Problems solved by technology
At present, there are many technologies for adding special effects on the plane of the video. Adding special effects on the plane requires continuous tracking of the plane, otherwise the special effects may be unstable. However, the current plane tracking technology often discriminates the feature points outside the plane. In the case of feature points in the plane, the plane tracking in the video is unstable, which leads to the problem of adding instability to special effects

The invention relates to a method and device for determining a plane in a video, a storage medium and electronic equipment, and the method comprises the steps: determining a target vanishing line of a video frame based on the target plane direction of the video frame for the video frame in the video; determining a target area in the video frame according to the target vanishing line and the target plane direction of the video frame; and determining a target plane in each video frame of the video based on the feature points in the target area in each video frame. According to the invention, plane misjudgment caused by misjudgment of points on a non-plane as points on a plane can be reduced, so the plane determination precision is improved.
Description
technical field [0001] The present disclosure relates, in particular, to a method and device for determining a plane in a video, a storage medium and an electronic device. Background technique [0002] Video is a mainstream form of multimedia. With the development of shooting technology and video production technology, video special effects have become a major topic in the field of video processing. Because the video usually records a three-dimensional scene, and if the three-dimensional special effect wants to achieve a natural effect, it needs to be adjusted according to the position, angle and other parameters of the video scene. At present, there are many technologies for adding special effects on the plane of the video. Adding special effects on the plane requires continuous tracking of the plane, otherwise the special effects may be unstable. However, the current plane tracking technology often discriminates the feature points outside the plane. In the case of featur...
