DESCRIPTION OF THE INVENTION

[0024] The present invention is a system for simulating live, force-on-force simulated firearms engagements at realistic ranges. The Shooter can be a person with a direct fire small arm, such as a rifle or submachine gun or with an indirect fire or high-trajectory firearm, such as a grenade launcher, or an unmanned ground vehicle or unmanned aerial vehicle. The invention simulates a plurality of firearms. The system is symmetrical and homogenous in that a Shooter can also be a target, and vice versa.

[0025] In FIG. 1 the Shooter 10 and the Target 11 may be reversed. Both the Shooter 10 and Target 11 participants periodically report their estimated location, orientation, and speed to a wireless communication relay 12. These location updates are transmitted 13 to a Remote Server 14, where they are stored in the Entity State Database 15 for later use. The wireless communication relay uses transceivers located in the remote server and in each participant's computer. Though FIGS. 1 and 2 depict a rifle, this invention is not limited to a rifle, but rather supports a plurality of firearms.

[0026] The Shooter 10 aims his firearm at his Target 11 and pulls the trigger which activates a trigger sensor. The Shooter's location, firearm orientation, and sight image are transmitted to the wireless relay. The sight image is a digital representation of the Shooter's view through his firearm's sight when he pulls the trigger. The location and orientation of the Shooter 10 and his sight image are transmitted to the Remote Server 14 and to the Interaction Manager 16. The Interaction Manager queries the target Resolution Module 17, which produce a list of possible targets from the Entity State Database based on the firearm location, orientation, known position sensor error, and known orientation sensor error. This list of possible targets is provided to the Hit Resolution Module 18.

[0027] The Hit Resolution Module 18 runs the multiple, multi-spectral algorithms to find targets in the sight image. Multiple algorithms may be used based on environmental conditions and other factors that influence which algorithms will be the most successful. This step includes processing the sight image to locate targets and determining the relationship between the aim point and the target based on the sight image. For instance, did the Shooter aim high, low, left, or right of center of mass of the target.

[0028] The Hit Resolution Module 18 calls the Target Reconciliation Module 20, which reconciles results from the computer vision computation with information from the Entity State Database. This step identifies which targets from the Target Resolution Module 20 correspond to targets identified by the computer vision algorithm. This step is purely based on the results of employing a plurality of computer vision (CV) algorithms and does not rely on any artificial indicia in the scene. The CV algorithms use a plurality of algorithms to construct a silhouette around the target; however, if the CV algorithms cannot construct a full silhouette, they then construct a bounding box around the targets in the scene.

[0029] The Hit Resolution Module 18 queries the Munitions Fly-out Module 21 for the flight time of the projectile and adjustments to the trajectory of the round. These adjustments can be based on range (e.g., drop of the round over distance), atmospheric effects, weather, wind, interactions with the terrain, and other factors as required to accurately predict the trajectory of the round. The system uses a representation of the terrain in the area of interest to compute whether the simulated projectile struck the target.

[0030] The Hit Resolution Module 18 computes whether the trajectory of the round intersects the target determined by the Target Reconciliation Module 17 based on the adjusted trajectory, time of flight, and relative velocity of the target. Relative velocity accounts for movement of the target, the Shooter, and the Shooter's firearm. If the round strikes the projected target location at time of impact, the Hit Resolution Module 18 calls the Damage Effects Module 22. This module computes the damage to the target based on the firearms characteristics, the munitions characteristics, and location of the calculated impact point in the target's calculated silhouette. Damage effects indicate the extent of damage to the target, such as whether the target was killed, sustained a minor wound or major wound, the location of the wound, and the like.

[0031] A near miss is reported through the wireless relay 12 and retransmitted to the Target 11 and the Shooter 10, respectively, who are informed of the near-miss results via audio and visual effects similar to the existing MILES system. A hit result is reported through the wireless relay 12 and re-transmitted to the Target 11 and the Shooter 10, respectively. The Shooter is notified of a hit, and the Target is notified that he was hit, with what firearm or round he was hit, and the severity of the damage.

