Abstract
The present disclosure relates to other-ship tracking monitoring for tracking and monitoring other ships around a ship, and includes a sensor information collection unit, a selection information collection unit, a tracking camera unit configured to track a selected other ship and collect an enlarged image, and a control unit, wherein the control unit controls the tracking camera unit by considering a size and a position of the selected other ship appearing in the image information.
Claims9
An other-ship tracking monitoring system comprising:
- a sensor information collection unit configured to generate a wide-angle image of a sea area around an own ship;
- a tracking camera unit configured to track another ship included in the wide-angle image and collect an enlarged image;
- and
- a control unit configured to control the tracking camera unit by considering a position of the other ship included in the wide-angle image,
- wherein the control unit is configured to calculate, based on the other ship not being located in a preset center area in the enlarged image, an offset between a center of the enlarged image and a center of a bounding box of the other ship, and control the tracking camera unit based on the offset such that the other ship is located in the preset center area of the enlarged image.

An other-ship tracking monitoring method comprising:
- a sensor information collection operation of generating a wide-angle image of a sea area around a ship;
- a selection information collection operation of receiving selection information about another ship that is selected based on the wide-angle image;
- a tracking camera control value generation operation of generating a control value for controlling a tracking camera by considering a position of the selected other ship appearing in the wide-angle image;
- and
- an enlarged-image collection operation of collecting an enlarged image of the selected other ship from the tracking camera based on the control value,
- wherein the tracking camera control value generation operation comprises:
- based on the other ship not being located in a preset center area in the enlarged image, calculating an offset between a center of the enlarged image and a center of a bounding box of the other ship;
- and
- generating a control value based on the offset such that the other ship is located in the preset center area of the enlarged image.
