Abstract

The present specification discloses systems and methods for integrating manifest data for cargo and light vehicles with their X-ray images generated during scanning. Manifest data is automatically imported into the system for each shipment, and helps the security personnel to quickly determine the contents of cargo. In case of a mismatch between cargo contents shown by manifest data and the X-ray images, the cargo may be withheld for further inspection. In one embodiment, the process of analyzing the X-ray image of the cargo in conjunction with the manifest data is automated.

Claims

1. A distributed system for scanning cargo and vehicles, the system comprising:

a service post comprising a checkpoint having at least one X-ray inspection system and at least one server in data communication with the X-ray inspection system, wherein the at least one X-ray inspection system generates a scan image of the vehicles'"'"' contents and comprises an application for importing manifest data of the vehicles'"'"' contents and associating the manifest data with said scan image;

a plurality of regional centers, geographically remote from said service post, comprising a plurality of servers and inspection monitors; and

a routing application, wherein said routing application allocates the scan image from the checkpoint, before said scan image is generated, to at least one of said plurality of regional centers for analysis, wherein said allocation is based upon metadata, transmitted by said plurality of regional centers to said routing application, that is indicative of inspection queue lengths, workload, and contention time in each of said plurality of regional centers, wherein at least one of said plurality of servers in the regional center receives the scan image with the manifest data from the service post based upon said allocation, and wherein said regional center reports to the service post if an alarm condition exists based on an analysis of the scan image and manifest data.

2. The system of claim 1, wherein the scan images and manifest data are analyzed by an operator at one of the plurality of regional centers to determine if the contents match.

3. The system of claim 1, wherein the scan images and manifest data are automatically analyzed by an application at one of the plurality of regional centers to determine if the contents match.

4. The system of claim 2, wherein each X-ray scan image is associated with a unique identifier before transmission from the service post to the regional center.

5. The system of claim 1 further comprising a server that executes an application for allocating images and manifest data from the service post to one of the plurality of regional centers.

6. The system of claim 4, wherein scan images, their associated unique identifiers and manifest data, and results of analyses at the regional center are stored in a database.

7. A method for inspecting cargo and vehicles, comprising:

scanning cargo at a service post, wherein the service post comprises at least one X-ray inspection system and at least one server in data communication with the X-ray inspection system and wherein the at least one X-ray inspection system generates a scan image and comprises an application for importing manifest data and associating said manifest data with said scan image;

receiving at a regional center, geographically remote from said service post, said scan image and manifest data, wherein at least one of a plurality of servers in the regional center receives the scan image with the manifest data from the service post based upon an allocation from a routing application;

at the regional center, obtaining a cargo code from the manifest data;

computing features of the image, wherein said features include attenuation, texture, atomic number and cargo height;

acquiring features associated with said cargo code from a database; and

determining a probability that the cargo matches the manifest data by comparing the computed features with the acquired features associated with the cargo code.

8. The method of claim 7, further comprising determining whether a threat item or alarm condition is present.

9. The method of claim 7, further comprising reporting the threat item or alarm condition to the service post.

10. The method of claim 7, wherein each scan image is associated with a unique identifier before transmission from the service post to the regional center.

11. The method of claim 10, wherein the scan images, their associated unique identifiers and manifest data, and results of analyses are stored in a database.

12. The method of claim 7 further comprising segregating the generated scan image according to cargo types, if the cargo is associated with more than one cargo code.

13. The method of claim 12, wherein each segregated part of the image is compared to historically stored images associated with the corresponding cargo code.

14. The method of claim 12, wherein the step of comparing said scan image to historically stored images is performed automatically.
