Definitions
- the invention relates to shooting training equipment suitable for indoor exercises.
- the device according to the invention is suitable for training one or more shooters. It comprises at least one weapon equipped with a device for firing by the shooter and with an infrared beam emitter, the emission of which is controlled by firing.
- the transmitter of the laser transmitter type, can advantageously be mounted on any real weapon, whether for example semi-automatic or automatic individual weapons, individual anti-tank weapons, collective anti-tank weapons (such such as rockets, recoilless cannons, missiles), or weapons with ballistic projectiles under a turret.
- this device also includes on the weapon a detector element adapted to detect the infrared target.
- the output of each detector element is connected to an instructor station which includes a microprocessor computer which is programmed to tell an infantryman and an instructor whether the shooter has actually fired at the visible target.
- An infrared television camera detects the spots sent by the laser beam when the shot is fired and this camera is connected to a screen for viewing the target as well as the position of the spot of the laser beam.
- the device according to this document has the disadvantage of requiring the use of two projectors, one with infrared and the other with visible light, involving complex equipment, and the association on the aiming weapon of an element. detector comprising a large electronic assembly.
- Another target device constituted by a projected image is described by French patent FR-A-2 456 933.
- This device comprises a target projection screen interposed between a projector and a gunner, equipped for example with a cannon or a 'a missile launcher.
- the target projection screen is a translucent projection screen.
- This device also includes a line of sight detector comprising optical means formed by pivoting mirrors and fixed mirrors.
- An impact point projector is also provided for projecting a visible light beam coaxially via the same optical means with pivoting mirrors.
- the apparatus of this document has the drawback of requiring the screen to be placed between the projection means and the shooter, which constitutes a significant use of space, as well as requiring complex optical and electronic means in order to be able to follow the aim of the shooter.
- the present invention therefore aims to produce a training device for indoor shooting having simple apparatus which can be easily installed and making it possible to obtain a visualization of the point of impact on a video screen presenting the shooting range visible to the shooter.
- This simplification of apparatus is achieved by the use of a retractable visible light filter placed in front of a camera scanning the screen presenting the field.
- This retractable filter has two positions: a first position in which the camera detects the point of impact on the screen of the laser beam and a second position, passive, where the filter is removed and where the camera reproduces the landscape and the target seen by the shooter.
- Electronic means such as a microprocessor make it possible to transcribe the point of impact on a video screen.
- the device according to the invention comprises a certain number of elements which are known and used conventionally in similar applications.
- it includes image scrolling projection means, of the camera type, for presenting to the shooter's view the visible image of a field on which there is at least one target to be reached, whether it is fixed, or evolving on a landscape.
- one of the advantages of the invention is that it is not necessary to have a recording of images of a particular type.
- a simple cinematographic recording on current film is perfectly suitable, as is a recording.
- the device according to the invention comprises a certain number of elements which are known and used conventionally in similar applications.
- it includes image scrolling projection means, of the camera type, for presenting to the shooter's view the visible image of a field on which there is at least one target to be reached, whether it is fixed, or evolving on a landscape.
- one of the advantages of the invention is that it is not necessary to have a recording of images of a particular type.
- a simple cinematographic recording on current film is perfectly suitable, as is a video recording.
- means are provided for imposing a predetermined delay between firing and stopping the scrolling of images, so as to simulate by this delay the time that would take the projectile or the missile launched, in reality, to cover the distance between the weapon and the target.
- This delay can itself be determined by a computer, on the basis of data which can either be entered for example by the instructor or available in coded form on one of the magnetic tracks of the projected film normally intended for sound.
- the device of the invention nevertheless constitutes a tool of great precision, by the fact that it is the same equipment which ensures the detection, on the same screen, of the projected image of the landscape and of the target. and the point of impact of the shot.
- the corresponding information is found in the same video signal for the reconstruction of the superimposed images and the errors of drift, position, linearity have no effect on the assessment of the results of the shooting. Initial system settings are virtually nonexistent. All these advantages are obtained without the need to use a film of special design for projection.
- the drive device comprises means for correcting, in a predetermined manner, either the direction of the infrared beam relative to the aim of the weapon, during firing, or preferably, the position of the beam trace detected on the immobilized image when it is embedded in the video image.
- the trace of the infrared beam which is detected and whose figuration is embedded in the immobilized image can be either punctual (and represented by a cross for example), or linear and constituted by several points detected at different moments before the immobilization of the image, to materialize the positions of a missile.
- an appropriate calculator makes it possible to take into account in the firing result various information, such as the particularities of the weapon used and the ballistic characteristics of the corresponding simulated ammunition, aerological disturbances, information relating to the targets (distance, position, displacement, congestion, or other).
- Information of this kind can come from the projection device, which contains it for example on one of the sound tracks of the film.
- FIG. 1 there is shown an image viewing screen (1), a projector (2), of any conventional type as used in cinema for the projection of films impressed with evolving images, and connected to a sound baffle (18), a video camera (3), and a rifle (4), the barrel of which carries a laser transmitter (5), capable of emitting on command a brush of infrared light by pulses.
- All these elements are oriented towards the same screen (1).
- the focus of the projector (2) is adjusted to produce a clear image on the screen (1)
- the camera (3) takes the image broadcast by the screen and scans it into a video image
- the rifle is aimed manually by the shooter to aim at a target appearing on the screen.
- This target is integrated into the projected cinematographic film, which represents a landscape in which it evolves.
- the same landscape may as well contain several targets from which the shooter will choose.
- the target (s) could also come from a different projector to be projected on the same screen superimposed with, for example, a fixed landscape from a slide projector.
- the cinematographic projector could be replaced by a video projector, controlled by a video signal containing all the information relating to the landscape and to the target in order to reconstruct the corresponding images on the screen ( 1).
- both the landscape image and the target image can come from images of real objects previously recorded, or can be produced by electronic synthesis in the video signal.
- the cinema projector can be replaced by a slide projector for the landscape background, the targets and the impact figuration being generated synthetically by a video projector and superimposed on the landscape on the screen 1.
