A head-up display device

Abstract

The invention discloses a head-up display device, comprising: a host, used to send an image signal to a display device; a display device arranged on one side of the host, used to display the image signal; A curved semi-transparent reflective screen set at a position is used to receive the image displayed by the display device, and display the image on the other side through the semi-transparent reflective screen on one side of the host; and the semi-transparent reflective screen is also used Therefore, the image is displayed after deghosting; the voice interaction unit pre-installed in the host and the driver detection device installed in the host. The invention provides an intelligent vehicle-mounted device that supports full voice interaction, real-time monitoring and early warning of the driver, and has good display effect. The invention effectively solves the deficiencies in the prior art, such as the lack of voice interactive operation of the head-up display device, inconvenient placement in the car, lack of special emotion analysis for driving, and the like.

Description

technical field [0001] The invention relates to a vehicle-mounted intelligent device, in particular to a head-up display device. Background technique [0002] HUD (Head Up Display) is a flight aid commonly used in aircraft. Heads up means that the pilot does not need to look down to see the important information he needs. [0003] At present, the head-up display HUD also has the following defects: [0004] 1. Most of them can only display information such as vehicle speed and fuel level, and have no operating functions at all. [0005] 2. Insufficient in the principle of realization, generally by projecting vehicle-related information on glass and coated lenses (optical mirrors), and then balancing and reflecting it into the driver's eyes. [0006] 3. In terms of display methods, a projector based on the LED principle is generally used for projection, and the image is displayed on the imaging film, and the driver can see the relevant information of the vehicle through the...

Problems solved by technology

[0004] 1. Most of them can only display information such as vehicle speed and fuel level, and have no operating functions at all

[0005] 2. Insufficient in the implementation principle, generally by projecting vehicle-related information on glass and coated lenses (optical mirrors), and then balancing and reflecting into the driver's eyes

In addition, the use of a projector will be limited by the imaging distance, which will affect the overall appearance of the HUD device

[0007] 4. The information displayed on the HUD head-up display may be unclear, especially in the case of strong light in front, and there may be ghosting of the image, which will affect the driver's driving

[0008] 5. The imaging distance of the HUD is not far enough to be placed in the car, and the focal length does not match the driving scene, which cannot solve the problem of far-near fusion of the road surface and the instrument panel
