sensor and a correcting circuit, wherein the image source is a light source used for emitting display images; the optical transmission unit is used for transmitting detection light containing imaging distortion information; the sensor is used for receiving the detection light and converting the detection light into a wavefront error image; the correcting circuit is used for receiving the wavefront error image and correcting the display images emitted by the image source according to the wavefront error image.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted display devices, in particular to a head-up display device and a display image correction method. Background technique [0002] Head up display (head up display, HUD), also known as head-up display, was first used in the field of fighter jets based on radar aiming and optical aiming. After General Motors launched the first head-up display system in the 1990s, it has gradually been widely used in the automotive field. HUD projects the dashboard information and surrounding environment information required by the driver to the appropriate position of the windshield in front of the driver, so as to ensure that the driver can judge the vehicle speed, fuel level and other information without bowing his head, and avoid accidents caused by frequent head up and down. potential safety hazards and reduce driver safety risks. [0003] At present, the vehicle-mounted HUD system mainly includes four p...
