Abstract
A method of determining the draft of a vessel comprising the steps of: measuring the draft of the vessel using at least one optical imaging device to provide optical draft measurement data; measuring the draft of the vessel using elevation data provided by at least one GNSS or GPS device so as to provide elevation draft measurement data; and using the elevation draft measurement data and the optical draft measurement data to determine the draft of the vessel.
Claims27
A method of determining the draft of a vessel comprising the steps of:
- measuring the draft of the vessel using at least one optical imaging device to provide optical draft measurement data of the draft of the vessel based on an automatic detection of the position of at least one draft mark on a hull of the vessel;
- using the optical draft measurement data to initialise elevation data provided by at least one GNSS or GPS device so as to provide elevation draft measurement data of the draft of the vessel;
- and
- using the elevation draft measurement data to provide at least one measurement of the draft of the vessel subsequent to the step of initialising the elevation draft measurement data.

A system for determining the draft of a vessel, the system comprising:
- at least one optical imaging device located on a wharf, and at least one GNSS or GPS device;
- the system being adapted to:
- measure the draft of the vessel using the at least one optical imaging device to provide optical draft measurement data based on an automatic detection of the position of at least one draft mark on a hull of the vessel;
- use the optical draft measurement data to initialise elevation draft measurement data provided by the at least one GNSS or GPS device;
- and
- use elevation draft measurement data to provide at least one measurement of the draft of the vessel subsequent to the step of initialising the elevation draft measurement data.

A method of determining the draft of a vessel using at least one optical imaging device comprising:
- operating the optical imaging device to capture an optical image of at least one draft mark on a hull of the vessel;
- performing optical character recognition (OCR) processing of the optical image to provide OCR data for the at least one draft mark;
- determining a location in cartesian space of the at least one draft mark;
- using the OCR data and the location in cartesian space of the at least one draft mark in the determination of optical draft measurement data for the draft of the vessel.
