Embodiment 1

[0045] see figure 2 , is a schematic flowchart of a method for adjusting the depth of field of a binocular AR head-mounted device according to an embodiment of the present invention. The method of this embodiment needs to pre-select a distance mapping relationship δ in the head-mounted device. The distance mapping relationship δ can be a formula or can be It is a correspondence relationship of discrete data, and can also be a projection distance range corresponding to an equivalent center distance. The method for obtaining the distance mapping relationship δ will be described with examples in the following paragraphs. The method for adjusting the depth of field of the binocular AR head-mounted device in the embodiment of the present invention includes the following steps:

[0046] S101: When the user looks at the external environment through the head-mounted device, the head-mounted device obtains the distance Dis from the target object to the human eye; the distance Dis can ...

Embodiment 2

[0070] An embodiment of the present invention provides a binocular AR head-mounted device capable of automatically adjusting the depth of field, including an optical system, an image display source, a distance data acquisition module, and a data processing module. The optical system includes one or several lenses, through which the user can Simultaneously see the real external environment and the virtual information displayed on the image display source; the distance mapping relationship δ is stored in the data processing module, and the distance mapping relationship δ is equivalent to the effective display information of the left and right groups on the image display source of the head-mounted device The mapping relationship between the center distance dn and the distance Ln from the human eye to the virtual image formed by the effective display information through the optical system; the range of the equivalent center distance dn in the distance mapping relationship δ is [0, d...

Abstract

The invention discloses a binocular AR (Augmented Reality) head-mounted device scene depth adjusting method. A mapping relationship between an equivalent center distance dn between a left group of effective display information and a right group of effective display information on an image display source and a distance Ln between a virtual image and a human eye is preset in the head-mounted device; when a user watches the external environment via the head-mounted device, the head-mounted device acquires the distance Dis between a target object and the human eye; Ln is assigned as Dis, an equivalent center distance ds between a left group of effective display information and a right group of effective display information corresponding to the Dis is acquired in a distance mapping relationship delta; and with ds as the equivalent center distance, a to-be-displayed information source image for the virtual information is respectively displayed on the image display source in a left-right mode. Correspondingly, the invention also discloses a binocular AR head-mounted device capable of automatically adjusting the scene depth, virtual information is precisely stacked near a human eye fixation point, the virtual information and the environment are highly integrated, and augmented virtual reality in the true sense is realized.

Description

technical field [0001] The present invention relates to the field of head-mounted display devices, in particular to a binocular AR head-mounted device capable of automatically adjusting the depth of field and a method for adjusting the depth of field. 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 t...
