Embodiment 1
[0054] figure 1 The implementation flow of the video matching method provided by Embodiment 1 of the present invention is shown, and the details are as follows:
[0055] In step S101, all key frames of the target video are extracted, and feature information of each target key frame is saved.
[0056] Among them, the target video is a video of learners who are learning and imitating the actions in the teaching film. The process of extracting all key frames of the target video is as follows: figure 2 shown, including:
[0057] Step S201, read the current video frame of the target video, and use the current video frame as the first key frame;
[0058] Step S202, acquiring feature information of the first key frame;
[0059] Step S203, reading the next video frame;
[0060] Step S204, acquiring feature information of the next video frame;
[0061] Step S205, comparing the feature information in the two video frames to obtain the matching degree;
[0062] Step S206, if the m...
Embodiment 2
[0086] Figure 8 A specific structural block diagram of the video matching device provided by Embodiment 2 of the present invention is shown, and for convenience of description, only parts related to the embodiment of the present invention are shown. The video matching device may be a software unit, a hardware unit or a combination of software and hardware built in a computer, television or mobile terminal. The video matching device includes: a feature information acquisition unit 51 and a matching degree acquisition unit 52 .
[0087] Wherein, the feature information acquisition unit 51 is used to extract all key frames of the target video, and save the feature information of each target key frame;
[0088] The matching degree acquisition unit 52 is used to compare the feature information of each target key frame saved by the feature information acquisition unit 51 with the feature information of the pre-generated source video key frame to obtain the matching degree of the ta...

Abstract
The invention relates to the technical field of video and provides a video matching method and device. The method comprises the steps that all key frames of target video are extracted, feature information of each target key frame is stored; the feature information of the target key frames is compared with feature information of source video key frames generated in advance, and the matching degree of the target video and source video is obtained. The teaching source video is analyzed in advance, when a learner carries out learning, application software only needs to analyze the target video of the learner, the situation that two-way video is analyzed at the same time is avoided, and half of CPU operation consumption is lowered.
Description
technical field [0001] The invention belongs to the field of video technology, and in particular relates to a video matching method and device. Background technique [0002] At present, video learning application software developed by R&D personnel, such as golf learning application software, generally plays golf video teaching videos, and at the same time captures videos of learners who are learning and imitating the actions in the teaching videos through the camera, and compares the teaching videos and the teaching videos frame by frame. The actions of the learner's video image frames are used to guide the learner. But usually this kind of direct comparison of two video frame data will consume a lot of central processing unit (Central Processing Unit, CPU) resources. Relatively slow, resulting in slow response of TV or other consumer electronic devices. Contents of the invention [0003] The embodiment of the present invention provides a video matching method and devic...
