  • Patent number: 11383800
    Abstract: A marine vessel display device includes an imager that images surroundings of a vessel body, an image processor that generates a bird's-eye view image based on images captured by the imager, a display provided in the vessel body and that displays the bird's-eye view image, and a controller. The controller is configured or programmed to perform a control to switch an image displayed on the display from the bird's-eye view image to an object image obtained by imaging in a direction toward an object from the vessel body based on object information.

  • Patent number: 11243539
    Abstract: An imaging system for a ship includes cameras mounted on the ship and spaced apart at a predetermined interval, and a controller that combines peripheral images of the ship captured by the respective cameras to create a simulated bird's eye image. Adjacent ones of the cameras are located at positions and angles so that the peripheral images include a common portion of the ship. The controller performs a calibration process to adjust areas of the peripheral images to be used for the bird's eye image based on a calibration index located at a portion of the ship and included in the common peripheral images.

  • Patent number: 10794708
    Abstract: A server system includes a communicator, a storage, and a controller. The controller is configured or programmed to receive positional information of a watercraft that a user of a wireless communication terminal is aboard and propulsion device information from the wireless communication terminal through the communicator. The propulsion device information indicates a type of a propulsion device on the watercraft. The controller creates cruise trajectory information and stores the created cruise trajectory information in the storage based on the positional information of the watercraft in association with the type of the propulsion device on the watercraft. The controller determines a frequency at which cruise trajectories of the watercraft match the cruise trajectories based on the cruise trajectory information in the storage. The controller creates cruise route information in association with the type of the propulsion device on the watercraft.

  • Patent number: 9598162
    Abstract: In a watercraft, an engine rotational speed sensor detects a rotational speed of an engine. A determining section determines if a prescribed execution condition indicating that a hull body is moving is satisfied. A filter processing section applies a filter process to the engine rotational speed detected by the engine speed sensor to acquire a filtered engine rotational speed. A control section executes a maximum speed limiting control to limit a maximum speed of the watercraft when the prescribed execution condition is satisfied and the filtered engine rotational speed is larger than a prescribed rotational speed threshold value.
