Claim:
1. A method of detecting a man overboard event on a structure above a waterline, the method comprising the steps of: providing first and second imaging devices, each having a view volume, contemporaneously processing first and second video streams of a common detection volume, the common detection volume characterized as a three-dimensional space disposed above the waterline, along the structure, and formed from an overlap of the view volumes of the first and second imaging devices; contemporaneously monitoring with the first and second imaging devices a falling object falling along a trajectory through the common detection volume in the first and second video streams; determining, from the first and second video streams, corresponding first and second characteristics, respectively, of the falling object as the object falls along the trajectory through the common detection volume streams, respectively; and comparing the first and second characteristics from the first and second video streams and identifying a man overboard event in response to a conforming comparison.
