Problems solved by technology

[0004] In the existing augmented reality technology solution based on SLAM technology, after the environment recognition and camera pose calculation are completed, the virtual information is directly superimposed and displayed without plane detection, resulting in a low degree of fit between the virtual information and the environmental scene, which is easy to use Users generate visual dislocation, which affects the rendering effect of augmented reality technology

Abstract

The present invention provides a method and device for realizing augmented reality based on plane detection. The method comprises the following steps that: the video images of an environment scene areobtained in real time through a camera; a region of interest in the current frame of the video images of the environment scene is determined, and a plane in the region of interest is detected; and avirtual object is rendered in the current frame of the video images of the environment scene according to the plane in the region of interest. The present invention also provides a device for realizing augmented reality based on plane detection. According to the method and device for realizing augmented reality based on plane detection of the invention, the plane in the region which a user is interested in of the video images of the environment scene is detected; the pose of the virtual object which is to be subjected to superimposed rendering is made to be consistent with the plane of the superimposed position of the virtual object; and therefore, the fitting degree of the virtual object and the real environment scene is obviously improved, and the seamless integration of the virtual object and the real environment can be realized.

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...
