A method and a device for monitoring a region (R) in which a carrier (100) is located, which device comprises a display unit displaying a polar plot (10) having a center symbolizing the current position of the carrier (100) and in which there is placed a first moving-body symbol (1, 2, 3) representing the current position of the moving body (101, 102, 103); the polar plot (10) being surrounded by an annular band (20) of width (l) representing a predetermined monitoring duration and containing second moving-body symbols (1′, 2′, 3′) representative of successive angle readings of the path of said moving body (101, 102, 103).

A ship maneuver supporting device capable of displaying a collision risk zone which matches navigation feel of a ship operator with reduced calculation load, is provided. The ship maneuver supporting device 1 includes processing circuitry (11, 21, 31, 41). The processing circuitry calculates a collision risk value for determining whether a collision risk zone that is a zone where a possibility of a collision between a first ship and a second ship will occur in the future is high is to be displayed, based on a separating distance between the position of the second ship estimated at a plurality of future time points and the position of the first ship estimated corresponding thereto, in consideration of a physical size of at least one of the first ship and the second ship. Further, the processing circuitry generate display data for displaying the collision risk zone at the estimated position of the second ship, based on the determination using the collision risk value.

The present disclosure is directed to providing a monitoring device that can improve the accuracy in tracking ships. A monitoring device (10) according to the present disclosure includes a position information acquiring unit (11) configured to acquire position information of an object to be tracked; an estimating unit (12) configured to estimate a position of the object to be tracked displayed in an image captured of a predetermined region; and an information generating unit (13) configured to generate path information of the object to be tracked by supplementing, based on an estimated position of the object to be tracked, the position of the object to be tracked held between the position indicated by the position information acquired at a first timing and the position indicated by the position information acquired at a second timing later than the first timing.

A data processing apparatus is provided, which includes processing circuitry. The processing circuitry is configured to acquire a data set from target detected by a detection apparatus, perform rendering of the data set, and generate a plurality of views arranged on a screen. Each view of the plurality of views includes a plurality of pixels. Each pixel included in the plurality of views is associated with a plurality of pieces of information including a first information displayed on the screen and a second information that indicates a view among the plurality of views to which the pixel belongs.

A driver-assist system for a marine vessel may include a camera operable to obtain data comprising images of a view of the camera, and a data processor. The data processor may be programmed to distinguish between portions of the view representing water and/or sky a portion of the view representing an object. The data processor may be programmed to detect an object by causing object detectors to search for objects in respective different subregions of the view. The data processor may be programmed to detect a boat in the view. The data processor may be programmed to cause the marine vessel to follow a detected boat.

Aspects of the invention provide improvements to analyze data collected by a radar system. One of the systems includes a phased array module configured to transmit a sequence of pulses to an environment according to a pre-determined pattern. A data analysis system constructs an image based on returned signals from a single point received by the phased array module, and determines one or more characteristics of a target object in the environment based on the image constructed from the returned signals from the single point.

An electric vessel includes a drive motor to rotate a propeller; a battery module to supply a voltage; an inverter to convert a DC voltage of the battery module into an AC voltage to drive the drive motor; a battery management system (BMS); an electronic control unit (ECU) including a vessel control unit to control the BMS, the inverter, and the drive motor in order to operate the vessel; and an operation unit to transmit an operation signal to the ECU according to a driver's operation.
