Embodiment 1

[0035] figure 1 It shows the flow chart of the first virtual object display method provided by the embodiment of the present application. In this embodiment, after the user places an anchor point on a terminal device, the virtual object corresponding to the anchor point can also be displayed on other terminal devices. objects, as detailed below:

[0036] Step S11, the first terminal device sends the established environment map to other terminal devices, the environment map includes anchor point information and visualization information of the surrounding environment, and the visualization information includes map points, key points and key frames;

[0037] In this step, after starting the AR function of the first terminal device, if it is detected that the user places an anchor point on the screen of the first terminal device, a current environment map of the first terminal device is established. Since the established environment map usually includes a space composed of vario...

Embodiment 2

[0076] figure 2 It shows a flow chart of the second virtual object display method provided by the embodiment of the present application, and the virtual object display method is applied to the second terminal device, including:

[0077]Step S21, receiving the environment map sent by the first terminal device, the environment map includes anchor point information and visualization information of the surrounding environment, and the visualization information includes map points, key points and key frames;

[0078] Wherein, the first terminal device here refers to a terminal device different from the second terminal device.

[0079] The anchor point information in this step refers to posture information of the virtual object and the like.

[0080] Step S22, according to the environment map and the acquired visual frame, calculate the relative positional relationship in the reference coordinate system corresponding to the first terminal device, according to the relative position...

Embodiment 3

[0092] image 3 It shows the flow charts of three virtual object display methods provided by the embodiment of the present application, and the virtual object display method is applied to the first terminal device, including:

[0093] Step S31, establishing an environment map, the environment map includes anchor point information and visualization information of the surrounding environment, and the visualization information includes map points, key points, and key frames;

[0094] Specifically, an environment map is established according to the pose information of the camera and the image frames acquired by the camera, and the camera is set on the first terminal device.

[0095] Step S32, sending the established environment map to the non-first terminal device, instructing the non-first terminal device to calculate the relative positional relationship with the reference coordinate system corresponding to the first terminal device, and the non-first terminal device Including t...

Abstract

This application is applicable to the technical field of software application, and provides a virtual object display method, a terminal device, and a computer-readable storage medium, including: receiving an environment map sent by a first terminal device, and the environment map includes anchor point information and surrounding environment information. visualization information, the visualization information includes map points, key points, and key frames; according to the environment map and the acquired visual frames, calculate the relative positional relationship with the reference coordinate system corresponding to the first terminal device; according to the The relative positional relationship is displayed, and the virtual object corresponding to the information of the anchor point is displayed. Through the above method, there is no need to be affected by other servers when implementing the AR technology.

Description

technical field [0001] The present application belongs to the technical field of software application, and in particular relates to a virtual object display method, a terminal device and a computer-readable storage medium. Background technique [0002] Augmented reality (Augmented Reality, AR) is a technology that calculates the position and angle of the camera image in real time and adds the corresponding image. The goal of this technology is to put the virtual world on the screen and interact with the real world. [0003] The current multi-person AR technology solution is multi-person AR technology based on cloud anchors. ARCore (ARCore is a software platform for building augmented reality applications launched by Google. It can take advantage of advances in cloud software and device hardware to place digital objects to the real world) as an example, which involves hosting the visual mapping data (such as key point information, map point information) and anchor point infor...
