    Abstract: A method of verifying a potential detection of a man overboard event recorded as a moving object in a plurality of sequential frames of image data in respect of a duration of a time window comprises receiving (900) ranging track data in respect of the time window. A geometric chord is then identified that intersects a start point and an end point of a path described by a ranging track of the ranging track data. A height of the start point and an angle defined by a convergence of the chord and a vertical are then determined (902, 906). The height and the angle are then compared relative to a boundary line in order to classify (910) the path described by the ranging track in relation to a man overboard event, thereby validating the potential detection.

  • Publication number: 20190122040
    Abstract: A method of verifying a triggered alert in a man overboard detection system comprises: receiving (600) a plurality of sequential frames of image data associated with the triggered alert followed by motion compensating (616) difference frames formed by generating differences (608) between successive frames. A summation of the motion compensated difference frames is then generated (618). The summation image is then analysed (630, 632) and the detection associated therewith is classified (634, 636) in response to identification of a cluster of pixels corresponding to a predetermined size range.
