Spatial positioning method and device based on augmented reality

Abstract

The invention relates to the field of spatial positioning, and discloses an augmented reality-based spatial positioning method and device. In the present invention, the augmented reality-based spatial positioning method includes: obtaining the offset angle of the dual-camera coordinate system relative to the world coordinate system; wherein the world coordinate system is a coordinate established in advance with the known target position of the positioning photosphere as the reference coordinate obtain the actual position of the positioning photosphere in the world coordinate system; calculate the coordinate value of the dual camera in the world coordinate system according to the offset angle, the actual position and target position of the positioning photosphere; according to the coordinate value of the dual camera in the world coordinate system , to determine the position of the virtual object in the virtual space in the world coordinate system. The invention also discloses a space positioning device based on augmented reality. Compared with the prior art, the present invention can ensure that the positions of the virtual object and the positioning photosphere are coincident, so that the virtual object and the real object can be closely combined in the virtual scene.

Description

technical field [0001] The present invention relates to the field of space positioning, in particular to a space positioning method and device based on augmented reality. Background technique [0002] AR (AR is the abbreviation of Augmented Reality, Chinese interpretation is augmented reality technology or augmented reality) is a technology that calculates the position and angle of camera images in real time and adds corresponding images, videos, and 3D models. The goal of this technology is Put the virtual world on the screen and interact with the real world. With the improvement of the computing power of the portable electronic product CPU (CPU is the abbreviation of Central Processing Unit, the Chinese interpretation is the central processing unit), it is expected that the use of augmented reality will become more and more extensive. [0003] In the prior art, the AR head-mounted device used by the user usually adopts the Inside-Out solution to locate the virtual object....

Problems solved by technology

[0004] However, the inventors of the present application found in the process of implementing the present invention that there are still the following technical defects in the prior art: when the dual camera device is displaced or rotated relative to the positioning photosphere, the objects in the virtual scene cannot be aligned with the positioning The position of the light sphere coincides, so that the objects in the virtual scene cannot be closely combined with the objects in the real scene