[0032] FIG. 2 displays the configuration of the firearm sub-system. The Position Location Sensor 23, which incorporates a GPS system, provides periodic updates of the participant's location, orientation, and speed to the Participant-Worn Computing Device 24. The Participant-Worn Computing Device transmits these updates to the wireless relay 12.

[0033] When the participant pulls the trigger on his training rifle, the Trigger Pull Sensor 25 sends a message to the Participant-Worn Computing Device 24. The Participant-Worn Computing Device 24 captures the trigger-pull events. The Firearm Orientation Sensor 26 returns the firearm orientation to the Participant-Worn Computing Device 24. Similarly, the Image Capture Device 27 provides the sight image as seen by the Shooter 10 to the Participant-Worn Computing Device. The Image Capture Device 27 may provide: [0034] 1. A mix of visible spectrum, non-visible spectrum, and multi-spectral images. [0035] 2. A video image or a series of still images. [0036] 3. Images from a single viewpoint or multiple viewpoints. [0037] 4. Images from narrow and wide-angle viewpoints.

[0038] The Participant-Worn Computing Device 24 sends the location and orientation of the firearm as well as the sight images via the Wireless Relay 12 to the Remote Server 14.

[0039] The target is not augmented with indicia or beacons. Other than the participant-worn subsystem, the target includes only his operational equipment.

[0040] In FIG. 1 the Shooter is indicated as 10, and the Target is 11; however, in this approach the roles may be reversed. As shown in FIG. 3A, Step 100, both the Shooter 10 and Target 11 periodically report their estimated location, orientation, and speed to a wireless communication relay 12.

[0041] The Orientation Sensor 26 provides three-dimensional orientation with respect to the geomagnetic frame of reference. This three-dimensional representation can be in the form of a quaternion; yaw, pitch, and roll; or other frame of reference, as appropriate. The Orientation Sensor 26 is calibrated to the fixed coordinate system when the system is turned on, and it can be periodically recalibrated during a simulation event as necessary. The orientation sensor may employ a plurality of methods to determine three-dimensional orientation. There is no minimum accuracy requirement for the Orientation Sensor 26; although, a more accurate orientation sensor reduces the burden on the Target Reconciliation Module 17.

[0042] The Location Sensor 23 provides the Shooter's location with respect to a fixed reference frame. In the current embodiment, this is provided as latitude and longitude, but other coordinate representation methods may be employed. The participant's speeds may be measured directly by the position sensor or may be inferred through the collection of several position reports over time.

[0043] The location, orientation, and velocity updates are transmitted 13 to a Remote Server 14, where they are stored in the Entity State Database 15 for later use, as shown in FIG. 3A, Step 101. These updates occur at sufficient rapidity that the Remote Server can accurately estimate each Participant's velocity.

[0044] As depicted in FIG. 3A, Steps 102 and 103, the Shooter 10 aims his firearm at his Target 11 and pulls the trigger. The event of the trigger being pulled can be sensed electronically to complete a circuit for sending a message to the Participant-Worn Computer 24, or the trigger sensor 25 can be activated by a combination of acoustic, flash, and shock signatures. As depicted in FIG. 3A, Step 104, when the participant pulls the trigger on his firearm, the Trigger Pull Sensor 25 sends a message to the Participant-Worn Computing Device 24. The Participant-Worn Computing Device 24 sends the trigger-pull events to the Remote computer Service 14. The Firearm Orientation Sensor 26 returns the firearm orientation to the Participant-Worn Computing Device 24. Similarly, the Image Capture Device 27 provides the sight image as seen by the Shooter to the Participant-Worn Computing Device 24.

[0045] As shown in FIG. 2, the participant-worn subsystem includes an Orientation Sensor 26 on the firearm, an Image Capture Device 27 on the firearm, and a Position Location Sensor 23. The Orientation Sensor 26 and Image Capture Device 27 may be collocated or mounted separately. The Trigger Pull Sensor 25, Position Location Sensor 23, Orientation Sensor 24, and Image Capture Device 27 may be connected to the Participant-Worn Computing Device 24 though a cable or wireless radio link.

