Abstract: The invention relates to a system for locating an object and optionally determining the dimension thereof in a specified area/space, comprising a plurality of cameras which capture the area from different locations, wherein a common detection region is provided for each of at least two cameras which are arranged at different locations; means for marking an object detected simultaneously by at least two cameras in the images captured by the respective cameras; and means for determining the position of the object marked in the images of the cameras by calculating the respective line of position between each camera and the object detected by each camera and by calculating the coordinates of the object at the intersection of the lines of position in a coordinate system mapping the area.

Abstract: A system for detecting a man-overboard event, comprising a plurality of first computing units having at least one optical sensor with a predetermined detection range and a second computing unit connected to the plurality of computing units, characterized in that each first computing unit is designed, independently of the others, to evaluate the data sensed by the at least one optical sensor of the respective first computing unit to determine whether a man-overboard event is present on the basis of these data and, when a man-overboard event (event) is present, to report this to the second computing unit, wherein the second computing unit is designed to output an alarm and/or a control command to carry out a man-overboard manoeuvre.
