Abstract

The present invention provides an entry control device, system and method which can recognize a vehicle by its undercarriage image only. The present invention compares a new vehicle undercarriage image with those stored in a reference database to facilitate the automatic search of a vehicle'"'"'s undercarriage. The present invention can compare the new undercarriage image to the same or similar undercarriage image previously entered in the reference database, highlighting any anomalies such as, for example, foreign objects, explosives, drugs, paraphernalia and other illegal and/or harmful substances and devices.

Claims

1. A method for vehicle access control, comprising the steps of:

providing a scanner framework having a front end and a back end;

securing at least one mirror to the framework;

providing a scanner camera having a lens facing at least a portion of either the framework front end or the framework back end;

recording one or more images of the underside of a vehicle by the camera using the at least one mirror; and

based on the one or more recorded images of the underside of the vehicle, determining the make and model of the vehicle.

2. The method of claim 1 wherein the scanner camera is secured to the framework between the front and back ends of the framework.

3. The method of claim 1 wherein the scanner framework is positioned below ground level.

4. The method of claim 1 wherein the step of determining the make and model of the vehicle is performed exclusively on the basis of the one or more recorded images of the underside of the vehicle.

5. The method of claim 1 wherein the at least one mirror includes a first mirror and a second mirror.

6. The method of claim 5 wherein the first mirror is secured at or near the front end of the scanner framework, and the second mirror is secured at or near a location between the framework front and back ends.

7. The method of claim 5 wherein the camera is adapted to record images of the vehicle underside at different angles at substantially the same time using the pair of mirrors.

8. The method of claim 1 including the step of securing the camera to the framework.

9. The method of claim 5 including the step of securing the camera to the framework such that a portion of the lens faces the first mirror and a portion of the lens faces the second mirror.

10. The method of claim 1 wherein the scanner framework includes a top surface, and wherein the scanner camera is secured to the scanner framework such that the camera lens is angled downwardly away from the framework top surface.

11. An entry control system, comprising:

a scanner framework having a front end and a back end;

at least one mirror secured to the scanner framework;

a scanner camera having a lens facing at least a portion of either the framework front end or the framework back end, wherein the camera is adapted to record one or more images of a vehicle underside using the at least one mirror;

at least one data storage device operable to store computer-readable instructions;

at least one computer processor operable to execute the computer-readable instructions; and

a set of computer-readable instructions operable to determine the make and model of the vehicle based on the one or more recorded images.

12. The system of claim 11 wherein the scanner camera is secured to the framework between the front and back ends of the framework.

13. The system of claim 11 wherein the scanner framework is positioned below ground level.

14. The system of claim 11 wherein the computer readable instructions are adapted to determine the make and model of the vehicle based exclusively on the one or more recorded images of the underside of the vehicle.

15. The system of claim 11 wherein the at least one mirror includes a first mirror and a second mirror.

16. The system of claim 15 wherein the first mirror is secured at or near the front end of the scanner framework, and the second mirror is secured at or near a location between the framework front and back ends.

17. The system of claim 15 wherein the camera is adapted to record images of the vehicle underside at different angles at substantially the same time using the pair of mirrors.

18. The system of claim 11 including the step of securing the camera to the framework.

19. The system of claim 15 including the step of securing the camera to the framework such that a portion of the lens faces the first mirror and a portion of the lens faces the second mirror.

20. The system of claim 11 wherein the scanner framework includes a top surface, and wherein the scanner camera is secured to the scanner framework such that the camera lens is angled downwardly away from the framework top surface.
