FIELD: physics, control.SUBSTANCE: invention relates to a system and a method for detecting electronic article surveillance (EAS) marker shielding using EAS, metal detection and video analysis subsystems communicatively connected to a system controller. The EAS subsystem detects EAS markers within a detection zone. The metal detection subsystem detects metallic objects within the detection zone. The video analysis subsystem captures a video image of the metallic object. The system controller determines a probable classification for the metallic object and calculates a confidence weight for the probable classification. If the metallic object is identified as EAS marker shielding according to the probable classification and the corresponding confidence weight, an alarm signal is generated.EFFECT: preventing generation of false alarm signals.20 cl, 9 dwg |
