Abstract

The invention relates to the field of automobile electronics, and discloses an augmented virtual reality projection method and system based on sight tracking. The augmented virtual reality projectionmethod based on sight tracking is applied to an automobile, the automobile adopts an AR-HUD technology, and the method comprises; acquiring a video image in the automobile; detecting a face image of atarget user in the video image; determining a reference position coordinate and a following position coordinate according to the face image; calculating an included angle between the sight line of the target user and the horizontal direction of the automobile according to the reference position coordinate and the following position coordinate; and adjusting the projection angle of the virtual camera corresponding to the AR scene according to the included angle. According to the embodiment of the invention, the augmented virtual reality projection effect is improved.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to an augmented virtual reality projection method and system based on line-of-sight tracking. Background technique [0002] AR-HUD technology is to superimpose virtual display information on top of the real world to enhance the driver's understanding of the current situation and improve their driving experience. Display information includes navigation maps, vehicle information, pedestrian information, lane line information, weather information, building information, etc. Material information, performance information, application information, etc. However, the projection positions of most of the displayed information are fixed, and cannot be dynamically projected in real-time at a position that the driver can easily notice at present, thereby reducing the projection effect of augmented virtual reality.
