Abstract

Systems and methods for threat detection include receiving data regarding a vehicle currently detected in the area. One or more characteristics of the currently detected vehicle may be compared to a model of previously detected vehicles. Based on the comparison, the one or more characteristics of the currently detected vehicle may be determined to be anomalous.

Claims

1. A method of automatically monitoring traffic in an area, the method comprising:

automatically receiving, at processing electronics, vehicle data from a sensor in response to the sensor currently detecting a vehicle in an area, the vehicle data regarding the currently detected vehicle and including one or more characteristics of the currently detected vehicle;

classifying, by the processing electronics, the vehicle data and historical sensor data, the historical sensor data indicative of a plurality of heterogeneous vehicles previously detected in the area, the historical sensor data classified into at least two groups based on one or more characteristics of the previously detected vehicles, each group including at least two heterogeneous vehicles;

generating, by the processing electronics, at least one model for each of the at least two groups, the at least one model for each group representing typical characteristics of the plurality of heterogeneous vehicles previously detected in the area, the at least one model based on the one or more characteristics of the plurality of heterogeneous vehicles previously detected in the area;

selecting, by the processing electronics, a model from the at least two models based in part on the classification of the vehicle data;

comparing, by the processing electronics, the one or more characteristics of the currently detected vehicle to the selected model;

determining, by the processing electronics, the one or more characteristics of the currently detected vehicle to be anomalous based on a comparison of the one or more characteristics of the currently detected vehicle to the selected model; and

providing, by the processing electronics, display data to a display system that causes the display system to display an indication of the currently detected vehicle having one or more anomalous characteristics.

2. The method of claim 1, further comprising:

receiving, at the processing electronics, historical sensor data indicative of the one or more characteristics of the vehicles previously detected in the area; and

generating the model using the historical sensor data.

3. The method of claim 2, wherein the model is a regression model.

4. The method of claim 2, wherein the model is generated by determining a centroid of the one or more characteristics of the vehicles previously detected in the area.

5. The method of claim 1, wherein the one or more characteristics of the currently detected vehicle comprise one or more of:

a size of the vehicle, a location of the vehicle, a speed of the vehicle, an altitude of the vehicle, or a national affiliation of the vehicle.

6. The method of claim 1, wherein the indication comprises a display screen excluding currently detected vehicles that are not determined to be anomalous.

7. A system for automatically monitoring traffic in an area comprising processing electronics configured to:

automatically receive vehicle data from a sensor in response to the sensor currently detecting a vehicle in an area, the vehicle data regarding the currently detected vehicle and including one or more characteristics of the currently detected vehicle;

classify the vehicle data and historical sensor data, the historical sensor data indicative of a plurality of heterogeneous vehicles previously detected in the area, the historical sensor data classified into at least two groups based on one or more characteristics of the previously detected vehicles, each group including at least two heterogeneous vehicles;

generate at least one predictive model for each of the at least two groups, the at least one predictive model for each group representing an expected traffic pattern in the area, the predictive model based on one or more characteristics of the plurality of heterogeneous vehicles previously detected in the area;

select a predictive model from the at least two models based in part on the classification of the vehicle data;

compare the one or more characteristics of the currently detected vehicle to the selected predictive model;

determine the one or more characteristics of the currently detected vehicle to be anomalous based on a comparison of the one or more characteristics of the currently detected vehicle to the selected predictive model; and

provide display data to a display system that causes the display system to display an indication of the currently detected vehicle having one or more anomalous characteristics.

8. The system of claim 7, wherein the processing electronics are further configured to:

receive historical sensor data indicative of the one or more characteristics of the vehicles previously detected in the area; and

generate the predictive model using the historical sensor data.

9. The system of claim 8, wherein the predictive model is a regression model.

10. The system of claim 8, wherein the predictive model is generated by determining a centroid of the one or more characteristics of the vehicles previously detected in the area.

11. The system of claim 7, wherein the one or more characteristics of the currently detected vehicle comprise one or more of:

a size of the vehicle, a shape of the vehicle, an altitude of the vehicle, or a national affiliation of the vehicle.

12. The system of claim 7, wherein the indication comprises a display screen excluding currently detected vehicles that are not determined to be anomalous.

13. A non-transitory computer-readable storage medium having instructions stored therein, the instructions being executable by a processor to cause the processor to perform operations, the operations comprising:

automatically receiving vehicle data from a sensor in response to the sensor currently detecting a vehicle in an area, the vehicle data regarding the currently detected vehicle and including one or more characteristics of the currently detected vehicle;

classifying the vehicle data and historical sensor data, the historical sensor data indicative of a plurality of heterogeneous vehicles previously detected in the area, the historical sensor data classified into at least two groups based on one or more characteristics of the previously detected vehicles, each group including at least two heterogeneous vehicles;

selecting a model from the at least two models based in part on the classification of the vehicle data;

comparing the one or more characteristics of the currently detected vehicle to the selected model;

determining the one or more characteristics of the currently detected vehicle to be anomalous based on a comparison of the one or more characteristics of the currently detected vehicle to the selected model; and

providing display data to a display system that causes the display system to display an indication of the currently detected vehicle having one or more anomalous characteristics;

wherein the currently detected vehicle and the plurality of heterogeneous vehicles previously detected in the area are maritime vehicles.

14. The non-transitory computer-readable storage medium of claim 13, wherein the operations further comprise:

receiving historical sensor data indicative of the one or more characteristics of the vehicle previously detected in the area; and

generating the model using the historical sensor data.