- the same elements are all functionally connected to an electronic control unit, constituted by a computer (8) with microprocessors, associated with a control console (15) placed in the hands of the instructor who guides the exercises.
- a headset (9) also placed under the control of the computer (8), can be used to make the shooter hear a sound evoking a real shot when he operates the trigger of the rifle (14) to trigger a fictitious shot .
- the computer (8) is essentially used for processing video signals. Thus, it continuously analyzes the signal from the video camera (3), while it determines the signal which controls the projection of the images on a television screen (11).
- the latter is arranged to be observable by the instructor, and preferably also by the shooter (s), so as to allow them to appreciate the results of the shooting. If there is more than one shooter, several video monitors can be connected in parallel.
- the device which is described here in a relatively simple embodiment, where it is operated by a single shooter actuating a single rifle can be modified in designs obvious to those skilled in the art, for s '' adapt to several shooters working with the same instructor. If necessary, provision may be made in this case to distinguish the results of the different shots fired by the different shooters, either by the fact that they are aimed at different targets, or by appearing on the television screen (11) impact from different shots by different symbolizations, or by assigning to the laser emitters of the different rifles different codings of the laser pulse trains which are recognized by the computer during the firing.
- the rifles can be replaced by any other kind of weapon suitable for indoor training.
- This camera (3) is equipped with a retractable filter (12). It is a visible light absorbing filter, which is chosen to be selectively traversed by radiation of the same wavelength range as the ray produced by the laser emitter. As an example, it can be assumed that these are 0.9 micron infrared rays.
- the filter (12) is interposed in front of the camera lens, which is therefore sensitive exclusively to this infrared radiation.
- the filter is mounted on the axis of a rotary electromagnet (13) placed under the control of the computer, which allows the filter to be retracted by tilting it away from the path of the light rays between the projection screen and camera.
- This tilting of the filter is controlled by the computer (8), at the same time as the latter also controls the triggering of the laser emission at the start of the shot, with however between the two sufficient time for the laser beam reflected by the screen is received by the camera and detected in the video signal, before the filter switches over.
- the detection by the camera (3) and the analysis of the video signal by the computer make it possible, in a first step, to detect the position of the trace of the laser beam on the projection screen and to determine the coordinates, before analyzing, in a second step, all of the information relating to the image projected by the projector (2), in at least the entire field of visible light radiation.
- This projection has nevertheless place, on the screen (1), during the entire time when the shooter prepares for aiming, before the start of the shot.
- a filter (16) for absorbing infrared radiation which eliminates the latter, at least in the range of wavelengths that passes the filter (12) placed in front of the camera.
- the computer (8) also controls the stopping of the film running in the projector, so that in the projected images, both the landscape and the target then remain fixed in the position which was the them when the shot is fired. It is this immobilized image which is translated into the video signal and retransmitted by the computer to the monitor, for viewing on the television screen (11).
- the calculator also displays there, by overlaying in the video signal, a symbolic figuration of the point of impact, a cross for example, in the position previously determined by the calculator for the trace of the laser brush. On the television screen, the instructor and the shooter can therefore observe the results of the shooting and discuss them at leisure, on the image of the landscape and the target frozen at the time of the shot.
- the device of the invention is suitable without restriction for training in the use of weapons such as rifles, producing direct ballistic projectiles, over distances which can be neglected. incidence.
- weapons such as rifles, producing direct ballistic projectiles, over distances which can be neglected. incidence.
- various improvements can be made to this device to adapt it to other uses.
- the simulation of the distance effect can be ensured by programming the calculator so that it imposes at the end of the projection of the landscape and target images, a delay from the start of the shot corresponding to the travel time of the projectile over the distance evaluated beforehand, either by direct indication from the instructor, or by reading coded information from the projection film or other image support.
- the ballistics simulation it can be carried out by correcting the value of the arrow, calculated for this distance, the position of the point of impact between its detection by the camera during the emission of the laser brush and its figuration symbolic in the display on the video screen.
- successive pulse trains of the laser emission it may be advantageous to use successive pulse trains of the laser emission.
- the weapon is supposed to fire a missile that the shooter can guide relative to the line of sight
- the recording by the camera of the traces produced on the projection screen by these successive laser pulses allows continuous memorization of the line corresponding to the aiming reticle, and one can make this complete line appear, by overlay in the video signal, on the landscape reproduced with the target in its position at the time of impact.
- Successive laser pulses can also be used to simulate a burst fire. It is possible, for example, to produce laser pulse trains at the rate of a submachine gun fire, and to insure the video signal by showing the various points of impact. As the image of the landscape is frozen, whether its immobilized position is that of the beginning or that of the end of the shooting, this implies that one neglects the evolution of the target or targets during the time of the burst.
- the point of impact which is mentioned throughout the description corresponds to the point of passage of the projectile in the vertical plane located at the level of the target and perpendicular to the axis of aiming shooter-target.
- the projection system is provided with an optical filter (17) attenuating light, which makes it possible to simulate a night atmosphere, on command of the instructor. It is then interposed in front of the objective during the aiming by the shooter, but it is retracted after the shooting, so that the camera provides a fully lit image for the observation of the result of the shooting.
- a control accessible on the desk allows the instructor to control its positioning by means of a rotary electromagnet (18).
- the device can be equipped with various mechanisms at the level of the weapon to simulate particular effects.
- a recoil effect at the time of firing can be brought about by a movement of the weapon triggered upon firing.
- a movement by shaking can be obtained in particular by a vibrating mass mounted on the weapon and controlled by an electromagnet or by an injection of air.

Abstract
Description
L'invention concerne les matériels d'entraînement au tir convenant pour les exercices effectués en salle.The invention relates to shooting training equipment suitable for indoor exercises.
