Title:
AUGMENTED REALITY HEAD-UP DISPLAY DEVICE AND DOUBLE-IMAGE ELIMINATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/100518
Kind Code:
A1
Abstract:
An augmented reality head-up display device and a double-image elimination method. The device comprises a reflector group and a display module. The display module is used to generate a first image source and a second image source. The reflector group is used to reflect the first image source onto a windshield to form a first image and to reflect the second image source onto the windshield to form a second image. The first image and the second image formed by the reflector group meet the following preset conditions: determining whether a projection distance of a meridional image of the first image and that of a meridional image of the second image are equal (S102); and adjusting the astigmatic aberration absolute values of the first image and the second image if the projection distances are equal (S104). The invention solves the technical problem that double images on a windshield head-up display device cannot be eliminated.
