摘要:
Video synchronization apparatus (200) is a video synchronization apparatus including a processor and a storage connected to the processor. The processor performs a detection step (S12) of detecting a first feature point in a first image frame in a first video, and a second feature point in each of a plurality of second image frames in a second video, an extraction step (S14) of extracting matching points that are a set of the first feature point and a second feature point that is similar to the first feature point, and a synchronization step (S15 or S16) of determining a second image frame to be synchronized with the first image frame, based on a first degree of satisfaction, by a matching point in each second image frame, of a first geometric relationship between the each second image frame and the first image frame.
