Abstract
An autonomous cruising system is capable of discriminating a port sign and a starboard sign without depending on a position of a ship. The system includes processing circuitry that acquires an image generated by a camera installed in a ship. The processing circuitry identifies whether a mode of a lateral buoy included in the image is either a first mode or a second mode. The processing circuitry determines a country to which a position of the ship detected by a position detector belongs. The processing circuitry determines whether description of a sign of the lateral buoy is the port sign or the starboard sign, from the mode of the lateral buoy and the determined country, based on a given correspondence relationship indicative of whether each of the first mode and the second mode corresponds to either one of the port sign and the starboard sign in each country.
