Embodiment 1

[0134] Embodiments of the present invention provide a method for implementing AR applications, such as figure 1 As shown, the method provided in this embodiment includes:

[0135] 101. Acquire first reference information, where the first reference information is the reference information used when adjusting the calling frequency of an identification module in an augmented reality AR application.

[0136] It should be noted that, in this embodiment, the first reference information is used for the AR application to adjust the calling frequency of the identification module. Specifically, the first reference information includes at least one or more of the following types of information: the display position of the AR virtual content on the terminal screen, the running status of the AR virtual content, the status information of the terminal (such as acceleration information and attitude Information), the quality information of the image frame captured by the camera.

[0137] 102...

Embodiment 2

[0141] For ease of understanding, based on the method provided in Embodiment 1, this embodiment further provides a method for implementing an augmented reality application. In this embodiment, the first reference information is information related to AR virtual content as an example for illustration.

[0142] Such as figure 2 As shown, the method provided in this embodiment includes:

[0143] 201. The terminal obtains relevant information of the AR virtual content currently displayed on the screen from the rendering module of the AR application, and the relevant information includes the position and size of the AR virtual content on the screen.

[0144] 202. The terminal compares the relevant information of the AR virtual content with a preset first threshold, and judges whether the area occupied by the AR virtual content on the screen reaches the first threshold; if yes, execute step 203; if not, Execute step 204.

[0145] 203. The terminal reduces the calling frequency of...

Embodiment 3

[0161] For ease of understanding, based on the method provided in Embodiment 1, this embodiment further provides a method for implementing an augmented reality application. In this embodiment, the first reference information is the running status of AR virtual content as an example for illustration.

[0162] Such as Figure 4 As shown, the method provided in this embodiment includes:

[0163]401. The terminal acquires AR virtual content corresponding to the AR target object through a rendering module in the AR application, and superimposes the AR virtual content on an image frame for display.

[0164] 402. The terminal detects a user's trigger operation, and runs the AR virtual content.

[0165] Specifically, based on the attributes of the AR virtual content, the running of the AR virtual content includes at least the following two ways: playing the AR virtual content, or performing interactive operations on the AR virtual content according to user operations.

[0166] 403. ...

Abstract

The invention discloses a device and method for achieving an AR application, and relates to the technical field of human-computer interaction. The device and method are used for achieving the aim of reasonably setting processing intervals when image frames shot by a camera are processed through the AR application. The device for achieving the AR application comprises an obtaining unit and a processing unit, wherein the obtaining unit is used for obtaining first reference information, the first reference information serves as bases when the calling frequency of an recognition module in the AR application is adjusted, and the processing unit is used for adjusting the calling frequency of the recognition module according to the first reference information obtained by the obtaining unit. The device and method are suitable for the field of human-computer interaction and used for achieving the AR application.

Description

technical field [0001] The present invention relates to the technical field of human-computer interaction, in particular to a device and method for implementing augmented reality applications. Background technique [0002] AR (Augmented Reality, Augmented Reality) technology is a brand-new human-computer interaction technology. It applies virtual information to the real world through smart terminal equipment and visualization technology, so that virtual information and the real world can be superimposed on the same screen or space at the same time and presented to the audience. user. With the popularity of smart terminals, the application of AR technology is becoming more and more extensive, and AR applications can be installed on smart terminals to experience. Specifically, the workflow of the AR application is as follows: the terminal captures the image frame through the camera; recognizes the image frame to determine the AR target object; tracks the AR target object in t...
