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 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; and

at least one location tag bonded to the area having the plurality of photonic crystals and positioned on the vehicle, wherein the at least one location tag is configured to store and provide mapping data relating to a location of the plurality of photonic crystals on the vehicle,

wherein upon receiving an external impact, a measurement of force is computed based on the color change state of at least one photonic crystal caused by the external impact and the mapping data of the plurality of photonic crystals that provides a reference positioning of the plurality of photonic crystals on the vehicle is used to construct a post-crash force map associated with a deformation of a body of the vehicle caused by the external impact.

2. The system of claim 1, further comprising:

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

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

3. The system of claim 2, further comprising:

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

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

5. The system of claim 1, wherein the plurality of photonic crystals is only distributed on specific areas.

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

7. The system of claim 1, wherein the at least one location tag is a radio frequency identification (RFID) element.

8. A method for collision measurement comprising:

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

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

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

constructing a post-crash force map associated with a deformation of a body of the vehicle caused by the collision impact based on the mapping data of the plurality of photonic crystals that provides a reference positioning of the plurality of photonic crystals on the vehicle.

9. The method of claim 8, further comprising:

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

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

10. The method of claim 9, further comprising:

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

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

11. The method of claim 8, wherein the vehicle is a motor vehicle, an aircraft, or a watercraft device.

12. The method of claim 8, wherein the plurality of photonic crystals is only distributed on specific areas.

13. The method of claim 8, wherein the plurality of photonic crystals is distributed over an entire body of the vehicle.

14. The method of claim 8, wherein the at least one location tag is a radio frequency identification (RFID) device.

15. A 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 bonded to each area having the plurality of photonic crystals and positioned on the vehicle, wherein the at least one location tag is configured to provide mapping data relating to a location of the plurality of 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 the at least one location tag; and

a processing unit configured to analyze the location of the plurality of photonic crystals and the color change state of the plurality of photonic crystals in order to generate a post-crash force map that indicates a distribution of forces over the vehicle based on the mapping data of the plurality of photonic crystals that provides a reference positioning of the plurality of photonic crystals on the vehicle,

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

16. The system of claim 15, wherein the vehicle is an automobile, a motorcycle, an aircraft, or a watercraft device.

17. The system of claim 15, wherein the plurality of photonic crystals is only distributed on specific areas.

18. The system of claim 15, wherein the at least one location tag is a radio frequency identification (RFID) device.
