Abstract

The present application is directed toward cargo scanning systems having scanners, each arranged to scan a respective object and generate a set of scan data, processors arranged to process each set of scan data to determine whether it meets a predetermined threat condition, workstations, and data management system arranged to direct data that meets the threat condition to one of the workstations for analysis.

Claims

1. A cargo scanning system, wherein the cargo is positioned inside a plurality of containers, comprising:

a plurality of scanners each arranged to scan at least one of the plurality of containers, generate sets of scan data, and communicate the sets of scan data to a network;

a central storage array in data communication with the network and configured to receive the sets of scan data from each of the plurality of scanners;

one or more workstations in data communication with the network, wherein each of the one or more workstations is configured to receive a user input;

an imaging device configured to capture images of characters associated with the at least one of the plurality of containers;

an imaging processor configured to generate optical character recognition data indicative of the characters associated with the at least one of the plurality of containers;

a job dispatcher in data communication with the network and configured to execute a process for automatically allocating the sets of scan data to at least one of the one or more workstations for analysis, to make the sets of scan data available to the one of the one or more workstations, to receive and direct data indicative of the characters associated with the at least one of the plurality of containers and manifest information related to the cargo and to generate a hybrid set of scan data by combining a threat object image from a library of threat object images with one of the sets of scan data;

a cargo movement control means arranged to control movement of the at least one of the plurality of containers; and

an area wherein the cargo movement control means is arranged to control movement of the at least one of the plurality of containers into or within the area if the user input allocates the at least one of the plurality of containers to one of a plurality of predetermined threat categories.

2. The system according to claim 1, wherein the job dispatcher is arranged to control a supply of data from the sets of scan data to a processing means, wherein the processing means is configured to process each of the sets of scan data to determine whether portions of the sets of scan data meets one of the plurality of predetermined threat categories.

3. The system according to claim 2 wherein the processing means is arranged to receive at least one set of secondary data associated with the at least one of the plurality of containers and to process the secondary data as well as the sets of scan data to determine whether a threat condition is met.

4. The system according to claim 3 wherein the secondary data comprises at least one of the following:

weighbridge data, chemical detector data, gamma ray detector data or neutron sensor data.

5. The system according to claim 2 wherein the processing means is further configured to execute a process for automatically determining whether the at least one of the plurality of containers associated with each of the sets of scan data are cleared and to transfer a fraction of the sets of scan data associated with the at least one of the plurality of containers that are cleared to the one or more workstations.

6. The system according to claim 1 wherein the job dispatcher is arranged to transmit the sets of scan data to the one or more workstations.

7. The system according to claim 1 wherein the user input at each of the one or more workstations is configured to enable a user to provide an input allocating the sets of scan data to one of the plurality of predetermined threat categories.

8. The system according to claim 1 further comprising a holding bay wherein the cargo movement control means is arranged to hold the at least one of the plurality of containers in the holding bay in response to the at least one of the plurality of containers being allocated to one of the plurality of predetermined threat categories.

9. The system according to claim 8 wherein the cargo movement control means is arranged to cause the at least one of the plurality of containers to bypass the holding bay if the at least one of the plurality of containers does not meet a threat condition.

10. The system according to claim 1 wherein the cargo movement control means is arranged to control movement of the at least one of the plurality of containers so as to bypass the area if the user input does not allocate it to one of the plurality of the predetermined threat categories.

11. The system according to claim 1 wherein a data management means is arranged to generate a profile of an accuracy of the user'"'"'s allocation of the sets of scan data to the one of the plurality of predetermined threat categories.

12. The system according to claim 1 wherein the threat object image is combined with the one of the sets of scan data by superimposing the threat object image onto an image corresponding to the one of the sets of scan data.

13. The system according to claim 1 wherein the one of the sets of scan data combined with the threat object image corresponds to an image of cargo without a threat.

14. The system according to claim 1 wherein the one or more workstations is further configured to receive a user input that identifies the threat object image in the hybrid set of scan data as being a threat.

15. The system according to claim 14 wherein the job dispatcher is configured to receive the user input identifying the threat object in the hybrid set of scan data as being a threat and send a notification to the one or more workstation that a known threat had been inserted into the one of the sets of scan data.

16. The system according to claim 14 wherein the job dispatcher is further configured to store in the central storage array a record of whether an operator of the one or more workstations correctly identified the threat object image in the hybrid set of scan data as being a threat.

17. The system according to claim 1 wherein a type of the threat object image combined with the one of the sets of scan data is dependent upon an identity of an operator of one of the one or more workstations.
