1. A detection system for detecting a presence of a threat object on a person comprising:
- a gate defining a detection area;
at least one camera positioned proximate to said gate, wherein said at least one camera is adapted to capture a plurality of frames and wherein each of said plurality of frames is indicative of a position of the person as the person moves through said detection area;
a plurality of magnetic field generators and a plurality of magnetic field detectors positioned within said gate and adapted to generate a plurality of electromagnetic images of said person and the threat object passing through said detection area;
anda processor adapted to determine which frame from said plurality of frames was recorded when an electromagnetic image from said plurality of electromagnetic images was generated, to analyze said frame to identify which parts of the person are within said electromagnetic image, and determine how far said parts were displaced relative to a reference position.

Abstract
A detection system comprising a plurality of magnetic field generators and a plurality of magnetic field detectors located adjacent to a detection area, and a control system arranged to generate magnetic field using the generators, and, for each of the generators, to make measurements of the magnetic field generated using each of the detectors, and processing means arranged to process the measurements to generate a data set characterizing the detection area.

13. A method of analyzing an object in possession of a person comprising,
providing a gate defining a detection area; -
providing at least one camera positioned proximate to said gate, wherein said at least one camera is adapted to capture a plurality of frames and wherein each of said plurality of frames is indicative of a position of the object as the person moves through said detection area; providing a plurality of magnetic field generators and a plurality of magnetic field detectors positioned within said gate to generate a plurality of electromagnetic images of said person and the threat object passing through said detection area; using a processor, determining which frame from said plurality of frames was recorded when an electromagnetic image from said plurality of electromagnetic images was generated; using said processor, analyzing said frame to identify which parts of the person are within said electromagnetic image; using said processor, determining a displacement of said parts relative to a reference position; and correcting for said displacement by shifting one or more of said parts to said reference position. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
