Abstract: The present invention relates to a vessel traffic service system and a method for extracting accident data, and more particularly, to a technique that search and extracts possible event traffic data automatically from data of a concerned area without knowing exact time when a marine accident occurs. The vessel traffic service system includes: an input unit receiving conditional information for extracting accident occurrence data from a user; a storage unit storing at least one of an automatic identification system (AIS) signal, a radar signal, and a camera image signal; and a control unit extracting an event occurrence part from at least one of the AIS signal, the radar signal, and the camera image signal of a point and a time at which an accident occurs in accordance with the conditional information to generate an accident candidate list.

Abstract: The traffic control method according to the present invention includes obtaining radar information on a target from at least one radar; obtaining AIS information of the target from an AIS (automatic identification system) of the target; detecting GPS jamming; and fusing the radar information and the AIS information. The fusing selectively fuses the AIS information depending on whether the GPS jamming occurs in the position of the target as a result of the detection.

Abstract: The present invention relates to an apparatus and method that control a vessel deviating from an anchorage using wide-range sensor-based spherical trigonometry. In the method, vessels anchored in an anchorage are monitored. The anchorage is defined as a group, and the group of the anchored vessels is managed. Leaving of a vessel, needing to deviate from the anchorage, from the group is controlled. If a vessel recognized as a vessel identical to one that left the group requests anchoring after a predetermined period of time has elapsed, the anchoring-requesting vessel is controlled.

The risk calculation unit calculates the degree of risk of the collision between the objects using the processed input information. The provision unit externally outputs the degree of risk of the collision, and performs control so that the risk of the collision between the objects can be externally predicted.

Abstract: An apparatus and method for providing traffic control service are disclosed herein. The apparatus for providing traffic control service includes a multi-sensor fusion processing unit, an image object tracking and combination unit, and an information provision unit. The multi-sensor fusion processing unit generates the location information of a vessel by fusing radar information and automatic identification system (AIS) information together. The image object tracking and combination unit sets a detection area on a closed-circuit television (CCTV) image based on the information of the vessel, and detects the vessel by performing image processing within the set detection area. The information provision unit generates mapping display information based on the information of the vessel and the result of the detection achieved by performing the image processing, and displays the generated mapping display information within a CCTV screen, thereby providing traffic control service.

Abstract: Disclosed herein are a method and apparatus for managing tracking information using a unique ID in a Vessel Traffic System (VTS). In the method, a multi-sensor integration system issues a unique ID corresponding to a target, and sends a tracking command including the unique ID to radar tracking systems. The multi-sensor integration system receives first tracking information reports corresponding to the unique ID from the radar tracking systems. The multi-sensor integration system generates a second tracking information report by integrating the first tracking information reports using the unique ID. The multi-sensor integration system sends the second tracking information report to a system administrator so that information about tracking of the target is provided to the system administrator.
