1. A vehicle monitoring system configured to detect and localize an anomaly in or on a vehicle, the anomaly emitting an invisible indicator in the form of a magnetic field or radiation, the system comprising:
an under vehicle module for positioning on a ground over which the vehicle may pass to monitor the vehicle from below, the under vehicle module housing a detector and a camera that are arranged to monitor an underside face of the vehicle;
wherein the detector is configured to detect the invisible indicator originating from or emitted by the anomaly and generate a detection signal associated with the invisible indicator;
wherein the camera is configured to capture an image of the underside face of the vehicle viewed from below the vehicle in the form of a scan that is time-gated or synchronized with the detection signal as the vehicle passes over the under vehicle module; and
a controller configured to process the detection signal generated by the detector and the image of the vehicle captured by the camera, and to, based on processing of the image and the detection signal as a data grid, determine whether the detection signal exceeds a threshold and generate a visualization of the detection signal overlaid onto the image of the vehicle indicating a location in the data grid where the detection signal exceeds the threshold to allow localization of the anomaly in or on the vehicle.
