Problems solved by technology

This brings the following main problems: the calculation of the pattern matching process is slow, and the calculation time increases with the increase of the number of markers in the database; maintenance is not convenient
But the above-mentioned two-dimensional visualization coding does not support the augmented reality function similar to the three-dimensional information in ARToolkit

Embodiment Construction

[0050] Referring to Fig. 3, the present invention provides a method for realizing three-dimensional augmented reality, which is mainly realized through the following steps:

[0051] 301: Initialize the 3D graphics system environment, camera internal parameters and marker files;

[0052] Among them, the goal of the graphics system environment initialization is to set up a drawing environment that can support both 2D graphics and 3D graphics, including obtaining and setting display modes, setting display parameter lists, display devices, creating display surfaces, setting display surface parameters, setting viewpoint positions and view plane etc.

[0053] The internal parameters of the camera refer to the internal intrinsic parameters such as the focal length and deformation of the camera camera. This parameter determines the projection transformation matrix of the camera camera. It depends on the properties of the camera itself, so its internal parameters are constant for the s...

Abstract

The invention discloses a method and system of implementing 3D augmented reality, and the method comprises: video frame capture module captures video frames of 2D visual code mark in real environment; performing augmented reality processing on the obtained video frames and obtaining the processed virtual graphic frames; virtual-real synthesis module synthesize the obtained virtual graphic frames and the obtained video frames and obtaining the synthesized video frames of augmented reality. And the invention can better support implementation of the augmented reality technique in handheld mobile computers with relatively limited resources and expanding the application field of the augmented reality technique.

Description

technical field [0001] The invention relates to augmented reality technology, in particular to a method and system for realizing three-dimensional augmented reality. Background technique [0002] Augmented reality (AR, Augmented Reality) is a technology that uses virtual objects to enhance the reality of real scenes. Augmented reality retains the physical environment that the user is actually in as the user's main perception and interaction environment, and marks the virtual generated information such as text, two-dimensional images, and three-dimensional models on the objects in the physical environment displayed on the display screen, thereby Realize the annotation and description of the real physical environment in which the user is in, or enhance and emphasize certain effects of the real environment. For example, the user wears special augmented reality display glasses and visits the Forbidden City in person. When he visits a cultural relic, he Not only can you see the ...
