Ships Tagging

Version 2019-12-03

Geometry

This project aims to tag ships in high resolution satellite images (with resolution typically from 30 cm. to 2 m.).

Records should be annotated as an oriented bounding-box (with orientation going from back to front of ship) or as a rectangle i.e. a 4-vertices polygon.

Classes

A taxonomy has been defined in order to represent the different specific cases a user can encounter.

Every record must have either marina, ship or unkown tag. A marina is a dock or basin with moorings and supplies for yachts and small boats.

The tag unknow is used when the user is sure that the object is neither a ship, nor a marina. This one should not be used very often.

When the user recognise an object as a ship, he may be able to go one step further and find the class of the vessel. Eight classes have been selected to represent the whole diversity of the ships that may be encountered. A extra class has been added, unclassified, to be used when the user cannot decide which class to select. For smaller ships, the difference between two ships of different classes are extremely minimal, and often, the context of the scene should be used to decide. Please find the different classes that may be encountered with examples:

  • Barge

  • Fishing vessel

  • Leisure vessel

  • Merchant vessel

  • Military vessel

  • Passenger vessel

  • Speed vessel

  • Support vessel