Le dispositif selon l'invention convient pour l'entraînement d'un ou plusieurs tireurs. Il comporte au moins une arme équipée d'un dispositif de mise à feu par le tireur et d'un émetteur de faisceau infrarouge, dont l'émission est commandée par la mise à feu. L'émetteur, du type des émetteurs laser, peut avantageusement être monte sur toute arme réelle, qu'il s'agisse par exemple d'armes individuelles semi-automatiques ou automatiques, d'armes individuelles antichars, d'armes collectives antichars (tels que roquettes, canons sans recul, missiles), ou d'armes à projectiles balistiques sous tourelle.The device according to the invention is suitable for training one or more shooters. It comprises at least one weapon equipped with a device for firing by the shooter and with an infrared beam emitter, the emission of which is controlled by firing. The transmitter, of the laser transmitter type, can advantageously be mounted on any real weapon, whether for example semi-automatic or automatic individual weapons, individual anti-tank weapons, collective anti-tank weapons (such such as rockets, recoilless cannons, missiles), or weapons with ballistic projectiles under a turret.
Dans ce cadre, on s'intéresse plus particulièrement à des matériels de base peu onéreux, impliquant des coûts d'exploitation minimes, ces matériels étant suffisants néanmoins pour assurer un entraînement préliminaire valable des tireurs, avant des exercices de tir à l'extérieur. Une autre particularité de l'entraînement en salle est d'être souvent utilisé pour l'entraînement pour la manipulation d'armes d'infanterie, auquel cas les faibles dimensions des armes ne permettent pas de monter dessus des dispositifs de simulation de tir encombrants.In this context, we are more particularly interested in inexpensive basic equipment, implying minimal operating costs, this equipment being sufficient nevertheless to ensure a valid preliminary training of the shooters, before shooting exercises outside. Another peculiarity of indoor training is that it is often used for training in the handling of infantry weapons, in which case the small dimensions of the weapons do not allow mounting on bulky fire simulation devices.
Les dispositifs d'entraînement au tir en salle pour la manipulation d'armes d'infanterie connues dans l'art antérieur, sont notamment décrits par le brevet américain US-A-4 336 018 qui concerne un dispositif d'entraînement d'infanterie électro-optique. Ce dispositif comporte deux moyens de projection, l'un présentant à la vision du tireur des images d'un champ avec au moins une cible à atteindre, et un second, disposé à côté du premier, ayant pour fonction de projeter simultanément sur l'écran une cible infrarouge.The indoor shooting training devices for handling infantry weapons known in the prior art, are described in particular by American patent US-A-4 336 018 which relates to an electro infantry training device -optical. This device comprises two projection means, one presenting to the shooter's vision images of a field with at least one target to be reached, and a second, placed next to the first, having the function of simultaneously projecting onto the screen an infrared target.
D'autre part ce dispositif comprend également sur l'arme un élément détecteur adapté pour détecter la cible infrarouge. La sortie de chaque élément détecteur est connectée à une station pour instructeur qui comprend un ordinateur à microprocesseur qui est programmé de manière à indiquer à un homme d'infanterie et à un instructeur si le tireur a effectivement tiré sur la cible visible. Une caméra de télévision à infra- rouge détecte les spots envoyés par le faisceau laser lorsque le tir est déclenché et cette caméra est reliée à un écran de visualisation de la cible ainsi que de la position du spot du faisceau laser. Le dispositif selon ce document a l'inconvénient de nécessiter l'utilisation de deux projecteurs, l'un à infrarouge et l'autre à lumière visible, impliquant des appareillages complexes, et l'association sur l'arme de visée d'un élément détecteur comportant un ensemble électronique important.On the other hand this device also includes on the weapon a detector element adapted to detect the infrared target. The output of each detector element is connected to an instructor station which includes a microprocessor computer which is programmed to tell an infantryman and an instructor whether the shooter has actually fired at the visible target. An infrared television camera detects the spots sent by the laser beam when the shot is fired and this camera is connected to a screen for viewing the target as well as the position of the spot of the laser beam. The device according to this document has the disadvantage of requiring the use of two projectors, one with infrared and the other with visible light, involving complex equipment, and the association on the aiming weapon of an element. detector comprising a large electronic assembly.
Un autre appareil à cible constituée par une image projetée est décrit par le brevet français FR-A-2 456 933. Cet appareil comprend un écran de projection de cible interposé entre un projecteur et un tireur, muni par exemple d'un canon ou d'un lance-missile. L'écran de projection de cible est un écran de projection translucide. Cet appareil comprend également un détecteur de ligne de mire comprenant des moyens optiques formés par des miroirs pivotants et des miroirs fixes. Un projecteur de point d'impact est également prévu pour projeter un faisceau de lumière visible coaxialement par l'intermédiaire des mêmes moyens optiques à miroirs pivotants. L'appareil de ce document présente l'inconvénient d'obliger à placer l'écran entre le moyen de projection et le tireur, ce qui constitue une utilisation de place importante, ainsi que de demander des moyens optiques et électroniques complexes afin de pouvoir suivre la visée du tireur.Another target device constituted by a projected image is described by French patent FR-A-2 456 933. This device comprises a target projection screen interposed between a projector and a gunner, equipped for example with a cannon or a 'a missile launcher. The target projection screen is a translucent projection screen. This device also includes a line of sight detector comprising optical means formed by pivoting mirrors and fixed mirrors. An impact point projector is also provided for projecting a visible light beam coaxially via the same optical means with pivoting mirrors. The apparatus of this document has the drawback of requiring the screen to be placed between the projection means and the shooter, which constitutes a significant use of space, as well as requiring complex optical and electronic means in order to be able to follow the aim of the shooter.
