Abstract

The present invention provides a method for realizing augmented reality based on plane detection, comprising the following steps: acquiring a video image of an environmental scene in real time through a camera; determining an area of ​​interest in a current frame of the video image of the environmental scene, and detecting the area of ​​interest the plane in the region of interest; according to the plane in the region of interest, render the virtual object in the current frame of the video image of the environment scene. The invention also provides a device for realizing augmented reality based on plane detection. The method and device for realizing augmented reality based on plane detection in the present invention detect the plane in the area of ​​interest of the user in the video image of the environment scene, so that the posture of the superimposed and rendered virtual object is consistent with the plane of the superimposed position, which significantly improves the relationship between the virtual object and the plane of the superimposed position. The fitting degree of the real environment scene realizes the seamless integration of virtual objects and real environment.

Description

technical field [0001] The invention relates to the technical fields of computer vision and artificial intelligence, in particular to a method and device for realizing augmented reality based on plane detection. Background technique [0002] SLAM (Simultaneous Localization and Mapping, simultaneous positioning and map creation) is a technology applied to the combination of autonomous map creation and self-positioning in an unknown environment. It is a current research hotspot in the field of autonomous navigation. Finally, how to perceive the surrounding environment and construct an incremental map, while positioning itself, is currently mainly used in technical directions such as unmanned driving, robots, and three-dimensional reconstruction of scenes. [0003] Augmented reality technology (Augmented Reality, AR) uses computer graphics technology and visualization technology to generate virtual objects that do not exist in the real environment, and accurately integrates vir...
