Abstract:
A method of synchronizing video frames of a moving object captured from a plurality of video cameras, said method comprising the steps of:capturing a first sequence of video frames from a first video camera; capturing a second sequence of video frames from a second video camera; calculating the time difference between the start of said first sequence of video frames and the start of said second sequence of video frames; and synchronizing said first sequence of video frames to said second sequence of video frames in accordance with said time difference, wherein said calculating step includes the steps of: processing said first sequence of video frames to derive a first mathematical model of the motion of said object represented by said first sequence of video frames; processing said second sequence of video frames to derive a second mathematical model of the motion of said object represented by said second sequence of video frames; and comparing said first mathematical model to said second mathematical model to calculate said time difference.
