Embodiment 1

[0029] According to an embodiment of the present invention, an area AR rendering method is provided, such as figure 1 As shown, the method may specifically include the following steps:

[0030] S102. When the target terminal moves from the first position to the second position, determine an overlapping area between the first area corresponding to the first position and the second area corresponding to the second position;

[0031] In this embodiment, the target terminal includes, but is not limited to, mobile terminals such as mobile phones and microcomputers, and the target terminal includes functions such as image collection and image display. For the scene where the target terminal is located, the AR scene is rendered based on the location information of the target terminal. The rendering can be performed according to the AR rendering data and the image information collected by the target terminal, and can also be determined according to the AR data and other image acquisi...

Embodiment 2

[0064] An area AR rendering method provided by an embodiment of the present invention is introduced in detail, such as Figure 4 As shown, specifically, the following steps may be included:

[0065] S401, acquire the location information of the target terminal

[0066] Specifically, the latitude and longitude information of the target terminal passing through the first location is acquired, and the preset distance threshold r of the radius is selected.

[0067] S402. Determine a central area and a peripheral area of ​​the first area;

[0068] Specifically, taking the longitude and latitude of the first location of the target terminal as the center, determine a circle with a radius equal to a preset distance threshold r as the central area of ​​the first area, and load and initialize the AR rendering information of the central area. Taking the latitude and longitude of the first location where the target terminal is located as the center, use a ring with an outer radius of 2r...

Embodiment 3

[0081] An area AR rendering device provided by an embodiment of the present invention is introduced in detail.

[0082] refer to Figure 5 , shows a schematic structural diagram of an area AR rendering device in an embodiment of the present invention.

[0083] The application program loading device in the embodiment of the present invention includes: a first determination module 50 , a first acquisition module 52 , and a rendering module 54 .

[0084] The functions of each module and the interaction between each module are introduced in detail below.

[0085] The first determination module 50 is configured to determine the overlap between the first area corresponding to the first position and the second area corresponding to the second position when the target terminal moves from the first position to the second position area;

[0086] The first acquiring module 52 is configured to acquire the first AR rendering data corresponding to the overlapping area from the local data...

Abstract

The invention provides a region AR rendering method and device, electronic equipment and a readable storage medium, and relates to the technical field of AR rendering. The method comprises the following steps: when a target terminal moves from a first position to a second position, determining an overlapped area between a first area corresponding to the first position and a second area corresponding to the second position; first AR rendering data corresponding to the overlapping area is obtained from a local database of the target terminal, second AR rendering data corresponding to an independent area is obtained from a preset server, and the independent area is an area except the overlapping area in the second area; and loading the first AR rendering data and the second AR rendering data in the target terminal. Therefore, the problem that the AR scene is not smooth after being switched due to the change of the moving position of the terminal in the related technology can be solved.

Description

technical field [0001] The present invention relates to the technical field of AR rendering, in particular to an area AR rendering method, device, electronic equipment and readable storage medium. Background technique [0002] At present, AR (Augmented Reality, real-time content rendering) content is rendered in real time based on the large space of 5G (5th Generation Mobile Communication Technology) and MEC (Mobile Edge Computing), and most business systems have a single implementation method , AR landscape rendering application development efficiency is very low. [0003] In AR landscape rendering, there are two main methods: [0004] One way is to render the entire area first. When the user moves around the area with the AR device, the AR screen can switch smoothly. However, the overall rendering takes a long time and has high requirements on the performance of the device. [0005] Another way is to only render the area where the device is located, which takes less tim...