[0046] The sight image is a digital representation of the Shooter's view through his firearm's sight when he pulls the trigger. The image capture device 27 is aligned with the barrel and sights of the simulated firearm so that the image captured from the device is an accurate representation of the Shooter's sight picture when the trigger was pulled. In the first embodiment of the invention, the image capture device 27 is the same scope through which the Shooter is aiming the firearm, but the image capture device may be separate form the weapon sights. The image capture device 27 may provide:

[0047] A mix of visible spectrum, non-visible spectrum, and multi-spectral images;

[0048] A video image or a series of still images;

[0049] Images from a single viewpoint or multiple viewpoints; and

[0050] Images from narrow and wide-angle viewpoints.

[0051] The Position Location Sensor 23 provides periodic updates of the participant's location, orientation, and speed to the Participant-Worn Computing Device 24. The Participant-Worn Computing Device transmits these updates to the wireless relay 12.

[0052] FIG. 3A, Step 105, the Participant-Worn Computing Device 24 transmits the Shooter's location, firearm orientation, and sight image to the wireless relay 12. This Wireless Relay may be any communications means with sufficient bandwidth to process the information, depending on the number of simultaneous participants. The Wireless Relay may be incorporated into the Participant-Worn Computing Device 24 or it may be a separate radio linked to the Participant-Worn Computer 24 through a cable or other wireless link.

[0053] The location and orientation of the Shooter 10 and his sight image are transmitted from the Wireless relay 12 to the Remote Server 14 and the Interaction Manager 16. Any communication means with sufficient bandwidth may be used in this step of the process. The Participant-Worn Computing Device 24 may perform preprocessing of the captured sight picture to reduce bandwidth requirements. Pre-processing includes, but is not limited to, cropping the image, reducing the resolution of the image, compressing the image, and/or adjusting the tint, hue, saturation, or other attributes of the image.

[0054] In FIG. 3A, Step 106, the Interaction Manager queries the Target Resolution Module 17 for a list of possible targets. In FIG. 3A, Step 107, The Target Resolution Module 17 produces a list of possible targets from the Entity State Database 15 based on the firearm location, orientation, known position sensor error, and known orientation sensor error. Target resolution is the first step in the hit detection pipeline. The Target Resolution algorithm uses Shooter position, target positions previously reported and stored in the Entity State Database 15, and the field of view of the Image Capture Device to determine which targets, if any, may be present in the sight picture. The determination is based on whether the target is alive or dead and whether the target's reported position lies within a cone built using the known position and orientation errors of the sensors. If no living target candidates are within field of view of the Image Capture Device 27, the Interaction Manager 16 records the shot as a miss due to the lack of targets and no further processing is done.

[0055] The Target Resolution Module 17 provides this list of possible targets to the Hit Resolution Module 18. In FIG. 3A, Step 108, the Hit Resolution Module 18 employs a plurality of computer vision (CV) algorithms to find targets in the captured sight image. Multiple algorithms may be used based on environmental conditions and other factors that influence which algorithms will be the most successful.

[0056] In FIG. 3B, Step 109, the Hit Resolution Module 18 processes the sight image to locate targets and determining the relationship between the aim point and the target based on the sight image. For instance, did the Shooter aim high, low, left, or right of center of mass of the target. The Hit Resolution Module 18 identifies target silhouettes in the scene. Where targets are partially occluded, the Hit Resolution Module 18 “fills in” the occluded portion of the target using an appropriate image processing technique, taking into account the target's posture and speed. If the CV algorithms cannot construct a full silhouette, it then instead constructs a bounding box around the targets in the scene.

[0057] In FIG. 3B, Step 110, the Target Reconciliation Module 20 reconciles results from the computer vision computation with information from the Entity State Database 15. The Hit Resolution Module 18 is responsible for identifying human targets within the sight picture and matching them to potential targets from the list generated by the Target Resolution Module 20. This step identifies which targets from the Target Resolution Module 20 correspond to targets identified by the computer vision algorithm. This step is purely based on the results of employing a plurality of computer vision (CV) algorithms as well as heuristics and does not rely on any artificial indicia in the scene.

