A kind of generation of ship video of chain of evidence form and display methods

The invention provides a kind of generation of ship video of chain of evidence form and display methods, the monitoring visual field scope of video camera is calculated using information such as the position of CCTV camera, height and directions, ship target entrance is extrapolated according to the AIS information of ship target ship and sails out of the time of each camera supervised scope, the time point that foundation calculates, which intercepts video segment and is sequentially arranged from the monitoring video of each video camera, forms chain of evidence；In discovery chain video, the moving ship target in video is detected first and obtains the AIS information of all ships entered in the period in the camera supervised scope, then the video image information of ship and AIS information fusions are got up, while showing ship image, the AIS information such as identity, operational configuration and sail plan of each ship is shown.
