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. An entry control system, comprising:

a scanner configuration including a camera capable of recording simultaneous or near-simultaneous images of a vehicle underside from different angles;

a computer in communication with the scanner configuration, the computer having a touch screen interface;

a database accessible by the computer, the database storing images for a plurality of vehicle undercarriages categorized by at least one vehicle identifier, which can be a vehicle make, model, year, license plate, license number, VIN number, RFID tag, or owner information; and

programming for comparing the database images with at least two images of a vehicle undercarriage comprising images recorded by the camera of the vehicle underside at different angles.

2. The system of claim 1 further including a front view camera capable of receiving above ground images of a vehicle and communicating the images to the computer.

3. The system of claim 1 further including means for automatically searching for and identifying foreign objects on the vehicle underside.

4. The system of claim 1 wherein the scanner configuration includes programming for stitching together video frame images recorded by the camera into a single image.

5. The system of claim 1 further including means for permitting or denying vehicle entry into a facility based upon comparison results produced by the programming.

6. The system of claim 1 wherein the scanner configuration further comprises:

a scanner framework having a front end, a back end and a top surface;

a first mirror arrangement secured to the framework so as to provide a first reflecting surface angled upwardly toward the top surface and toward the framework front end; and

a second mirror arrangement secured to the framework so as to provide a second reflecting surface angled upwardly in a direction facing the framework top surface and the framework back end.

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

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

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

providing means for recording by the camera at least two images of a vehicle underside from different angles at the same time.

8. The method of claim 7 including the further steps of:

categorizing the one or more images according to the vehicle year, make, model and transmission type; and

storing the one or more images in a computer database.

9. The method of claim 8 including the further steps of:

recording simultaneous or near-simultaneous images of a vehicle underside from different angles using the camera; and

comparing at least one stitched frame image comprising the recorded images with one or more stored images to determine one or more identifying characteristics of the vehicle.

10. The method of claim 9 including the further steps of:

identifying the vehicle make and model; and

providing programming for determining whether the vehicle has a different vehicle underside profile from a baseline vehicle underside profile for the identified vehicle type.

11. The method of claim 7 wherein providing the recording means includes the steps of:

providing a first mirror arrangement secured to the framework so as to provide a first reflecting surface angled upwardly toward the top surface and toward the framework front end; and

providing a second mirror arrangement secured to the framework so as to provide a second reflecting surface angled upwardly in a direction facing the framework top surface and the framework back end.

12. A method for establishing records for use in analyzing the underside of a vehicle, comprising the steps of:

recording one or more images of the underside of one or more vehicles using a scanner camera configuration comprising a camera capable of recording simultaneous or near-simultaneous images of a vehicle underside from different angles;

categorizing the one or more images according to the vehicle year, make, model and transmission type; and

storing the one or more images in a computer database.

13. The method of claim 12 wherein the scanner camera configuration further comprises

a scanner framework having a front end, a back end and a top surface;

a first mirror arrangement secured to the framework so as to provide a first reflecting surface angled upwardly toward the top surface and toward the framework front end; and

a second mirror arrangement secured to the framework so as to provide a second reflecting surface angled upwardly in a direction facing the framework top surface and the framework back end.
