Abstract

The invention relates to an overlapped method for a virtual object in AR glasses. The method comprises that the AR glasses are fixedly arranged in a set position in a practical scene, and a practical marker with multiple scales is placed in front of the AR glasses; panoramic scanning is carried out on the practical scene to obtain a virtual scene corresponding to the practical scene; the virtual scene is introduced into a development device, and a video scene shot by the AR glasses is uploaded to the development device; after that the development device enters a debugging mode, the virtual scene and the video scene are displayed in the same interface, and virtual scales in the virtual scene are adjusted to be overlapped with shooting scales in the video scene; and the virtual object is overlapped to a target position in the virtual scene, an overlap range parameter in overlapping the virtual object in the virtual scene is obtained, and the virtual object and the overlap range parameter are sent to the AR glasses. Thus, the practical scene corresponding to the video scene can be restored highly effectively, and the virtual scene displayed by the AR glasses has a better display effect.

Description

technical field

[0001] The present invention relates to the technical field of virtual display glasses, in particular to a method for superimposing virtual objects in AR glasses. Background technique

[0002] AR (augmented reality technology) glasses such as HoloLens glasses are smart display devices for displaying virtual reality scenes. If it is necessary to improve the augmented reality function of AR glasses such as HoloLens glasses, it is necessary to accurately obtain real-world information (such as the actual scene information corresponding to the virtual scene). In the process of displaying the corresponding virtual scene, AR glasses need to rely on the corresponding SLAM (Simultaneous Localization and Mapping) system. Taking HoloLens glasses as an example, HoloLens glasses rely on two cameras on the left and right sides, covering a horizontal viewing angle and a vertical viewing angle of 120 degrees. These cameras can obtain depth maps from different angles in rea...

Embodiment Construction

[0013] The specific implementation of the method for superimposing virtual objects in AR glasses of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] refer to figure 1 , figure 1 Shown is a flow chart of a method for superimposing virtual objects in AR glasses in an embodiment, including the following steps:

[0015] S10, fixing the AR glasses at a set position in the actual scene, and placing actual markers marked with multiple scales in front of the AR glasses;

[0016] The above steps can be fixed at the set position in the actual scene through the bracket, and the above set position can be a certain side or above a certain corner in the actual scene; the AR glasses are fixed at the set position, and the AR glasses carried by themselves The camera can capture most of the space of the actual scene.

[0017] The above actual markers can be as figure 2 As shown in the cube, multiple scales can be marked on each...
