Embodiment 2

[0084] figure 2 It is a flow chart of the method for automatically generating dynamic data based on video motion estimation in embodiment 1, as figure 2 As described, the method for automatically generating dynamic data based on video motion estimation in this embodiment includes:

[0085] S21: Load the video image, and assign codes to the frames in the video image according to the playback order.

[0086] Specifically, the loaded video image can be any video image, including a complete movie video or a part of a movie video, it can be a black and white video or a color video, it can be a silent video, and the video image is composed of frames. For example, there are 24 frame pictures per second, any frame picture has a picture motion vector, and the shape of each frame picture is the same.

[0087] S22: Acquiring the first frame picture and the second frame picture.

[0088] Specifically, any frame in the video image is acquired as the first frame, and any frame in the v...

Abstract

The invention discloses a method for automatically generating dynamic data based on video motion estimation. The method comprises the following steps: loading a video image, endowing a frame in the video image with a code according to the play order, and acquiring a first frame and a second frame to obtain a sprite; acquiring an original sprite, acquiring a contrast sprite from the second frame, establishing a plane coordinate system on the frame and substracting coordinate figures in the contrast sprite by coordinate figures in the original sprite to obtain a motion vector of the original sprite; acquiring a motion vector set and clustering to obtain at least one cluster; acquiring a cluster containing most motion vectors as a target cluster, acquiring an average value of the motion vectors in the target cluster to serve as a frame motion vector in the first frame; acquiring frame motion vectors of all the frames and calculating dynamic data of the video image. By adopting the methodprovided by the invention, the experience requirements on workers can be reduced.

Description

technical field [0001] The present invention relates to the field of dynamic data, and more particularly, relates to a method for automatically generating dynamic data based on video motion estimation. Background technique [0002] In modern society, watching movies is one of the main entertainment methods for people. With the development of 3D movie technology, dynamic seats that can make corresponding actions as the movie plot changes are gradually known to people. [0003] A dynamic seat is a seat that can perform specific actions. People use the preset dynamic data to control the dynamic seat to make corresponding actions according to the changes in the movie plot. The dynamic data is used to control the motion parameters of the dynamic seat. . By controlling the dynamic seat to make actions such as vibration, shaking or movement that change with the movie video, it will bring the audience a motion experience other than the audio-visual experience, making the audience i...
