Embodiment 1

[0041] The method for realizing augmented reality in the embodiment of the present invention, such as figure 1 As shown, it mainly includes the following steps: step S101, real-time acquisition of images of the environmental scene; step S102, extraction of image features in the environmental scene image; step S103, initial positioning of the environmental scene according to the image features, and establishment of a local map of the environmental scene ; Step S104, tracking the image frames in the environment scene image; Step S105, displaying the virtual object in the current frame image of the environment scene image according to the pose of the virtual object to be displayed.

[0042] In this technical solution, through the real-time image acquisition of the environmental scene, the image features in the real-time image of the environmental scene are extracted, such as the ORB (Oriented Brief) feature, and the initial positioning of the environmental scene is performed accor...

Embodiment 2

[0056] The server 200 for implementing augmented reality in the embodiment of the present invention, such as figure 2 As shown, it includes: video acquisition module 201: used to acquire the video image of the environmental scene; scene reconstruction module 202: used for performing three-dimensional scene reconstruction on the environmental scene according to the environmental scene video image acquired by the video acquisition module 201; database construction Module 203: for constructing an image retrieval database of the environmental scene according to the video image of the environmental scene acquired by the video acquisition module 201 .

[0057] In this technical solution, the video acquisition module 201 shoots or acquires a pre-shot video image of an environmental scene, and records image details in the environmental scene. The scene reconstruction module 202 performs three-dimensional reconstruction of the environment scene according to the video image of the envi...

Abstract

The invention provides an AR realizing method. The method comprises the following steps that an image of an environment scene is collected in real time; image features are extracted from the image of the environment scene; according to the image features, the image scene is positioned initially, and a local map of the environment scene is established; image frames in the image of the environment scene are tracked; and according to a pose of a virtual object to be displayed, the virtual object is displayed in a present frame of the image of the environment scene. The invention provides an AR realizing server, terminal and system. Via the AR realizing method, server, terminal and system, images of the virtual object of the environment scene or target object can be displayed in an overlapped way under the template free condition, rely on a planar template of a present AR technology is reduced effectively, the real-time registering accuracy between the virtual object and the real environment scene is improved, and the virtual object is much more coordinated and consistent with the overlapped image of the environment scene.

Description

technical field [0001] The present invention relates to the technical fields of artificial intelligence and computer vision, in particular to a method, server, terminal and system for realizing augmented reality. Background technique [0002] Simultaneous Localization and Mapping (SLAM) is a technology applied to the combination of autonomous map creation and self-positioning in an unknown environment. It is a 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 virtual objects into the real environment through ima...
