Embodiment 1

[0035] Among the solutions of the existing automotive head-up display systems, most of the automotive head-up display systems with larger viewing angles adopt the method of multi-view, multi-screen, and multi-optical paths (how many imaging positions are required, how many display screens are required), and the combination of imaging devices and images is realized. One-to-one correspondence. Although the above-mentioned technical solution can meet the requirement of simultaneously displaying images in different positions (that is, display image heterogeneity), it greatly increases the complexity and cost of the automobile head-up display system.

[0036] In order to solve the above problems, this embodiment provides a method for realizing the optical engine 10 that includes the close-range image source 140 and the distant-view image source 150: the image segmentation device 110 is arranged on the imaging unit 100, and the imaging unit 100 The unit 100 is divided into a close-r...

Embodiment 2

[0040] This embodiment provides an optical engine 10 and a dual-display car head-up display system, such as figure 2 with image 3 As shown, an optical engine 10 includes an imaging unit 100, an image segmentation device 110 for dividing the imaging unit 100 into a close-range image area 120 and a distant view image area 130, a close-range image source mirror group 210, and a distant view image source Reflector group 220; the close-range image source reflector group 210 faces the near-view image area 120; the long-range image source reflector group 220 faces the long-range image area 130; the present invention also provides a dual-display car head-up The display system includes the above-mentioned optical engine 10 and the concave mirror reflector group 300, the close-range image source reflector group 210 faces the near-view image region 120 and the concave mirror reflector group 300, and transmits the light emitted by the near-view image region 120 The close-range imaging...

Abstract

The invention discloses an implementation method of an optical engine. The implementation method comprises the following steps that: an image segmentation device is arranged on an imaging unit, and the imaging unit is segmented into a close-range image area and a long-range image area; a close-range image source reflector group and a long-range image source reflector group are respectively arranged above or in front of the close-range image area and the long-range image area, a distance between the close-range image area and the close-range image source reflector group is smaller than a distance between the long-range image area and the long-range image source reflector group, so that a close-range imaging light beams and a long-range imaging light beam which are emitted by the close-rangeimage area and the long-range image area are respectively reflected to form a close-range image source and a long-range image source which are in the same direction and have different distances. According to the method of the invention, the imaging unit is divided into the close-range image area and the long-range image area; an image position heterogeneity effect can be obtained without multipleimaging units and light path structures required; the size and cost of the optical engine are decreased; and a head-up display method has higher practical value.

Description

technical field [0001] The invention relates to an automobile head-up display technology, in particular to a method for realizing an optical engine with a dual-display automobile head-up display method, an optical engine and a dual-display automobile head-up display system. Background technique [0002] Car head-up display technology is an important part of the intelligent networked car that is being vigorously developed at home and abroad. Through the application and promotion of the car head-up display (HUD) system on high-end luxury brand cars such as BMW and Mercedes-Benz in the early stage, more and more car manufacturers And users realize the importance of the car's head-up display technology for safe driving, and realize that the driver can obtain important information such as vehicle speed, navigation, road conditions, and vehicle distance without leaving the road. The unique display position of the car head-up display system and the floating transparent display effe...
