1. A video splicing method, comprising:
acquiring a first video and a second video which are to be spliced, wherein the first video is before the second video;
performing frame freeze detection on the first video or the second video so as to obtain a freeze frame sequence;
obtaining a reference video frame on the basis of the freeze frame sequence;
searching for an overlapping area on the basis of the reference video frame so as to obtain a first overlapping video frame area of the first video and a second overlapping video frame area of the second video; and
splicing the first video and the second video on the basis of the first overlapping video frame area and the second overlapping video frame area to obtain a spliced video,
wherein the operation of performing frame freeze detection on the first video or the second video so as to obtain a freeze frame sequence comprises:
converting the first video or the second video into a plane video; and
performing the frame freeze detection on the plane video so as to obtain the freeze frame sequence.
