An Augmented Reality Multiplayer Sharing Interaction Method for Plane Recognition Patterns

Abstract

The invention relates to the technical field of augmented reality, in particular to a multi-person sharing interaction method for augmented reality in a plane recognition mode. By distributing two or more AR running terminals at equal intervals around the plane pattern, and the angle range of the plane angle formed by the connection line between the camera of the AR running terminal and the center point of the plane pattern and the horizontal plane is 20°-30°, The camera of the AR running terminal can quickly identify the plane. By setting the anchor point on the center line of the virtual scene in the AR content writing program of the AR running terminal, and setting the center point of the plane recognized by the AR running program of the AR running terminal in association with the anchor point, the virtual scene can be The position of the center point is always located at the center point surrounded by more than two AR running terminals, and the compass sensor is called in real time in the AR running program to make the direction of the virtual scene correspond to the real orientation, so as to realize the knowledge of the known angles in the common scene. Shared experience.

Description

technical field [0001] The invention relates to the technical field of augmented reality, in particular to a multi-person sharing interaction method for augmented reality in a plane recognition mode. Background technique [0002] Augmented reality technologies based on plane recognition patterns of ordinary planes, such as ARcore technology of Google, ARkit technology of Apple, and Surface AR technology of Microsoft. The technology can realize a single fixed positioning of the virtual scene in the real space and a multi-person shared interactive experience in the form of an unknown angle and an unknown center point of the virtual scene by means of plane recognition. However, in the face of ordinary floors and desktops, especially when facing classroom floors, classroom desks, exhibition hall floors, and exhibition hall exhibition countertops, because these surfaces often do not have many feature points, relatively fixed and brighter patterns, in the When selecting the posit...

Problems solved by technology

However, when facing ordinary floors and desktops, especially when facing classroom floors, classroom tabletops, exhibition hall floors, and exhibition hall countertops, because these surfaces often do not have many feature points, relatively fixed and brighter patterns, in When selecting the positioning point of the virtual scene, it will be difficult to identify the plane (the limit angle is much higher than 30 degrees, people need to stand and find the plane through large-scale mobile devices), the scene is unstable (the positioning is easy to lose or drift), etc. Inconvenient situation

And when multiple people share the experience, it is difficult to realize the coordinates of the same center point of the virtual scene and the relatively known (same or different) angles. Although these shortcomings can be made up for by means of GPS, compass, and space recognition, the GPS error is too large and indoor Not applicable, the compass can correct the direction but cannot judge the center point, and the spatial recognition will fail when facing similar spaces (such as classrooms), and the error is also large
