Abstract

Embodiments of the present invention disclose a system and method of collision measurement for a vehicle. According to one embodiment, a plurality of photonic crystals configured to produce a color change state are distributed on an area of the vehicle. Furthermore, a location tag is also positioned on the vehicle for providing mapping data relating to the location of the photonic crystals along said vehicle. Upon receiving external crash impact, a measurement of force is computed based on the color change state of at least one photonic crystal caused by the crash impact.

Claims

1. A collision measurement system for a vehicle comprising:

a plurality of photonic crystals distributed on an area of the vehicle and configured to produce a color change state;

at least one location tag positioned on the vehicle and configured to store and provide mapping data relating to a location of the photonic crystals on the vehicle,

wherein upon receiving external impact, a measurement of force is computed based on the color change state of at least one photonic crystal caused by the said impact.

2. The system of claim 1, further comprising:

an imaging device configured to capture the color change state crystal associated with at least one photonic crystal; and

a reader device configured to detect the mapping data associated with location tag.

3. The system of claim 2, further comprising:

a processing unit configured to analyze the crystal location data and color change state of the plurality of photonic crystals in order to generate a stress map that indicates the distribution of forces over the vehicle.

4. The system of claim 1, wherein the vehicle is an automobile, motorcycle, aircraft, or watercraft device.

5. The system of claim 1, wherein the photonic crystals are only distributed on high probability impact areas.

6. The system of claim 1, wherein the photonic crystals are distributed over the entire body of the vehicle.

7. The system of claim 1, wherein the location tag is an RFID element.

8. The system of claim 1, wherein the location tag is a bar code embedded on an area of the vehicle.

9. A method for collision measurement comprising:

collecting vehicular collision information associated with a vehicle, wherein the vehicular collision information includes a plurality of photonic crystals configured to produce a color change state and at least one location tag configured to store mapping data relating to the location of the photonic crystals formed along the vehicle;

analyzing the color change state and mapping data collected form the vehicular collision information; and

computing a measurement of force caused by collision impact based on the mapping data and color change state of said photonic crystals.

10. The method of claim 9, further comprising:

capturing, via an imaging device coupled to the processing unit, he color change state of associated with at least one photonic crystal;

capturing, via a reading device coupled to the processing unit, mapping data associated with the at least one location tag.

11. The method of claim 10, further comprising:

determining a force value for each of the plurality of photonic crystals based on the color change state of said photonic crystals; and

generating, based on the force values for each of the photonic crystals, a stress map that indicates the distribution of forces over the vehicle.

12. The method of claim 9, wherein the vehicle is a motor vehicle, aircraft, or watercraft device.

13. The method of claim 9, wherein the photonic crystals are only distributed on high probability impact areas.

14. The method of claim 9, wherein the photonic crystals are distributed over the entire body of the vehicle.

15. The method of claim 9, wherein the location tag is an RFID device.

16. The method of claim 9, wherein the location tag is a bar code embedded on an area of the vehicle.

17. A collision measurement system for a vehicle comprising:

a plurality of photonic crystals distributed along the vehicle and configured to produce a color change state;

at least one location tag positioned on the vehicle and configured to provide mapping data relating to a location of the photonic crystals along the vehicle;

an imaging device configured to capture the color change state associated with the plurality of photonic crystals,

a reader device configured to detect the mapping data associated with location tag; and

a processing unit configured to analyze the crystal location data and color state of the plurality of photonic crystals in order to generate a force map that indicates the distribution of forces over the vehicle,

wherein upon receiving external impact, a measurement of force is computed based on the color change state of at least one photonic crystal caused by said impact,

18. The system claim 17, wherein the vehicle is an automobile, motorcycle, aircraft, or watercraft device.

19. The system of claim 17, wherein the photonic crystals are only distributed on high probability impact areas.

20. The system of claim 17, wherein the location tag is an RFID device or a bar code embedded on an area of the vehicle.
