Abstract

A system for event reconstruction including: a plurality of cameras installed at a location in expectation of an event, each of the cameras being arranged to simultaneously capture video of an area of interest from a unique viewpoint to capture footage of the event occurring at said area of interest; and a processing device; wherein the processing device processes the video captured by the cameras to produce a three-dimensional reconstruction of the event.

Claims

1. A system for event reconstruction including:

a plurality of cameras installed at a location in expectation of an event, each of the cameras being arranged to simultaneously capture photography of an area of interest from a unique viewpoint to capture footage of the event occurring at said area of interest; and

a processing device;

wherein the processing device processes the photography captured by the cameras to produce a three-dimensional reconstruction of the event.

2. A system as claimed in claim 1, wherein the cameras are video cameras and the photography is video photography.

3. A system as claimed in claim 1, wherein the cameras are time-of-flight (TOF) cameras.

4. A system as claimed in claim 1, wherein the processing device stores the three-dimensional reconstruction on a tangible computer readable medium.

5. A system as claimed in claim 2, wherein the processing device allows a user to select an observation point in space different to the viewpoints of the cameras and to view the event from said observation point.

6. A system as claimed in claim 1, wherein the location is a roadway intersection, and the event is a vehicle accident.

7. A system as claimed in claim 1, wherein the event is a criminal event.

8. A system as claimed in claim 7, wherein the location is a bank and the criminal event is a robbery of the bank.

9. A system as claimed in any one claim 6, wherein the processing device allows a user to calculate a velocity of an object in the area of interest at a given time.

10. A system as claimed in any one claim 6, wherein the processing device allows a user to view the event from a perspective of a driver of a vehicle involved in the event.

11. A system as claimed in any one claim 10, wherein the processing device allows a user to determine a position and orientation of the driver'"'"'s head.

12. A system as claimed in claim 1, wherein the processing device provides face recognition of individuals involved in the event.

13. A system as claimed in claim 4, wherein the tangible computer readable medium is local to said system.

14. A system as claimed in claim 1, wherein the processing device transfers the reconstruction of the event wirelessly to a different location.

15. A system as claimed in claim 1, wherein the system uses identification of heat and/or sound associated with an event to initiate capture of photography of the area of interest.

16. A system as claimed in claim 1, wherein storage of the photography captured by the cameras is looped.

17. A system as claimed in claim 1, wherein the processing device combines sound recordal at each of the cameras to contribute to determination of location, direction of movement and/or speed of objects in the area of interest.

18. A method of reconstructing an event including the steps of:

installing a plurality of cameras at a location in expectation of an event;

operating each of the cameras to simultaneously capture photography of an area of interest, each from a unique viewpoint, to capture footage of the event occurring at said area of interest; and

processing photography captured by the cameras to produce a three-dimensional reconstruction of the event.
