Definitions
- the invention relates to the field of fire analysis, and relates to a device and method for the automated analysis of a shot, in particular in the field of training.
- a most commonly used technique is the posteriori observation of the accuracy of the shot. If the shot is made on a target, then this is used to support the verification of the accuracy of the shot. If the shot is aimed at a real target, then the accuracy of the shot is analyzed by the impact of the ammunition (real or via a paintball for example). Another technique is to film the target via an external device allowing the user to check the accuracy of the shot.
- a final approach is to use a laser system coupled to the triggering of the shot and analyzed by an external device, for example by means of markers mounted on the potential targets which transmit to a central system the information whether there is an impact or not. .
- the following references are an illustration of various devices of the prior art:
- Patent EP 0985899 A1 proposes a compact video image recording device which can be mounted on a pistol and used to record video images before and after the pistol is fired.
- the recording device includes a camera comprising a lens and a video image sensor.
- the video recording device is mounted on the gun so that the viewing area of the camera includes the target area of the gun.
- the video image sensor generates an electronic signal representative of a video image striking the respective sensor.
- the output of the image sensor is processed and generally used to produce successive frame data which is stored sequentially in locations of a semiconductor memory organized in circular buffer memory while the video recording device is in a active state.
- additional frames are stored in the buffer for a short period of time and part of the buffer is used to keep a video recording of the shooting before and after the event. Additional frames are successively stored in the unused part of the buffer memory.
- Jekel's US patent 8,022,986 proposes a weapon orientation measurement device which includes a processor configured to receive first location information indicating the locations of a first point and a second point on a weapon, the first and second points being separated by a distance parallel to a pointing axis of the weapon, and for receiving a second location information indicating the locations of the first and second points on the weapon.
- the processor is further configured to receive information indicating a first Earth orientation and determine a second Earth orientation corresponding to the weapon based on the first and second location information and information indicating the first Earth orientation.
- the first location information represents a location relative to a first sensor at a first location and the second location information represents a location relative to a second sensor at a second location, and the first and second sensors are separated by a given distance .
- the patent application US 2012/0178053 A1 from D'Souza et al. relates to a method and a system for a shooting training system which predicts ballistics automatically based on both automatically collected weather and distance information.
- the projectile fire training system also confirms that the manual efforts made by an operator to adjust the turrets would make it possible to reach the target or not after a shot.
- a light or other signal is sent from the weapon to the target to indicate that a shot has been made by the weapon.
- a method known for more than 20 years to tackle this problem consists in equipping potential targets with photosensitive sensors which can send information when these are lit by a LASER.
- the disadvantages of this method are multiple: attenuation of LASER over long distances, inability to fire through blurred obstacles (for example the foliage), the need to equip the target with enough photosensitive sensors, among others.
- An object of the present invention is to propose an autonomous device in energy and in calculation, capable of detecting the start of a shot and of recording via an electro-optical device the place and the date of the impact of the ammunition if this is present or the position simulated by calculating the impact in the case of the use of a blank ball without real impact.
- the device of the invention is available in the form of a kit which can be added simply on the rails of a weapon (for example on a MIL-STD 1913 "picatinny" rail).
- Another object of the present invention is to propose a method for precise analysis of the performance of a shot which makes it possible to generate in real time a report on the accuracy of an impact, and to record it for later consultation. .
- the report can be directly used by the user on a smartphone or a tablet or a virtual reality headset;
- the analysis of a shot is made from the analysis of the movement of the weapon and the posture of the shooter, a ballistic calculation is carried out according to the ammunition used, and there is a precise, automated identification and in real time during the firing, of an impact (which entity, which part of the entity) making it possible to determine a level of damage from the impacts;
- each impact can be analyzed individually;
- the device can be deployed and used anywhere, without special instrumentation;
- the invention will find an advantageous application in the field of simulation, and more particularly in the context of military or police training, for which it is necessary to be able to designate targets in a realistic manner without having recourse to real projectiles. For safety reasons. More generally, the invention can also be implemented for an application dedicated to collective military training, with weapon sizes much larger than light weapons such as that described as an example.
- the device of the invention can be coupled to a system of effectors, thus making it possible to simulate an impact on a target or on an individual instrumented by this same effector, whether it is light or vibration.
- the device of the invention can be used to calculate a trajectory in traversable obstacles (a door, foliage, etc.) and thus remove the limitations (inaccuracies of the laser at long distance, and need to '' a direct view of the target) of laser equipment (STC Laser Combat Fire Simulator).
- the device of the invention can be coupled to a set of sensors placed on the ground, and thus make it possible to make a realistic calculation of a trajectory by taking into account parameters such as wind, pressure, humidity.
- the invention relates to a device for analyzing the impact of a weapon fire on a target, comprising:
- a data acquisition module capable of determining the moment of the departure of a projectile from a weapon and of acquiring video and spatial data relating to a targeted target
- a calculation and storage module capable of analyzing the temporal, video and spatial data acquired
- a data transmission module capable of transmitting the analyzed data.
