Embodiment 1

[0036] Such as figure 1 Shown, based on the large-screen display method of augmented reality, described method carries out the following steps:

[0037] Step 1: Use three image acquisition units to acquire images of objects in the current scene to obtain three scene images;

[0038] Step 2: Perform image denoising processing on the three scene images respectively, and then perform image color channel separation to obtain red channel images, blue channel images and yellow channel images respectively;

[0039] Step 3: Perform image fusion on the three scene images to obtain the fused scene image;

[0040] Step 4: Carry out image recognition on the fused scene image, identify the real object in the scene image, and obtain the recognition result;

[0041] Step 5: Based on the recognition result, retrieve the data information corresponding to the object in the database;

[0042] Step 6: Send the physical object and corresponding data information to the large-screen display for d...

Embodiment 2

[0048] On the basis of the previous embodiment, in the step 6, superimposing each data information on the corresponding position of the corresponding real object for display includes: determining the real-time posture of the image acquisition unit relative to the real object according to the scene image information; according to the image acquisition parameters and real-time attitude information of the image acquisition unit, and the pre-stored three-dimensional material information corresponding to the real object, obtain the three-dimensional display information corresponding to the real object and the current real-time attitude, and store the three-dimensional display information corresponding to the real-time attitude The three-dimensional display information is superimposed on the corresponding position of the scene image for display, and the three-dimensional display information includes three-dimensional display information for simulating the real object.

Embodiment 3

[0051] On the basis of the previous embodiment, according to the image acquisition parameters and real-time attitude information of the image acquisition unit, as well as the pre-stored three-dimensional material information corresponding to the real object, obtain the real-time attitude corresponding to the real object and the current The three-dimensional display information includes: obtaining a projection matrix according to the real-time posture information and the image acquisition parameters of the image acquisition unit;

[0052] For each vertex in the pre-stored three-dimensional material information corresponding to the real object, calculate the pixel imaging position corresponding to the vertex on the imaging plane according to the projection matrix, and determine the pixel imaging position according to the color information of the vertex The corresponding color information at the position.

[0053] Specifically, the binarization process of the image is to convert ...

Abstract

The invention relates to the field of augmented reality technology, in particular to a large-screen display method and device based on augmented reality. The method performs the following steps: step 1: through three image acquisition units, image acquisition is performed on the real object in the current scene to obtain three scene images; step 2: image denoising processing is performed on the three scene images respectively, and then Image color channels are separated to obtain a red channel image, a blue channel image and a yellow channel image respectively; Step 3: Perform image fusion on the three scene images to obtain a fused scene image. It completes the multi-angle acquisition of the scene through multiple acquisitions and multiple recognitions of the images in the scene, and then separates and fuses the image channels according to the multi-acquisition results, so as to maximize the restoration of the details in the scene. After the recognition Call relevant data for feedback and projection, combined with augmented reality, realize the corresponding display of scenes and images, and improve the authenticity of the display.

Description

technical field [0001] The invention belongs to the technical field of augmented reality, and in particular relates to a large-screen display method and device based on augmented reality. Background technique [0002] Augmented Reality (Augmented Reality) technology is a technology that ingeniously integrates virtual information with the real world. It uses a variety of technical means such as multimedia, 3D modeling, real-time tracking and registration, intelligent interaction, and sensing to integrate computer-generated Text, images, 3D models, music, video and other virtual information are simulated and applied to the real world, and the two kinds of information complement each other, thereby realizing the "enhancement" of the real world. [0003] Augmented reality technology can not only effectively reflect the content of the real world, but also promote the display of virtual information content, and these delicate contents complement and superimpose each other. In the...
