摘要： In some aspects, a safety system may be configured to receive vehicle position data indicating a position of a vehicle, determine a first lane segment in a lane coordinate system based on the vehicle position data, the first lane segment being a lane segment in which the vehicle is located, determine a relevant set of lane segments based on a safety-range from the first lane segment, determine or receive obstacle position data indicating a second lane segment in the lane coordinate system, the second lane segment being a lane segment in which an obstacle is located, and classify the obstacle either as a non-relevant obstacle in the case that the second lane segment is not included in the relevant set of lane segments, or as a relevant obstacle in the case that the second lane segment is included in the relevant set of lane segments.

摘要： The present disclosure relates to a method for determining an action for collision avoidance in a craft. The method (100) comprises obtaining (110) object data comprising three-dimensional object data points (420); obtaining (120) state data of the craft (260); determining (140) at least one set of manoeuvre paths (410a,b,c) for the craft (260) based on the obtained craft state data; determining (150) a set of distance thresholds (421) for the three-dimensional object data points (420) based on the object data; comparing (160) each set of manoeuvre paths (410a,b,c) with the object data and the set of distance thresholds (421), wherein the set of manoeuvre paths (410a,b,c) is identified as a colliding set of manoeuvre paths (410a,b,c) when each path of the set of manoeuvre paths (410a,b,c) is at least partially within the corresponding distance threshold (421) of at least one three-dimensional object data point (420); and determining (170) an action upon identification of at least one colliding set of manoeuvre paths (410a,b,c).

摘要： A control system for boats includes a direction control system of a propulsion unit having a directional control member, and an acceleration/deceleration control system of the propulsion unit having an acceleration/deceleration control member. The directional control member activates a directional unit that generates directional control signals, which set an orientation of the propulsion unit, and the acceleration/deceleration control member activates an acceleration/deceleration unit that generates acceleration/deceleration control signals, which set at least a number of revolutions of the propulsion unit. The control system further includes a display unit provided with a screen, and a camera having a control system that provides images of areas or zones that cannot be observed by an operator of the control system while steering the boat, so as to enable driving the acceleration/deceleration unit and/or the directional unit according to a content of those images.

摘要： Disclosed is a ship identity recognition method based on the fusion of AIS data and video data, comprising: collecting a ship sample to train a ship target classifier; performing, using the ship target classifier, ship target detection on a video frame collected by a gimbal camera; performing a comparison with a recognized ship library to filter a recognized ship; acquiring AIS data and filtering same across time and spatial scales; predicting the current position of an AIS target using a linear extrapolation method and converting the current position to an image coordinate system; performing position matching between a target to be matched and the converted AIS target; and performing feature extraction on the successfully matched target and storing the extracted feature, together with ship identity information, into the recognized ship library. Experimental results show that the present invention can quickly and accurately extract a surveillance video and perform identity recognition on the ship target, effectively reduces labor costs, and has a broad application prospect in the fields such as ship transportation and port management.

摘要： An apparatus for detecting a traffic participant includes a first detection device for detecting the traffic participant in a first detection zone. The first detection device is configured to repeatedly detect the first detection zone and to detect an entering of a traffic participant in the first detection zone, and/or to detect the traffic participant in an angular section in an extended first detection zone beyond the first detection zone according to an instruction. The apparatus also includes a second detection device that detects the traffic participant in a second detection zone, and is adapted to provide data required for instruction about the traffic participant in response to the detection of the traffic participant and to forward it to the first detection device for instruction. This way, the traffic participant may be detected by the first detection device before entering the first detection zone.

摘要： A method of controlling a propulsion system on a marine vessel includes receiving proximity measurements describing locations of one or more objects with respect to the marine vessel, receiving a command vector instructing magnitude and direction for propulsion of the marine vessel with respect to a point of navigation for the marine vessel, and then determining a funnel boundary based on the command vector. An object is identified based on the proximity measurements and determined to be within the funnel boundary, and then a propulsion adjustment command is calculated based on the command vector and an angle of the object with respect to the point of navigation. At least one propulsion device is then controlled based on the propulsion adjustment command in order to avoid the object.
