Embodiment Construction

[0021] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0022] like Figure 1-3 As shown, a reentrant AR-HUD dual-screen imaging system of the present invention includes a first reflector 5, a second reflector 6, a transmission group 7 and a display screen, and the imaging light emitted by the display screen passes through the transmission group. The aberration is optimized, and the optical path is compressed or stretched, transmitted to the second reflector 6, and the second reflector 6 reflects the imaging light to the first reflector 5, and the first reflector 5 reflects the imaging light to the windshield imaging.

[0023] In this embodiment, the display sc...

Abstract

The invention discloses a turn-back type AR-HUD far and near view double-screen imaging system. The system comprises a first reflector, a second reflector, a transmission group and a display screen, imaging light emitted by the display screen is subjected to aberration optimization through the transmission group, an optical path is compressed or stretched and transmitted to the second reflector, the second reflector reflects the imaging light to the first reflector, and the first reflector reflects the imaging light to windshield glass for imaging. According to the system, the transmission group is added into a reflection type HUD system to compress or stretch a long-range or close-range light path displayed by double screens, and the distance feeling of long-range and close-range imagingis satisfied under the condition of sharing the first reflector, the second reflector and the display screen at the same time; the transmission group itself ensures good aberration correction, and cooperates with the first reflector and the second reflector to perform aberration correction, thereby ensuring index requirements of a display image; the complexity of structural arrangement can be greatly reduced, the stability of the system is improved, and the space volume of the AR-HUD is compressed; and the feasibility of whole vehicle assembly is improved.

Description

technical field [0001] The invention relates to the technical field of AR-HUD, in particular to a switchback type AR-HUD dual-screen imaging system for far and near views. Background technique [0002] At this stage, W-HUD has been widely used in all kinds of cars, displaying the vehicle information required by the driver on the windshield, which can avoid the unsafe factors caused by the driver frequently looking down at the vehicle information. [0003] The AR-HUD dual-screen display can not only display the vehicle information needed by the driver on the windshield glass, but also realize the auxiliary driving function during the driving process and increase the information feedback between the driving environment and the vehicle. [0004] The current AR-HUD solutions all use the reflective principle to realize dual-screen display. In order to realize the distinction between the distant view and the near view, the optical path needs to be designed with different lengths. ...
