Abstract:
1. A method of distinguishing false positives from threats in a space, the method comprising: (a) collecting a first scan of the space during a first time interval, comprising (b) collecting a second scan of the space during a second time interval, comprising repeating steps (a)(i)-(a)(v) above during the second time interval to generate a second three-dimensional map of the space; (c) comparing the first three-dimensional map to the second three-dimensional map to determine a change in the space; (d) identifying a potential security threat based on the change in the space; and (e) determining, based on the change in the space, if the potential security threat is a false positive based on a rate of movement, a height, and a location of the threat within the space.
