Problems solved by technology

[0003] Generally, the content of the live broadcast screen changes frequently, and the shooting position changes greatly. If the AR special effects rendering is performed on the live broadcast screen, a fixed angle or area will be selected, and it is impossible to perform real-time AR spec

Embodiment Construction

[0034] Most of the existing AR live broadcast technologies are still based on the screen level, that is, various simple special effects content appear on the screen. This kind of special effect does not need to understand the scene content. It only needs to set the presentation position of the special effect on the screen and play the special effect animation will do. Portrait-level AR special effects rely on AR recognition and tracking algorithms, such as facial feature recognition, superimposed virtual props and stable tracking. In addition, there are similar AR special effects triggered by gesture recognition, and AR special effects triggered by facial recognition. However, this type of special effect method is suitable for people and most of them are used for small videos and shooting. The accuracy of face detection is not high. If the first shot is not accurate, you can take it again. The user’s fault tolerance rate Also relatively high. Some TV programs use scene-level...

Abstract

The invention discloses a video processing method and device. The method comprises the following steps: acquiring a video stream; acquiring a video stream; performing special effect processing on eachframe of image including a target object in the video stream to enable the target object to be surrounded by a special effect; wherein the three-dimensional degree of the special effect is determinedaccording to a posture when a shooting device collects an image of the current superimposed special effect. According to the position information and the contour information of the target object in the image or the posture of the shooting device when the shooting device collects the image with the current superimposed special effect, special effect superposition is carried out on the real targetobject in the image, interaction between the special effect and the target object is facilitated, better special effect display is brought, understanding of the video stream is enriched, therefore, the appreciation and comprehensiveness of video stream presentation are improved, the understanding of audiences on the video stream can be simplified through the virtual-real combination mode, and thevisual perception of the audiences is improved.

Description

technical field [0001] The present application relates to the field of image processing, and in particular to a video processing method and device. Background technique [0002] Adversarial games are short in duration, complex in game rules, intense and exciting, and accompanied by a lot of status information updates. If these status information are presented to the audience in the form of data information display, the audience cannot adapt and process so much in a short time. In the process of watching the game video, especially the live game video, the audience is easy to get tired, and it is easy to ignore important information. With the rapid development of online games and mobile games, people of different ages have some understanding of the entry-level special effects of the game. Losing blood or increasing experience can display the blood deduction value or gold coin bonus value above the target object. Therefore, converting the state information into a visual speci...