- the data acquisition module is composed of at least one inertial unit capable of detecting the movement of the breech of the weapon, of a range finder capable of acquiring distance data from the targeted target, at least one camera able to acquire line of sight images.
- the data acquisition module includes two multi-spectral and multi-field cameras.

- FIG. 4 schematically illustrates the phase of data processing according to an embodiment of the method of the invention. Detailed description of the invention
- the device (100) of the invention is shown in Figure 1 as being fitted to a weapon. It mainly consists of:
- the data acquisition module is composed of at least one rangefinder (102) capable of acquiring distance data from a target (10), at least one camera (104, 106) capable of acquiring line of sight images and at least one inertial unit (108) of the 3-axis IMU type capable of detecting the movement of the breech of the weapon at the time of a shot.
- the data acquisition module can be adapted according to the operational context, such as for example for short-range shots, it only requires a single wide field camera, and an IMU.
- the module includes two cameras (104, 106) having different field widths, one with wide field and the other with narrow field.
- the storage and calculation module (1 10) allows the analysis, processing and storage of data.
- it is composed of a computer using resources of the CPU type and of the GPU type (dedicated to calculations performed by neural networks for example), of a training database (208) comprising information relating to targets (people, vehicles, etc.) used for the target detection calculations, and to a data storage capacity (210).
- the calculation module also includes a real-time clock which guarantees precise and drift-free dating of the data collected.
- the data transmission module (1 12) allows communication to a remote device, preferably by a wireless link.
- FIG 2 schematically illustrates the general functions operated by the various components of the device of the invention, and Figures 3 and 4 detail them.
- the analysis method begins with the detection of the triggering of a shot (202).
- the measurement of the moment of departure of a projectile is made by the sensors of the central inertial (108) which detect the movement of the breech of the weapon, ie the simultaneous vibrations on the three axes.
- the detection of the firing start time triggers the recording (204) of the views by the camera (s) (104, 106).
- the target (10) aimed by the gun is recorded digitally by electro-optical means preferably by several cameras, which are both multi-spectral (visible / infrared) and multi-field, and this during the entire time of the movement of the ammunition as well as after impact.
- the device uses a real wide field image and a narrow field image, the images being obtained during the pointing captured by the high resolution multi spectral camera system.
- the wide field / narrow field switching is done automatically on a distance criterion in order to ensure the optimal resolution for the subsequent segmentation (214) of the image.
- two cameras are used, each camera being calibrated independently to allow correction of parallax and ballistics by the calculation module.
- the digital video recording (204) made by all of the sensors is stored and analyzed (206) directly by the computer (110) embedded in the device.
- the computer which analyzes the images from the cameras is able to:
- a synchronization mechanism makes it possible to synchronize the data recorded by all of the components in order to ensure the consistency of the debriefing information.
- the images are stored on the on-board memory (210). If the broadcast mode is activated, these images are transmitted (212) in real time for analysis and segmentation (214) to an external device (216) in order to control the evolution of the score before and after the shot.
- the operation of the system can be divided into two main phases: a first phase of data recording represented by FIG. 3, and a second phase of data processing represented by FIG. 4.
- the data recording phase includes the following sequence of steps:
- the accelerometer detects the movement of the bolt
- the computer interprets the movement of the cylinder head on a window
- image ⁇ (as central);
- the data processing phase illustrated in FIG. 4 comprises two processing sequences carried out in separate processes (400, 410).
- a first sequence (400) is dedicated to resolving the shot. It is very fast (of the order of the flight time of the ammunition) and is only based on the "A" data available immediately after firing.
- a second processing sequence (410) is slower and allows a temporal analysis of the shot. It is based on the data “A” and “B” and on the first sequence, and makes it possible to generate a shooting report.
- the first sequence (400) of data processing "A” allows an analysis of the resolution of a shot, and comprises the following steps:
- 401 Detection of objects present on image C via detection and recognition algorithms. This step makes it possible to identify static targets, humans, elements of interior or urban furniture, weapons, vehicles, etc.
- Ballistic calculation This step makes it possible to determine the position affected in image C by the ammunition, using data from the rangefinder, projection information from the camera (s) and the ballistic profile of the weapon and its ammunition.
- Detection of the target object if an object detected in the previous step is present at the position touched in the image by the ammunition (calculated in step 6), the method proceeds to the next step 404, otherwise the process of the first sequence stops and the ballistics information is communicated to the second sequence.
- the method makes it possible to identify the affected sub-part. For example, for a human, an arm, a trunk, a leg or a head.
- the second sequence (410) of data processing allows a temporal analysis of the shot, and includes the following steps:
- 41 1 Calculation of the optical flux to deduce the deviation of the weapon in pixels, before and after firing.
