Label display method, device, equipment and storage medium

Abstract

The invention discloses a label display method, device, equipment and storage medium. The method includes: dividing the range of the camera's field of view into N levels of field of view according to the maximum field of view and the minimum field of view of the camera; Obtain and save the AR tags added on the video screen captured by the camera at different FOV levels; among them, the AR tags include tag configuration information and the FOV level to which the AR tag belongs; determine the camera’s FOV level according to the current FOV of the camera The field of view level to which the current field of view belongs, and the AR label corresponding to the level of field of view to which the current field of view belongs is displayed on the real-time video screen captured by the camera; so that the AR label is only in the current field of view when the camera is shooting. It is only displayed when the field of view of the tag configuration is at the level, and hidden in other cases, realizing the hierarchical display of AR tags, optimizing the display of AR tags, and avoiding the situation where tags are blocked by too many tags added to the video screen.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a label display method, device, equipment and storage medium. Background technique [0002] Augmented reality refers to the use of computer-generated enhancements to add new information to images in real-time or near real-time, labeling, virtualizing elements in the real world, and labeling, virtualizing elements on the screen Sets are overlaid and rendered in the real world. With the development of technology, the technology of superimposing augmented reality tags (that is, AR tags) on camera videos has broad application prospects in the field of urban monitoring. AR tags are the link that organically connects real-world information with the virtual world, carried by AR tags. The information can be extended to a large number of augmented reality applications. [0003] At present, the method of displaying AR tags on the image screen of the AR system is relative...

Problems solved by technology

[0003] At present, the method of displaying AR tags on the image screen of the AR system is relatively simple. Most of them are based on the plane coordinates to display the AR tags on the point information of the image screen. The entities marked by the AR tags are at different distances from the camera, and the AR tags are all on the same plane. The display cannot reflect the hierarchical relationship between far and near. At the same time, for a city-level surveillance system, there may be thousands of tags added to the image. When the AR tags are dense, they will occlude each other and be difficult to distinguish.
