Abstract

A method 10 of verifying a traffic violation image and includes the step of automatically sensing 12 whether or not a vehicle commits a traffic violation, the step of automatically capturing 14 an image which shows a vehicle committing a traffic violation if it is sensed 12 that the vehicle has committed a traffic violation, the step of obtaining 16 verification data which verifies that the step of sensing 12 is accurate within acceptable limits, and the step of automatically combining 18 the obtained verification data with the captured traffic violation image to provide proof of the accurate sensing of the traffic violation. Also provided is an associated system.

Claims

1. A system for verifying a traffic violation image, which system includes:

a sensor for automatically sensing whether or not a vehicle commits a traffic violation;

a camera arranged in communication with the sensor which camera is configured to automatically capture an image of a vehicle committing a traffic violation if it is sensed that the vehicle has committed a traffic violation; and

a processor arranged in communication with the camera which processor configured to obtain calibration data which verifies a calibration history of the sensor and/or the camera in order to verify that the sensor and/or the camera senses accurately within acceptable limits, and to automatically incorporate the obtained calibration data into the captured traffic violation image to provide proof of the accurate sensing and/or capturing of the traffic violation.

2. The system as claimed in claim 1, wherein the processor is configured to obtain the calibration data by comparing operational parameters of the camera and/or sensor to a standard or measurements made by a more accurate instrument for the purpose of detecting, reporting, and eliminating by adjustment any errors in the sensor and/or camera tested.

3. The system as claimed in claim 2, wherein the operational parameters include ambient conditions of the system.

4. The system as claimed in claim 2, wherein the operational parameters include operating levels of components comprising the system.

5. The system as claimed in claim 2, wherein the operational parameters include a unique identifying number of an engineer who installed the system.

6. The system as claimed in claim 2, wherein the operational parameters include identification numbers of components comprising the system.

7. The system as claimed in claim 2, wherein the operational parameters include a preprogrammed speed limit which, when exceeded by a vehicle sensed by the sensor, triggers the camera which captures the traffic violation image.

8. The system as claimed in claim 2, wherein tie operational parameters include a grace time period before the camera is triggered by the sensor.

9. The system as claimed in claim 2, wherein the processor obtains the operational parameters as real-time values.

10. The system as claimed in claim 2, wherein the operational parameters include a geographic location where the image is captured.

11. The system as claimed in claim 10, wherein the geographic location is supplied by a Global Positioning System (GPS).

12. The system as claimed in claim 1, wherein the processor obtains the calibration data at the same time that the camera captures the traffic violation image.

13. The system as claimed in claim 1, wherein the processor incorporates the calibration data with the image by digitally signing and encrypting the calibration data together with the violation image.

14. The system as claimed in claim 1, wherein the processor facilitates the transmission of the verified violation image to a remote location.

15. A method of verifying a traffic violation image which method includes the following steps

automatically sensing whether or not a vehicle commits a traffic violation;

automatically capturing an image which shows the vehicle committing a traffic violation if it is sensed that the vehicle has committed a traffic violation;

obtaining calibration data which verifies a calibration history of equipment used to sense and/or capture the traffic violation in order to verify that the steps of sensing and/or capturing are accurate within acceptable limits; and

automatically incorporating the obtained calibration data into the captured traffic violation image to provide proof of the accurate sensing and/or capturing of the traffic violation.

16. The method as claimed in claim 15, wherein the calibration data is obtained by comparing operational parameters of the equipment to a standard or measurements made by a more accurate instrument for the purpose of detecting, reporting, and eliminating by adjustment any errors in the equipment tested.

17. The method as claimed in claim 16, wherein the operational parameters include ambient conditions of the equipment.

18. The method as claimed in claim 16, wherein the operational parameters include operating levels of components comprising the equipment.

19. The method as claimed in claim 16, wherein the operational parameters represent real-time values obtained at the same time that the image is captured.

20. The method as claimed in claim 15, wherein the step of incorporating the calibration data includes digitally signing and encrypting the calibration data together with a digital violation image.