La présente invention vise donc à réaliser un dispositif d'entraînement au tir en salle présentant un appareillage simple pouvant être facilement installé et permettant d'obtenir une visualisation du point d'impact sur un écran vidéo présentant le champ de tir visible par le tireur. Cette simplification d'appareillage est réalisée par l'utilisation d'unfiltre de lumière visible escamotable placé devant une caméra balayant l'écran de présentation du champ. Ce filtre escamotable bénéficie de deux positions: une première position dans laquelle la caméra détecte le point d'impact sur l'écran du faisceau laser et une seconde position, passive, où le filtre est enlevé et où la caméra reproduit le paysage et la cible vue par le tireur. Des moyens électroniques tels qu'un microprocesseur permettent de retranscrire le point d'impact sur un écran vidéo.The present invention therefore aims to produce a training device for indoor shooting having simple apparatus which can be easily installed and making it possible to obtain a visualization of the point of impact on a video screen presenting the shooting range visible to the shooter. This simplification of apparatus is achieved by the use of a retractable visible light filter placed in front of a camera scanning the screen presenting the field. This retractable filter has two positions: a first position in which the camera detects the point of impact on the screen of the laser beam and a second position, passive, where the filter is removed and where the camera reproduces the landscape and the target seen by the shooter. Electronic means such as a microprocessor make it possible to transcribe the point of impact on a video screen.
La présente invention a donc pour objet un dispositif pour l'entraînement au tir en salle comportant:
- 1) des moyens de projection sur un écran pour présenter à la vue d'au moins un tireur des images en défilement en lumière visible, représentant un champ avec au moins une cible à atteindre;

- b) des moyens d'arrêt placés sous la commande du dispositif de mise à feu, pour définir un instant d'arrêt du défilement des images projetées sur une image visible immobilisée,
- c) des moyens de détermination de la position du faisceau infrarouge sur ladite image immobilisée,
- d) des moyens d'incrustation électronique d'une figuration visible de cette position sur ladite image vidéo de l'image immobilisée,
caractérisé en ce qu'il comporte en outre un filtre escamotable de lumière visible transmettant seulement le faisceau infrarouge, interposé entre la caméra vidéo et les images en défilement devant le tireur et monté sur des moyens de basculement connectés audit ensemble électronique de commande, ledit filtre étant mobile par les moyens de basculement d'une position active de passage sélectif du faisceau infrarouge à une position passive hors du champ de la caméra vidéo, le basculement étant commandé par l'ensemble électronique à partir de l'arrêt du défilement de l'image dès que le faisceau infrarouge, après transmission, a été détecté par la caméra vidéo et que la détermination de sa position a été effectuée.
- 1) projection means on a screen for presenting to the view of at least one shooter scrolling images in visible light, representing a field with at least one target to be reached;
- 2) at least one weapon equipped with a firing device by the shooter and an infrared beam emitter;
- 3) a video camera for reproducing a video image of the image scrolling past the shooter;
- 4) a video screen for viewing said video image;
- 5) an electronic control unit comprising a microprocessor computer constituting:
- a) means for controlling the emission of the infrared beam by the firing device so as to simulate, by the infrared beam, a projectile,
- b) stop means placed under the control of the firing device, to define an instant of stop of the scrolling of the images projected on an immobilized visible image,
- c) means for determining the position of the infrared beam on said immobilized image,
- d) means for electronically inserting a visible figuration of this position on said video image of the immobilized image,
characterized in that it further comprises a retractable visible light filter transmitting only the infrared beam, interposed between the video camera and the images moving past the shooter and mounted on tilting means connected to said electronic control assembly, said filter being mobile by the means of tilting from an active position for selective passage of the infrared beam to a passive position outside the field of the video camera, the tilting being controlled by the electronic assembly from the stop of the scrolling of the image as soon as the infrared beam, after transmission, has been detected by the video camera and its position has been determined.
Le dispositif selon l'invention comporte un certain nombre d'éléments qui sont connus et utilisés de manière classique dans des applications similaires. Ainsi, il comporte des moyens de projection à défilement d'images, de type caméra, pour présenter à la vue du tireur l'image visible d'un champ sur lequel se trouve au moins une cible à atteindre, qu'elle soit fixe, ou évolutive sur un paysage.The device according to the invention comprises a certain number of elements which are known and used conventionally in similar applications. Thus, it includes image scrolling projection means, of the camera type, for presenting to the shooter's view the visible image of a field on which there is at least one target to be reached, whether it is fixed, or evolving on a landscape.
En ce qui concerne ces moyens de projection, un des avantages de l'invention est qu'il n'est pas nécessaire de disposer d'un enregistrement d'images de type particulier. Un simple enregistrement cinématographique sur film courant convient parfaitement, de même qu'un enregistrement.As regards these projection means, one of the advantages of the invention is that it is not necessary to have a recording of images of a particular type. A simple cinematographic recording on current film is perfectly suitable, as is a recording.

En ce qui concerne ces moyens de projection, un des avantages de l'invention est qu'il n'est pas nécessaire de disposer d'un enregistrement d'images de type particulier. Un simple enregistrement cinématographique sur film courant convient parfaitement, de même qu'un enregistrement vidéo. Dans un cas comme dans l'autre, on peut projeter la cible (ou les cibles s'il y en a plusieurs), à partir d'un enregistrement différent de celui du paysage, que l'on superpose sur le paysage à la projection, le paysage lui-même pouvant être fixe et reproduit d'une prise de vue unique, ou mobile sur des images successives. Mais l'on préférera souvent la solution plus simple consistant à projeter un paysage filmé à l'avance sur lequel évoluaient une ou plusieurs cibles au moment de la prise de vue.As regards these projection means, one of the advantages of the invention is that it is not necessary to have a recording of images of a particular type. A simple cinematographic recording on current film is perfectly suitable, as is a video recording. In either case, we can project the target (or targets if there are several), from a recording different from that of the landscape, which we superimpose on the landscape at the projection , the landscape itself can be fixed and reproduced from a single shot, or mobile on successive images. But we will often prefer the simpler solution consisting in projecting a landscape filmed in advance on which one or more targets were moving at the time of the shooting.
De préférence, il est prévu des moyens pour imposer un délai prédéterminé entre la mise à feu et l'arrêt du défilement d'images, de manière à simuler par ce délai le temps que mettrait le projectile ou le missile tiré, dans la réalité, à parcourir la distance séparant l'arme de la cible. Ce délai peut être lui-même déterminé par un calculateur, à partir de données qui peuvent être, soit introduites par exemple par l'instructeur, soit disponibles sous forme codée sur l'une des pistes magnétiques du film projeté destinée normalement au son.Preferably, means are provided for imposing a predetermined delay between firing and stopping the scrolling of images, so as to simulate by this delay the time that would take the projectile or the missile launched, in reality, to cover the distance between the weapon and the target. This delay can itself be determined by a computer, on the basis of data which can either be entered for example by the instructor or available in coded form on one of the magnetic tracks of the projected film normally intended for sound.