[0058] Having determined the intended target, in FIG. 3B, Step 111, the Hit Resolution Module 18 queries the Munitions Fly-out Module 21 for the flight time of the projectile and adjustments to the trajectory of the round. Flight time of the projectile is based on the distance between the Target and the Shooter. This step uses the reported locations of the Target and Shooter that are stored in the Entity State Database 15. Adjustments to the trajectory of the round can be based on range (e.g., drop of the round over distance), atmospheric effects, weather, wind, interactions with the terrain, and other factors as required to accurately predict the trajectory of the round. The Hit Resolution Module 18 employs the Munitions Fly-Out Module 21 to compute whether the trajectory of the round intersects the target determined by the Target Reconciliation Module 20 based on the adjusted trajectory, time of flight, and velocity of the target. While at very short ranges, small arms fire may be simulated as instantaneous, for distance targets and slower weapons, such as anti-tank guided missiles (ATGMs), predicting where the round impacts targets based on adjusted trajectory, distance between the Shooter and Target, time of flight of the munition, and atmospheric conditions is critical to realistic simulation of these engagements. In addition, the Hit Resolution Module 18 accounts for the minimum arming distance of some munitions, such as grenades, mortars, and anti-tank rockets that must travel a certain distance before the fuse arms and the round may detonate.

[0059] In FIG. 3B, Step 112 when a Shooter fires at a moving target, the relative velocity of the target stored in the Entity State Database 15 is used to predict the location of the target at the time of flight of the simulated projectile. Relative velocity accounts for movement of the target, the Shooter, and the Shooter's firearm. In FIG. 3B, Step 113, if the trajectory of the round intersects with the projected position of the target silhouette of the target at the time of impact of the simulated projectile, a possible hit is scored.

[0060] In FIG. 3B, Step 114, the system uses a representation of the terrain in the area of interest to compute whether the simulated projectile struck the target. This terrain representation includes the undulations of the ground, vegetation, trees, and other features necessary for this computation. If the trajectory of the round passes through terrain, the Hit Resolution Module 18 determines whether the bullet could pass through the terrain. For instance, a bullet may not pass through sufficient amounts of dirt or sufficiently thick trees; however, a bullet may pass through a hay bale or bush. The Target Resolution Module 20 computed the full silhouette for partially occluded targets. As the Munitions Fly-Out Module 21 is computing the trajectory of the simulated projectile, if the projectile encounters an obstacle through which the projectile may not pass, the Interaction Module 16 records a miss. On the other hand, the Munitions Fly-Out Module 21 computes the trajectory of the simulated projectile, if the projectile encounters an obstacle through which the projectile can pass, the Munitions Fly-Out Module 21 continues to compute the trajectory of the projectile. In this way, the invention can compute a hit on a portion of a target that is partially occluded by terrain that cannot stop a bullet.

[0061] The Munitions Fly-Out Module 21 accounts for weapon systems that detonate based on range to the target, distance from the firearm, or other factors, by determining when the detonation occurs. As an example, but not a limitation of the invention, if a Shooter fires simulated munitions from his firearm that explode at a pre-sent distance, the Munitions Fly-Out Module 21 computes the trajectory of the munitions to their points of detonation. The locations where the munitions detonated are then passed to the Damage Effects Module 22 to compute damage to any nearby participants.

[0062] In FIG. 3B, Step 115, if the round struck the target, the Hit Resolution Module 18 calls the Damage Effects Module 22. The Damage Effects Module 22 computes the location where the simulated projectile struck the target. Using this location computation, the Damage Effects Module 22 computes the damage to the target based on the firearm's characteristics, munitions characteristics, and location of the impact point in the projected target silhouette at the time of impact. Example results include whether the target was killed, sustained a minor wound or major wound, and the type of wound.

