Method, device and equipment for determining reality scene key frame, and media

Abstract

The invention provides a method, a device and equipment for determining a reality scene key frame, and media. The method comprises the following steps that: carrying out feature matching on the feature points of a current video frame and the feature points of a reference video frame to obtain matched feature point pairs, wherein the reference video frame is a video frame in a reality scene, and the collection time of the reference video frame is different from the collection time of the current video frame; according to a preset screening algorithm, screening the feature point pairs of which the similarity exceeds a first threshold value in the matched feature points; and according to the number of the screened feature point pairs, determining the current video frame as the key frame of the reality scene, and storing the key frame into a scene map corresponding to the reality scene, wherein the scene map is only used for storing the key frame of the reality scene. By use of the method, the key frame of the reality scene is determined without the restriction of a specific scene so as to construct the accurate and reliable reality scene.

Description

technical field [0001] The present invention relates to the technical field of video image processing, in particular to a method, device, medium and equipment for determining a key frame of a real scene. Background technique [0002] Currently, the way to construct AR (Augmented Reality, Augmented Reality) scene is: [0003] Use the camera to collect images in the specific scene where the AR card has been set, and directly determine the captured image as the key frame of the real scene and store it in the scene map corresponding to the real scene, so as to construct the real scene; superimpose the virtual scene to the construction In the obtained real scene, the AR scene is constructed. [0004] Among them, it is necessary to collect the key frames of the real scene in a specific scene, and directly use the image of the specific scene as the key frame of the real scene. If it is outside the specific scene, the key frame of the real scene cannot be determined, and thus the o...
