Abstract

A shooting simulation system and method. The system includes a plurality of firearms. Each firearm is associated with a separate soldier having a man-worn computer, a location device for determining a location of the soldier, an optical system for capturing an image where the captured image provides information on a trajectory of a virtual bullet fired from a shooting firearm, and an orientation device for obtaining the orientation of the firearm when shooting the firearm. The optical system is aligned with a sight of the shooting firearm and captures the image when shooting the firearm. The system also includes a shooter/target location resolution module for identifying a valid target and a target image recognition module for determining an impact location where a virtual bullet from the shooting firearm would impact within the captured image and determining if an identified target from the captured image is a hit or a miss.

Claims

1. A shooting simulation system, the system comprising:

a plurality of firearms, each firearm associated with a separate soldier, wherein each soldier has a man-worn computer, a location device for determining a location of the soldier and an optical system for capturing an image, the captured image providing information on a trajectory of a virtual bullet fired from a shooting firearm;

wherein the optical system is aligned relative to a known sight of the shooting firearm, the image recording device capturing the image when shooting the firearm;

an orientation device for obtaining the orientation relative to a known three-dimensional coordinate system of the firearm when shooting the firearm;

a shooter/target location resolution module for identifying a valid target from location information of a targeted soldier;

a target image recognition module for determining an impact location where a virtual bullet from the shooting firearm would impact within the captured image;

wherein the target image recognition module determines if an identified target from the captured image is a hit or a miss.

2. The system according to claim 1 wherein the shooter/target location resolution module utilizes data on an orientation of the shooting firearm obtained from the orientation device, the location of the target and the location of the shooting firearm for identifying a valid target.

3. The system according to claim 1 wherein the location device is a Global Positioning System (GPS) device which generates a known location of the GPS device.

4. The system according to claim 3 wherein the location of the GPS device is a location indicia which is sent to the shooter/target location resolution module.

5. The system according to claim 4 wherein the shooter/target location resolution module determines a range between the shooting firearm and the target.

6. The system according to claim 1 wherein the target image recognition module stores ballistics of the firearm for determining a projected trajectory of the virtual bullet fired from the firearm.

7. The system according to claim 1 further comprising a central computing system communicating with all the man-worn computers.

8. The system according to claim 7 wherein the target image recognition module resides with the central computing system.

9. The system according to claim 1 wherein at least one firearm is affixed to a vehicle.

10. The system according to claim 1 wherein the determination of the trajectory of the virtual bullet and whether the virtual bullet is a hit or miss is performed in a distributed computing network where the calculations are performed by various nodes in the computing network.

11. The system according to claim 1 further comprising a disambiguation module for resolving if a hit or miss of a moving target.

12. The system according to claim 1 further comprising a disambiguation module for resolving if a hit or miss of a concealed target.

13. The system according to claim 12 wherein the disambiguation module applies a Monte Carlo technique for determining a hit or miss of a concealed target.

14. The system according to claim 1 further comprising a disambiguation module utilizing a stored terrain database to assist in determining a hit or miss of a target where terrain is a factor in resolving a hit or miss.

15. The system according to claim 1 wherein the shooter/target location resolution module identifies a valid target by determining if a target is located in a resolution zone, the resolution zone calculated from an orientation of the firearm, the location of the shooting firearm, the location of the targeted soldier and the range between the shooting firearm and the target.

16. A method of simulating firearm use, the method comprising the steps of:

shooting a firearm, wherein the step of shooting includes aiming at a target and triggering the firearm;

obtaining a geographic location of the target to determine the identity of the target;

obtaining the orientation of the shooting firearm relative to a known three-dimensional coordinate system when the firearm is shot;

determining if a target targeted by the shooting firearm is a valid target;

capturing an image during the step of shooting by an optical system associated with the shooting firearm;

providing information on a trajectory of a virtual bullet fired from a shooting firearm by the captured image;

determining an impact location where the virtual bullet from the shooting firearm would impact from the captured image and the trajectory of the virtual bullet; and

determining, from the determined impact location of the virtual bullet and if a target is a valid target, a hit or a miss of the virtual bullet on the target.

17. The method according to claim 16 wherein the step of determining if a target targeted by the shooting firearm is a valid target includes the step of utilizing data on the obtained orientation of the shooting firearm, the location of the target and the location of the shooting firearm for identifying a valid target.

18. The method according to claim 16 wherein the step of determining if a target targeted by the shooting firearm is a valid target includes determining if a target is located in a resolution zone, the resolution zone calculated from an orientation of the firearm, the location of the shooting firearm and the location of the targeted soldier.

19. The method according to claim 16 wherein the step of determining a hit or miss includes utilizing a probability scheme to determine a hit or miss of a concealed soldier.

20. The method according to claim 16 further comprising the step of informing an intended target of a hit of the virtual bullet.