[0063] In FIG. 3B, Step 116, a hit result is reported through the wireless relay 12 and retransmitted to the target 11 and the Shooter 10, respectively. The Shooter 10 is notified of a hit, and the Target 11 is notified that he was hit, with what firearm or round he was hit, and the severity of the damage. This information is available on his Participant-Worn computing device 24. This information may stimulate additional training. For instance, a medic might approach the target and read information about the wound on a display so that he can employ the most appropriate first aid techniques.

[0064] In FIG. 3B, Steps 117 and 118, a near miss is reported through the wireless relay 12 and retransmitted to the Target 11 and the Shooter 10, respectively, who are informed of the near-miss results on their Participant-Worn Computing Devices 24. For training purposes this information may be recorded for later analysis and use or may be presented in situ to the participants. A miss is not generally reported unless there would be a signature of the shot that the participant could see, such as the blast from a grenade. The reporting of hits and misses can be configured based on different training situations. For instance in one training mode, the system sends feedback to the Shooter 10 after each shot so that the Shooter 10 may learn from each shot and improve his marksmanship. In another training mode, such as simulating a firefight, this constant feedback from the system to the Shooter 10 may be both distracting and inappropriate. In such a situation, the messages to the Shooter 10 may be suppressed during the event and reported afterward.

[0065] The system records information from the Remote Server 14 to assist in reviewing the training event. Information such as, but not limited to, participant's locations over time, sight pictures when triggers were pulled, sight pictures after the CV algorithms have processed them, results from the Target Reconciliation Module 20, and status of participant-worn devices may be displayed to an event controller during and after the training event.

[0066] This invention is equally applicable to high-trajectory or non-line of sight shooting. In the case of high-trajectory fire, the image from the Image Capture Device 27 is not necessary. The modified process for non-line of sight and high-trajectory shooting is depicted in FIG. 4. Steps 200-203 are exactly the same as Steps 100-103 in FIG. 3A. For high-trajectory fire, a camera bore sighted with the barrel of the weapon is unlikely to see the target, so no sight picture is collected and transmitted. Instead, as shown in FIG. 4, Step 204, the location of the Shooter 10 and the orientation of his weapon is transmitted to the remote server 14. The Munitions Fly-Out Module 21 computes the trajectory of the simulated projectile in Step 205. This computation accounts for the characteristics of the munitions, environmental effects, velocity of the Shooter and his weapon, and the terrain database to determine the point of impact or detonation of the munitions. This computation does not benefit from the sight picture as for direct-fire engagements, so its accuracy is solely dependent on the accuracy of the Position Location Sensor 23 and Weapon Orientation Sensor 26.

[0067] In Step 206, the Target Resolution Module 17 queries the Entity State Database 15 to determine whether any participants, friendly or enemy, are within the burst radius of the simulated munitions. In Step 207, the Munitions Fly-Out Module 21 predicts the locations of those participants at the time of impact or detonation of the simulated munitions. In Step 208, for each participant within the burst radius of the munitions, the Damage Effects Module 22 determines if the participant is hit, where the target was hit, and the severity of the damage, just as described in Step 115, FIG. 3B.

[0068] In Step 209, if a participant received a hit from a high-trajectory shot, in Step 212, the target is notified of the results, including location(s) and severity of wounds. The Shooter 10 may be notified that he has hit his target as well. In an augmented reality situation, this notification might come in the form of a depiction of an explosion near the target(s). If the high-trajectory shot is a miss or near miss, in Step 210, this is reported to the target. The Shooter 10 may also be notified in Step 211. The reporting of hits and misses can be configured based on different training situations. For instance in one training mode, the system sends feedback to the Shooter 10 after each shot so that the Shooter may learn from each shot and improve his marksmanship. In another training mode, such as simulating a firefight, this constant feedback from the system to the Shooter 10 may be both distracting and inappropriate. In such a situation, the messages to the Shooter 10 may be suppressed during the event and reported afterward.

[0069] It should be clear at this time that a shooting simulation system for personnel, unmanned systems, and vehicles has been provided that enables non-line of sight engagements and permits firing through obscurants and terrain features like bushes and tall grass. However the present invention is not to be considered limited to the forms shown which are to be considered illustrative rather than restrictive.
