AR-HUD optical path system of overturning regulation

Abstract

The present invention relates to the technical field of the HUD, especially to an AR-HUD (Augmented Reality-Head Up Display) optical path system of overturning regulation. The system comprises: an image source display module configured to generate an AR-HUD optical path, an optical path regulation module and a windshield. The optical path regulation module is provided with a first reflector and asecond reflector. The optical path regulation module employs an overturning second reflector to greatly reduce the usage area required by lenses, the image source display module comprises a reflectorto turn back a projection optical path to allow the whole optical path to be more compact so as to greatly reduce the size of the AR-HUD. The image source display module employs a projection display mode, namely the image of a projection calender is projected on a diffusion plate for display, the diffusion plate is heat-resistant so as to effectively avoid that the sunshine focusing damages imagesource parts. When the optical path system is used, drivers can select proper positions for watching projection virtual images according to the heights themselves so that the AR-HUD optical path system of overturning regulation has good augmented reality aided driving experience.

Description

technical field [0001] The invention relates to the technical field of HUD, in particular to a flip-adjustable AR-HUD optical path system. Background technique [0002] At present, AR-HUD (Augmented Reality-Head Up Display) combines augmented reality with a head-up display, and is mainly used in the assisted driving process of a car. From a software point of view, in order to reduce the difficulty of the algorithm for the fusion of real and virtual images, the position of the projected image is required to remain unchanged, so the lens is not allowed to flip (flipping will cause the movement of the image plane), because it needs to meet different drivers. The height requirement of the AR-HUD directly leads to an increase in the area required for the lens, which is also one of the main reasons for the excessive size of the AR-HUD. Moreover, the lens of AR-HUD is larger than that of ordinary HUD, and the projection distance is far, resulting in more sunlight being collected b...

Problems solved by technology

[0004] The invention provides a reversible adjustable AR-HUD optical path system, which solves the technical problem that the non-reversible design of the lens in the existing AR-HUD optical path system leads to the excessive volume of the AR-HUD and the large internal lens of the AR-HUD Easy to damage image source parts due to sunlight gathering
