Abstract
The present specification discloses a covet mobile inspection vehicle with a backscatter X-ray scanning system that has an X-ray source and detectors for obtaining a radiographic image of an object outside the vehicle. The systems preferably include at least one sensor for determining a distance front at least one of the detectors to points on the surface of the object being scanned, a processor for processing the obtained radiographic image by using the determined distance of the object to obtain an atomic number of each material contained in the object, and one or more sensors to obtain surveillance data from a predefined area surrounding the vehicle.
Claims30
An inspection system comprising:
- a first sensor, wherein the first sensor is at least one of a laser, a GPS device, a video camera, an X-ray scanner, an infrared imaging system, a radio frequency antenna, a wide band antenna, a chemical sensor, a license plate recognition system, or an audio microphone and wherein the first sensor is configured to generate first data;
- a second sensor, wherein the second sensor is at least one of the laser, the GPS device, the video camera, the X-ray scanner, the infrared imaging system, the radio frequency antenna, the wide band antenna, the chemical sensor, the license plate recognition system, or the audio microphone, wherein the second sensor is different from the first sensor and wherein the second sensor is configured to generate second data;
- and
- a processor configured to receive the first data from the first sensor and the second data from the second sensor, to process the first data and the second data in order to determine a degree of correlation and a presence of one or more risks associated with the first data and the second data, and, based on determining the presence of the one or more risks, to generate a threat alarm.
