Binocular AR (Augmented Reality) head-mounted display device and information display method thereof

Abstract

The invention discloses a binocular AR head-mounted display device and an information display method thereof. The adjustment of the projection distance is realized by zooming a liquid lens, and the adjustment of the projection angle is realized by calculating the relative offset of effective display information on an image display source. Finally, the virtual information can be accurately superimposed on the spatial position of the target object, so that the virtual information can be highly integrated with the environment, and the real augmented virtual reality can be realized. The scheme of the present invention is simple. On the premise that the distance mapping relationship η is preset in the head-mounted display device, it is only necessary to obtain the spatial position data of the target object relative to the user, and the spatial position data can be measured in various ways. distance, depth of field camera, etc., with mature hardware technology, high reliability and low cost.

Description

technical field [0001] The present invention relates to the technical field of head-mounted displays, in particular to a binocular AR head-mounted display device and an information display method for the binocular AR head-mounted display device. Background technique [0002] With the rise of wearable devices, various head-mounted display devices have become the research and development hotspots of major giant companies, gradually entering people's field of vision. Head-mounted display devices are the best application environment for Augmented Reality Technology (AR for short), which can present virtual information in the real environment through the head-mounted device window. However, most existing AR head-mounted display devices currently have Information superposition only considers the correlation with the X and Y axis coordinates of the target position, but does not calculate the depth information of the target, so that the virtual information floats in front of the hum...

Head-mounted display devices are the best application environment for Augmented Reality Technology (AR for short), which can present virtual information in the real environment through the head-mounted device window. However, most existing AR head-mounted display devices currently have Information superposition only considers the correlation with the X and Y axis coordinates of the target position, but does not calculate the depth information of the target, making the virtual information float in front of the human eye, the degree of integration with the environment is not high, and the user experience is not good