Avec sa grande simplicité, le dispositif de l'invention constitue néanmoins un outil de grande précision, par le fait que c'est le même équipement qui assure la détection, sur le même écran, de l'image projetée du paysage et de la cible et du point d'impact du coup tiré. Les informations correspondantes se retrouvent dans le même signal vidéo pour la reconstitution des images superposées et les erreurs de dérive, position, linéarité sont sans incidence sur l'appréciation des résultats du tir. Les réglages initiaux du système sont pratiquement inexistants. Tous ces avantages sont obtenus sans qu'il soit besoin de faire emploi d'un film de conception spéciale pour la projection.With its great simplicity, the device of the invention nevertheless constitutes a tool of great precision, by the fact that it is the same equipment which ensures the detection, on the same screen, of the projected image of the landscape and of the target. and the point of impact of the shot. The corresponding information is found in the same video signal for the reconstruction of the superimposed images and the errors of drift, position, linearity have no effect on the assessment of the results of the shooting. Initial system settings are virtually nonexistent. All these advantages are obtained without the need to use a film of special design for projection.
Selon une autre caractéristique de l'invention, le dispositif d'entraînement comporte des moyens pour corriger de manière prédéterminée soit la direction du faisceau infrarouge par rapport à la visée de l'arme, lors de la mise à feu, soit de préférence, la position de la trace du faisceau détectée sur l'image immobilisée lors de son incrustation dans l'image vidéo. Cette disposition permet notamment de prendre en compte l'incidence qu'aurait la balistique du projectile sur le résultat du tir simulé s'il était réel.According to another characteristic of the invention, the drive device comprises means for correcting, in a predetermined manner, either the direction of the infrared beam relative to the aim of the weapon, during firing, or preferably, the position of the beam trace detected on the immobilized image when it is embedded in the video image. This provision makes it possible in particular to take into account the impact that the ballistics of the projectile would have on the result of the simulated shot if it were real.
On remarquera par ailleurs que la trace du faisceau infrarouge que l'on détecte et dont on incruste une figuration dans l'image immobilisée, peut être soit ponctuelle (et figurée par une croix par exemple), soit linéaire et constituée par plusieurs points détectés à des instants différents avant l'immobilisation de l'image, pour matérialiser les positions d'un missile.It will also be noted that the trace of the infrared beam which is detected and whose figuration is embedded in the immobilized image, can be either punctual (and represented by a cross for example), or linear and constituted by several points detected at different moments before the immobilization of the image, to materialize the positions of a missile.
Comme on l'a déjà laissé entendre, l'emploi d'un calculateur approprié permet de prendre en compte dans le résultat du tir des informations diverses, telles que les particularités de l'arme utilisée et les caractéristiques balistiques de la munition simulée correspondante, des perturbations aérologiques, des informations relatives aux cibles (distance, position, déplacement, encombrement, ou autre). Des informations de ce genre peuvent provenir de l'appareil de projection, qui les contient par exemple sur l'une des pistes sonores du film.As has already been suggested, the use of an appropriate calculator makes it possible to take into account in the firing result various information, such as the particularities of the weapon used and the ballistic characteristics of the corresponding simulated ammunition, aerological disturbances, information relating to the targets (distance, position, displacement, congestion, or other). Information of this kind can come from the projection device, which contains it for example on one of the sound tracks of the film.
Le dispositif de l'invention peut encore présenter d'autres particularités avantageuses, ainsi qu'il ressortira de la description ci-après. On y décrit le dispositif dans un mode de réalisation particulier, choisi à titre d'exemple non limitatif, en faisant référence aux figures des dessins annexés dans lesquels:
- - La figure 1 représente schématiquement l'ensemble des organes essentiels constituant le dispositif d'entraînement au tir.
- - La figure 2 est un schéma synoptique dans lequel on a détaillé les fonctions assurées à l'intérieur du calculateur.
- - Figure 1 schematically represents the seems essential organs constituting the shooting training device.
- - Figure 2 is a block diagram in which we have detailed the functions performed inside the computer.
Sur la figure 1, on voit représenté un écran de visualisation d'images (1), un projecteur (2), de tout type classique tel qu'utilisé en cinéma pour la projection de films impressionnés d'images évolutives, et raccordé à un baffle de sonorisation (18), une caméra vidéo (3), et un fusil (4), dont le canon porte un émetteur laser (5), capable d'émettre sur commande un pinceau de lumière infra-rouge par impulsions.In Figure 1, there is shown an image viewing screen (1), a projector (2), of any conventional type as used in cinema for the projection of films impressed with evolving images, and connected to a sound baffle (18), a video camera (3), and a rifle (4), the barrel of which carries a laser transmitter (5), capable of emitting on command a brush of infrared light by pulses.
