Abstract

The invention discloses an augmented reality method, device and system which are used for performing augmented reality on a shot scene at a mobile terminal. The augmented reality method comprises thesteps of turning on a camera of the mobile terminal, aligning to a real target building, and obtaining current space parameters of the mobile terminal; calculating a virtual target building corresponding to the real target building in a low-precision three-dimensional model according to a space relation in the low-precision three-dimensional model by combining the preset low-precision three-dimensional model on the basis of the current space parameters of the mobile terminal, obtaining basic information corresponding to the virtual target building in the low-precision three-dimensional model;and finally displaying the obtained basic information on the real target building in an overlapped manner. The three-dimensional geometric space algorithm adopted by the invention is simple, the required calculating resources are limited, the storage space required by the low-precision three-dimensional model is very small, the real-time performance is high, and application range is wide.

Description

technical field

[0001] The invention belongs to the technical field of augmented reality, in particular to an augmented reality method, device and system based on low-precision three-dimensional model space calculation. Background technique

[0002] Augmented Reality (AR for short) is a technology that superimposes corresponding images, videos, and 3D models on real scenes in real time. The goal of this technology is to put the virtual world on the screen and interact with the real world. In the practical application of augmented reality technology, it is usually necessary to use technologies such as image or video recognition, or to use identification methods to obtain the formatted information of the environment in which the real scene is located. Due to the current technical limitations of image or video recognition technology, it is currently difficult for augmented reality to obtain accurate information about the environment in which it is located. However, the identif...
