Ships specialized for sea routes which link ports in Japan (coastal vessels) transport one third or over 330 million tons of the total amount of domestic freight, a huge volume of goods. More than 5,400 coastal vessels navigate Japan’s coast day and night. Information such as current location, course and speed of the ships being navigated is constantly obtained and understood via a system called an automatic identification system (AIS). By adding images to this system, the condition of ships and their routes can be more accurately understood. Ships have a total length of dozens of meters, and high-level zoom performance is required of a camera which must accurately check conditions of the area of operation, conditions of loading/unloading and other work situations, and conditions at departure and arrival time.
At AIS Live Japan LLP, which provides an AIS service for coastal vessels, an image transmission service that employs network cameras and uses a mobile network linking the coast and the ship was started in March 2011, in cooperation with Marine Japan.
After the introduction of the Axis network camera, the following results were gained.