Tous ces éléments sont orientés vers le même écran (1). La focalisation du projecteur (2) est réglée pour produire une image nette sur l'écran (1), la caméra (3) reprend l'image diffusée par l'écran et la transcrit par balayage dans une image vidéo, le fusil est orienté manuellement par le tireur pour viser une cible apparaissant sur l'écran. La disposition illustrée à titre d'exemple suppose que cette cible est intégrée dans le film cinématographique projeté, qui représente un paysage dans lequel elle évolue. Naturellement, le même paysage peut aussi bien contenir plusieurs cibles parmi lesquelles le tireur choisira. Mais la ou les cibles pourraient également provenir d'un projecteur différent pour être projetées sur le même écran en superposition avec par exemple un paysage fixe issu d'un projecteur de diapositives. Selon d'autres variantes qui font partie de l'invention, le projecteur cinématographique pourrait être remplacé par un projecteur vidéo, commandé par un signal vidéo contenant toutes les informations relatives au paysage et à la cible pour reconstituer les images correspondantes sur l'écran (1). Et tant l'image de paysage que l'image de cible (ou l'une seulement des deux) peuvent provenir d'images d'objets réels préalablement enregistrés, ou peuvent être produites par synthèse électronique dans le signal vidéo.All these elements are oriented towards the same screen (1). The focus of the projector (2) is adjusted to produce a clear image on the screen (1), the camera (3) takes the image broadcast by the screen and scans it into a video image, the rifle is aimed manually by the shooter to aim at a target appearing on the screen. The arrangement illustrated by way of example supposes that this target is integrated into the projected cinematographic film, which represents a landscape in which it evolves. Naturally, the same landscape may as well contain several targets from which the shooter will choose. But the target (s) could also come from a different projector to be projected on the same screen superimposed with, for example, a fixed landscape from a slide projector. According to other variants which form part of the invention, the cinematographic projector could be replaced by a video projector, controlled by a video signal containing all the information relating to the landscape and to the target in order to reconstruct the corresponding images on the screen ( 1). And both the landscape image and the target image (or only one of the two) can come from images of real objects previously recorded, or can be produced by electronic synthesis in the video signal.
Selon d'autres variantes le projecteur de cinéma peut être remplacé par un projecteur de diapositives pour le fond paysage, les cibles et la figuration des impacts étant générés synthétiquement par un projecteur vidéo et superposés au paysage sur l'écran 1.According to other variants, the cinema projector can be replaced by a slide projector for the landscape background, the targets and the impact figuration being generated synthetically by a video projector and superimposed on the landscape on the screen 1.
Les mêmes éléments sont tous reliés fonctionnellement à un ensemble électronique de commande, constitué par un calculateur (8) à microprocesseurs, associé à un pupitre de commande (15) placé entre les mains de l'instructeur qui guide les exercices. Un casque à écouteurs (9), également placé sous la commande du calculateur (8), peut être utilisé pour faire entendre au tireur un son évoquant un tir réel au moment où il manoeuvre la gâchette du fusil (14) pour déclencher un tir fictif. En plus de la transmission des ordres de commande qui seront expliqués plus loin, le calculateur (8) sert essentiellement au traitement des signaux vidéo. Ainsi, il analyse en permanence le signal en provenance de la caméra vidéo (3), tandis qu'il détermine le signal qui commande la projection des images sur un écran de télévision (11). Ce dernier est disposé pour être observable par l'instructeur, et de préférence également par le ou les tireurs, de manière à leur permettre d'apprécier les résultats du tir. En cas de plus d'un tireur, plusieurs moniteurs vidéo peuvent être branchés en parallèle.The same elements are all functionally connected to an electronic control unit, constituted by a computer (8) with microprocessors, associated with a control console (15) placed in the hands of the instructor who guides the exercises. A headset (9), also placed under the control of the computer (8), can be used to make the shooter hear a sound evoking a real shot when he operates the trigger of the rifle (14) to trigger a fictitious shot . In addition to the transmission of control orders which will be explained later, the computer (8) is essentially used for processing video signals. Thus, it continuously analyzes the signal from the video camera (3), while it determines the signal which controls the projection of the images on a television screen (11). The latter is arranged to be observable by the instructor, and preferably also by the shooter (s), so as to allow them to appreciate the results of the shooting. If there is more than one shooter, several video monitors can be connected in parallel.
En effet, le dispositif que l'on décrit ici dans un mode de réalisation relativement simple, où il est exploité par un seul tireur actionnant un seul fusil, peut être modifié dans des conceptions évidentes pour l'homme de l'art, pour s'adapter à plusieurs tireurs travaillant avec le même instructeur. Si nécessaire, on peut prévoir dans ce cas, de distinguer les résultats des différents tirs effectués par les différents tireurs, soit par le fait que ceux-ci visent des cibles différentes, soit en figurant sur l'écran de télévision (11) des points d'impact provenant de tirs différents par des symbolisations différentes, soit encore en assignant aux émetteurs laser des différents fusils des codages différents des trains d'impulsions laser qui sont reconnus par le calculateur lors du tir. Naturellement, on doit entendre également que les fusils peuvent être remplacés par toute autre sorte d'arme adaptée à un entraînement en salle.Indeed, the device which is described here in a relatively simple embodiment, where it is operated by a single shooter actuating a single rifle, can be modified in designs obvious to those skilled in the art, for s '' adapt to several shooters working with the same instructor. If necessary, provision may be made in this case to distinguish the results of the different shots fired by the different shooters, either by the fact that they are aimed at different targets, or by appearing on the television screen (11) impact from different shots by different symbolizations, or by assigning to the laser emitters of the different rifles different codings of the laser pulse trains which are recognized by the computer during the firing. Of course, it should also be understood that the rifles can be replaced by any other kind of weapon suitable for indoor training.
Dans le cas des figures illustrant la présente description, on a aussi représenté une seule caméra vidéo. Cette caméra (3) est équipée d'un filtre escamotable (12). Il s'agit d'un filtre absorbant la lumière visible, qui est choisi pour se laisser traverser sélectivement par les rayonnements de la même gamme de longueurs d'ondes que le rayon produit par l'émetteur laser. On peut admettre à titre d'exemple, qu'il s'agit de rayons infra-rouges de 0,9 microns. En position active, le filtre (12) se trouve interposé devant l'objectif de la caméra, laquelle est donc sensible exclusivement à ce rayonnement infrarouge. Par contre, le filtre est monté sur l'axe d'un électro-aimant rotatif (13) placé sous la commande du calculateur, qui permet d'escamoter le filtre en le faisant basculer à l'écart du trajet des rayons lumineux entre l'écran de projection et la camera. Ce basculement du filtre est commandé par le calculateur (8), en même temps que celui-ci commande également le déclenchement de l'émission laser lors du départ du coup, avec cependant entre les deux un délai suffisant pour que le rayon laser réfléchi par l'écran soit reçu par la caméra et détecté dans le signal vidéo, avant le basculement du filtre.In the case of the figures illustrating the present description, a single video camera has also been shown. This camera (3) is equipped with a retractable filter (12). It is a visible light absorbing filter, which is chosen to be selectively traversed by radiation of the same wavelength range as the ray produced by the laser emitter. As an example, it can be assumed that these are 0.9 micron infrared rays. In the active position, the filter (12) is interposed in front of the camera lens, which is therefore sensitive exclusively to this infrared radiation. On the other hand, the filter is mounted on the axis of a rotary electromagnet (13) placed under the control of the computer, which allows the filter to be retracted by tilting it away from the path of the light rays between the projection screen and camera. This tilting of the filter is controlled by the computer (8), at the same time as the latter also controls the triggering of the laser emission at the start of the shot, with however between the two sufficient time for the laser beam reflected by the screen is received by the camera and detected in the video signal, before the filter switches over.
