[0029] The present invention will be further described in detail below in conjunction with specific embodiments and with reference to the drawings.
[0030] Video data may contain more than 20 frames of images in one second. Considering that the sequence video data contains rich information and the characteristics of high overlap between adjacent frame images, the present invention proposes a method for extracting key frames of sequence video. The present invention is suitable for three-dimensional reconstruction and measurement of sequence video and compression of sequence video data. Traditional three-dimensional reconstruction methods mostly incorporate all sequence videos into the reconstruction process. Compared with traditional methods, the present invention can improve the quality of reconstruction and reduce the cost of reconstruction. The structure diagram of the present invention is in figure 1 The frame diagram of the key frame extraction method for sequence video is s...
