[Problem] To provide a movement route generation system capable of safely and efficiently generating a movement route for navigating while avoiding obstacles. [Solution] The movement route generation system according to the present disclosure generates movement route information to a target position on the basis of ship information relating to a ship, obstacle information relating to an obstacle, and target position information relating to the target position. The ship information includes current position information of the ship and ship speed information. The obstacle information includes information on the position and size of the obstacle. The movement route information includes time information on the time when the ship moves on the movement route.

[Problem] To provide an information processing system to assist in safely and efficiently navigating while avoiding obstacles. [Solution] An information processing system according to the present disclosure comprises a control unit that performs information processing to assist in navigating to a destination while avoiding obstacles. This control unit performs a parameter determination process for determining a parameter relating to a distance that a host ship is to keep from each obstacle on or in water when the host ship avoids the obstacle, on the basis of obstacle information including position information and size information of the obstacle.

[Problem] To provide an obstacle estimation system for improving safety of a ship by improving obstacle estimation accuracy. [Solution] An obstacle estimation system according to the present disclosure includes a plurality of data acquisition means and a control unit executing information processing and estimates information on an obstacle when a ship navigates. The control unit executes: ship information estimation processing for estimating ship position information and ship orientation information on the basis of first data acquired from at least one of the data acquisition means; ship information correction processing for correcting the ship position information and the ship orientation information on the basis of second data acquired from at least one of the data acquisition means; obstacle information estimation processing for estimating the position and size of an obstacle on the basis of the ship position information and the ship orientation information corrected in the ship information correction processing and third data acquired from at least one of the data acquisition means; and output information generation processing for generating output information based on information on the position and size of the obstacle estimated in the obstacle information estimation processing.