On comprend que de ce fait, la détection par la caméra (3) et l'analyse du signal vidéo par le calculateur permettent dans une première étape, de déceler la position de la trace du rayon laser sur l'écran de projection et d'en déterminer les coordonnées, avant d'analyser, dans une seconde étape, l'ensemble des informations relatives à l'image projetée par le projecteur (2), dans au moins tout le domaine des rayonnements lumineux visibles. Cette projection a néanmoins lieu, sur l'écran (1), pendant la totalité du temps où le tireur prépare sa visée, avant le départ du coup. Pour éviter de troubler l'image perçue alors par la caméra en rayonnement infra-rouge, il peut être souhaitable de disposer devant le projecteur, un filtre (16) d'absorption des rayonnements infra-rouges qui élimine ces derniers, au moins dans la gamme des longueurs d'ondes que laisse passer le filtre (12) placé devant la caméra.It is understood that therefore, the detection by the camera (3) and the analysis of the video signal by the computer make it possible, in a first step, to detect the position of the trace of the laser beam on the projection screen and to determine the coordinates, before analyzing, in a second step, all of the information relating to the image projected by the projector (2), in at least the entire field of visible light radiation. This projection has nevertheless place, on the screen (1), during the entire time when the shooter prepares for aiming, before the start of the shot. To avoid disturbing the image then perceived by the camera in infrared radiation, it may be desirable to have in front of the projector, a filter (16) for absorbing infrared radiation which eliminates the latter, at least in the range of wavelengths that passes the filter (12) placed in front of the camera.
Au moment du départ du coup, le calculateur (8) commande en outre l'arrêt du défilement du film dans le projecteur, de sorte que dans les images projetées, aussi bien le paysage que la cible restent ensuite fixés dans la position qui était la leur au déclenchement du tir. C'est cette image immobilisée qui est traduite dans le signal vidéo et retransmise par le calculateur au moniteur, pour visualisation sur l'écran de télévision (11). Le calculateur y fait apparaître en outre, par incrustation dans le signal vidéo, une figuration symbolique du point d'impact, une croix par exemple, dans la position précédemment déterminée par le calculateur pour la trace du pinceau laser. Sur l'écran de télévision, l'instructeur et le tireur peuvent donc observer les résultats du tir et en discuter tout à loisir, sur l'image du paysage et de la cible figée au moment du coup.At the time of the start of the shot, the computer (8) also controls the stopping of the film running in the projector, so that in the projected images, both the landscape and the target then remain fixed in the position which was the them when the shot is fired. It is this immobilized image which is translated into the video signal and retransmitted by the computer to the monitor, for viewing on the television screen (11). The calculator also displays there, by overlaying in the video signal, a symbolic figuration of the point of impact, a cross for example, in the position previously determined by the calculator for the trace of the laser brush. On the television screen, the instructor and the shooter can therefore observe the results of the shooting and discuss them at leisure, on the image of the landscape and the target frozen at the time of the shot.
Dans la version qui a été décrite jusqu'ici, le dispositif de l'invention convient sans restriction pour l'entraînement à l'emploi d'armes telles que des fusils, produisant des projectiles à balistique directe, sur des distances dont on peut négliger l'incidence. Mais divers perfectionnements peuvent être apportés à ce dispositif pour l'adapter à d'autres usages.In the version which has been described so far, the device of the invention is suitable without restriction for training in the use of weapons such as rifles, producing direct ballistic projectiles, over distances which can be neglected. incidence. However, various improvements can be made to this device to adapt it to other uses.
Dans le cas d'un tir au moyen de lancero- quettes, on a intérêt à tenir compte de la hausse introduite par la trajectoire balistique, ainsi que de la distance parcourue par le projectile. La simulation de l'effet de distance peut être assurée en programmant le calculateur pour qu'il impose à l'arrêt de la projection des images de paysage et de cible, un retard à compter du départ du coup correspondant au temps de parcours du projectile sur la distance évaluée au préalable, soit par indication directe de l'instructeur, soit par lecture d'informations codées en provenance du film de projection ou autre support d'image. Quant à la simulation de la balistique, elle peut être effectuée en corrigeant de la valeur de la flèche, calculée pour cette distance, la position du point d'impact entre sa détection par la caméra lors de l'émission du pinceau laser et sa figuration symbolique dans la visualisation sur l'écran video. Différentes perturbations aero- logiques ou autres influant sur la trajectoire du projectile peuvent être également introduites. Un codage adéquat des impulsions laser pour chaque type d'arme dont le tir est simulé permet au calculateur d'appliquer les corrections balistiques correspondantes; il est possible ainsi de simuler simultanément des tirs déclenchés à partir d'armes différentes.In the case of a shot using lancets, it is advantageous to take into account the increase introduced by the ballistic trajectory, as well as the distance traveled by the projectile. The simulation of the distance effect can be ensured by programming the calculator so that it imposes at the end of the projection of the landscape and target images, a delay from the start of the shot corresponding to the travel time of the projectile over the distance evaluated beforehand, either by direct indication from the instructor, or by reading coded information from the projection film or other image support. As for the ballistics simulation, it can be carried out by correcting the value of the arrow, calculated for this distance, the position of the point of impact between its detection by the camera during the emission of the laser brush and its figuration symbolic in the display on the video screen. Different aerological or other disturbances influencing the trajectory of the projectile can also be introduced. Adequate coding of the laser pulses for each type of weapon whose firing is simulated allows the computer to apply the corresponding ballistic corrections; it is thus possible to simulate simultaneously shots fired from different weapons.
Dans d'autres variantes, on peut avoir intérêt à utiliser des trains d'impulsions successifs de l'émission laser. En particulier, si l'arme est supposée tirer un missile que le tireur peut guider par rapport à l'axe de visée, l'enregistrement par la caméra des traces produites sur l'écran de projection par ces impulsions laser successives permet une mémorisation continue du tracé correspondant au réticule de visée, et l'on peut faire apparaître ce tracé complet, par incrustation dans le signal vidéo, sur le paysage reproduit avec la cible dans sa position au moment de l'impact. Des impulsions laser successives peuvent également servir à simuler un tir par rafales. On peut par exemple produire des trains d'impulsions laser au rythme d'un tir de mitraillette, et assurer l'incrustration dans le signal vidéo en figurant les différents points d'impact. Comme l'image du paysage est figée, que sa position immobilisée soit celle du début ou celle de la fin du tir, ceci implique que l'on néglige l'évolution de la cible ou des cibles pendant le temps de la rafale.In other variants, it may be advantageous to use successive pulse trains of the laser emission. In particular, if the weapon is supposed to fire a missile that the shooter can guide relative to the line of sight, the recording by the camera of the traces produced on the projection screen by these successive laser pulses allows continuous memorization of the line corresponding to the aiming reticle, and one can make this complete line appear, by overlay in the video signal, on the landscape reproduced with the target in its position at the time of impact. Successive laser pulses can also be used to simulate a burst fire. It is possible, for example, to produce laser pulse trains at the rate of a submachine gun fire, and to insure the video signal by showing the various points of impact. As the image of the landscape is frozen, whether its immobilized position is that of the beginning or that of the end of the shooting, this implies that one neglects the evolution of the target or targets during the time of the burst.
Le point d'impact dont il est question tout au long de la description correspond au point de passage du projectile dans le plan vertical situé au niveau de la cible et perpendiculaire à l'axe de visée tireur-cible.The point of impact which is mentioned throughout the description corresponds to the point of passage of the projectile in the vertical plane located at the level of the target and perpendicular to the axis of aiming shooter-target.
Dans une forme de réalisation perfectionnée du dispositif décrit, le système de projection est pourvu d'un filtre optique (17) attenuateur de lumière, qui permet de simuler une ambiance nocturne, sur commande de l'instructeur. Il est alors interposé devant l'objectif pendant la visée par le tireur, mais il est escamoté après le tir, de sorte que la caméra fournisse une image pleinement éclairée pour l'observation du résultat du tir. Une commande accessible sur le pupitre permet à l'instructeur de commander son positionnement par l'intermédiaire d'un électro-aimant rotatif (18).In an improved embodiment of the device described, the projection system is provided with an optical filter (17) attenuating light, which makes it possible to simulate a night atmosphere, on command of the instructor. It is then interposed in front of the objective during the aiming by the shooter, but it is retracted after the shooting, so that the camera provides a fully lit image for the observation of the result of the shooting. A control accessible on the desk allows the instructor to control its positioning by means of a rotary electromagnet (18).
Par ailleurs, le dispositif peut être équipé de divers mécanismes au niveau de l'arme pour simuler des effets particuliers. A titre d'exemple, un effet de recul au moment du tir peut être apporté par un mouvement de l'arme déclenché à la mise à feu. Un déplacement par secousse peut être obtenu notamment par une masse vibrante montée sur l'arme et commandée par un électro-aimant ou par une injection d'air.In addition, the device can be equipped with various mechanisms at the level of the weapon to simulate particular effects. For example, a recoil effect at the time of firing can be brought about by a movement of the weapon triggered upon firing. A movement by shaking can be obtained in particular by a vibrating mass mounted on the weapon and controlled by an electromagnet or by an injection of air.
Enfin, si l'on s'est surtout intéressé dans l'exemple particulier décrit et représenté, au cas où il y a effectivement arrêt du défilement des images de la projection au moment du tir, ce cas n'est pas limitatif dans une variante qui se révèlera souvent avantageuse, notamment dans le cas d'un entraînement simultané de plusieurs tireurs, l'image immobilisée n'est pas examinée dès le tir, mais elle est enregistrée. En même temps que l'image vidéo de l'image immobilisée, définie par le même instant d'arrêt que dans la variante avec arrêt effectif, on enregistre toutes les informations nécessaires pour caractériser le tir correspondant et les données d'incrustation relatives à l'impact. Le défilement n'est pas arrêté et l'inscription se poursuit pour plusieurs tirs effectués par le même tireur ou par des tireurs différents. Les résultats des tirs sont examinés par l'instructeur et les élèves dans une étape ultérieure où l'on fait redéfiler l'ensemble du film. C'est alors que l'arrêt du défilement est effectivement commandé à l'instant correspondant à chaque tir pour permettre l'examen de la position de l'impact incrusté sur l'image immobilisée.Finally, if we were mainly interested in the particular example described and represented, in the event that the scrolling of the images of the projection actually stops at the time of the shooting, this case is not limiting in a variant. which will often prove to be advantageous, in particular in the case of a simultaneous training of several shooters, the immobilized image is not examined on firing, but it is recorded. At the same time as the video image of the immobilized image, defined by the same stop instant as in the variant with effective stop, all the information necessary to characterize the corresponding shot and the overlay data relating to the image are recorded. 'impact. Scrolling is not stopped and registration continues for several shots fired by the same shooter or by different shooters. The results of the shots are examined by the instructor and the students in a later stage where the entire film is re-screened. It is then that the stop of the scrolling is effectively commanded at the instant corresponding to each shot to allow the examination of the position of the encrusted impact on the immobilized image.
