Abstract
Translated fromFrenchDescription
Translated fromFrenchLa présente invention concerne un dispositif d'aide au tir sans visée avec une arme de petit calibre.The present invention relates to a device for shooting assistance without aiming with a small caliber weapon.
On constate dans les théâtres d'opération actuels qu'une majorité de tirs se font à courte distance et sans que le tireur ait le temps de viser pour engager sa cible.It is noted in current theaters of operation that a majority of shots are made at close range and without the shooter having the time to aim to engage his target.
Ces tireurs tirent donc sans visée, soit au jugé ou instinctivement, soit au pointé, c'est-à-dire en alignant leur arme en direction de la cible mais sans utiliser les organes de visée.These shooters therefore shoot without aiming, either by judgment or instinctively, or at aiming, that is to say by aligning their weapon in the direction of the target but without using the aiming organs.
Cependant, dans ces cas et surtout lors des tirs instinctifs, la majorité des tireurs ne touchent pas la cible, même à des distances inférieures à 10 m. Seuls certains tireurs entraînés qui "sentent" la position de leur arme par rapport à leur corps parviennent à des résultats convenables.However, in these cases and especially during instinctive shots, the majority of shooters do not hit the target, even at distances less than 10 m. Only certain trained shooters who "feel" the position of their weapon in relation to their body achieve satisfactory results.
Afin d'essayer de résoudre ce problème, des pointeurs laser simbleautés avec l'arme sont utilisés.In an attempt to solve this problem, laser pointers simulated with the weapon are used.
Le rayon laser n'est cependant plus visible par forte luminosité extérieure comme en plein soleil et/ou avec des cibles claires.However, the laser beam is no longer visible in strong outdoor light such as in direct sunlight and / or with clear targets.
Même par conditions de visibilité correctes, la portée du rayon laser, du moins celui dans le spectre visible, reste limitée dû à l'absorption.Even under correct visibility conditions, the range of the laser beam, at least that in the visible spectrum, remains limited due to absorption.
Une solution préconisée pour remédier à ces limitations consiste dans l'utilisation de rayons laser dans le spectre visible ou invisible, par exemple de rayons laser infrarouges, avec un système d'intensification de lumière pour voir le rayon dans la lunette de visée.One solution recommended to remedy these limitations consists in the use of laser rays in the spectrum. visible or invisible, for example from infrared laser rays, with a light intensification system to see the ray in the telescopic sight.
Cette solution ne fonctionne bien que de nuit. Elle permet alors de voir le rayon laser sur plusieurs centaines de mètres. Sous peine de détoriation majeure, de jour, la lunette de visée doit être protégée, ce qui diminue d'autant ses capacités.This solution only works well at night. It then allows you to see the laser beam over several hundred meters. Under penalty of major detoriation, during the day, the telescopic sight must be protected, which reduces its capacities accordingly.
En plus, cette solution est chère et nécessite un dispositif volumineux et lourd, ce qui en limite l'utilisation opérationnelle.In addition, this solution is expensive and requires a bulky and heavy device, which limits its operational use.
Actuellement, des systèmes sont développés qui mettent en oeuvre différentes techniques permettant la localisation relative de l'axe de visée de l'arme par rapport à la tête du tireur portant un casque à visière, et la projection de l'axe de visée sur la visière. Ces systèmes sont assez onéreux et nécessitent une liaison entre l'arme et le casque et un échange d'informations permanent entre ces deux entités.Currently, systems are developed which implement different techniques allowing the relative location of the aiming axis of the weapon relative to the head of the shooter wearing a helmet with visor, and the projection of the aiming axis on the visor. These systems are quite expensive and require a link between the weapon and the helmet and a permanent exchange of information between these two entities.
Le but de l'invention est de palier à ces inconvénients par un dispositif d'aide au tir sans visée qui est relativement simple et économique.The object of the invention is to overcome these drawbacks by a device for aiming without aiming which is relatively simple and economical.
Ce but est atteint, conformément à l'invention par un dispositif d'aide au tir sans visée comportant un pointeur laser placé sur l'arme et comportant également d'une part une micro caméra pourvue de moyens pour localiser le point d'impact du rayon laser du pointeur sur la cible par analyse du signal reçu, et d'autre part un dispositif de visualisation de ce point d'impact devant l'oeil du tireur, par exemple sur une visière sise devant l'oeil de ce tireur.This object is achieved, in accordance with the invention by a device for assisting in shooting without aiming comprising a laser pointer placed on the weapon and also comprising on the one hand a micro camera provided with means for locating the point of impact of the laser beam of the pointer on the target by analysis of the received signal, and on the other hand a device for displaying this point of impact in front of the shooter's eye, for example on a visor located in front of the eye of this shooter.
Bien que la micro caméra pourrait être montée sur l'arme, elle est de préférence montée sur le tireur, par exemple sur un casque ou un masque facial.Although the micro camera could be mounted on the weapon, it is preferably mounted on the shooter, for example on a helmet or a face mask.
Dans ce cas, aucune liaison n'est requise entre l'arme et le tireur.In this case, no connection is required between the weapon and the shooter.
Pour plus de clarté, un exemple de réalisation d'un dispositif d'aide au tir sans visée selon l'invention est décrit ci-après à titre illustratif et non restrictif, référence étant faite aux dessins annexés dans lesquels:
- la figure 1 est une vue schématique d'un dispositif d'aide au tir sans visée selon l'invention;
- la figure 2 représente l'image perçue par le tireur lors de l'utilisation du dispositif selon l'invention.
- Figure 1 is a schematic view of a shooting aid device without aiming according to the invention;
- FIG. 2 represents the image perceived by the shooter when the device according to the invention is used.
Le dispositif d'aide au tir sans visée selon l'invention représenté à la figure 1 comprend un premier sous-ensemble monté sur l'arme 1 et formé par un pointeur laser 2, et un deuxième sous-ensemble qui peut être monté sur l'arme mais est de préférence monté sur le tireur, plus particulièrement sur un casque 3 ou un masque facial porté par ce tireur, et qui comporte d'une part une micro caméra 4 et d'autre part un dispositif de visualisation 5.The aimless shooting aid device according to the invention shown in FIG. 1 comprises a first sub-assembly mounted on the weapon 1 and formed by a laser pointer 2, and a second sub-assembly which can be mounted on the weapon but is preferably mounted on the shooter, more particularly on a
Le pointeur laser 2 est d'une construction connue et n'est pas décrit en détail. Il peut être du type fonctionnant dans le spectre visible ou du type fonctionnnant dans le spectre invisible et a de préférence une puissance suffisante pour atteindre une portée d'au moins 100 à 150 mètres.The laser pointer 2 is of a known construction and is not described in detail. It can be of the type operating in the visible spectrum or of the type operating in the invisible spectrum and preferably has sufficient power to reach a range of at least 100 to 150 meters.
L'axe du pointeur laser 2 coïncide évidemment avec l'axe de visée de l'arme 1.The axis of the laser pointer 2 obviously coincides with the aiming axis of weapon 1.
La micro caméra 4, du type CCD ou autre, comprend des moyens pour localiser par analyse des signaux correspondant à l'image reçue, le point d'impact 6 du rayon laser 7 du pointeur laser 2 sur la cible 8.The
Ces moyens pour localiser le point d'impact par analyse peuvent être réalisés par des technologies existantes et ne sont donc pas décrits en détail.These means for locating the point of impact by analysis can be carried out by existing technologies and are therefore not described in detail.
Le dispositif de visualisation 5 est couplé à la micro caméra 4 pour recevoir l'information de cette caméra correspondant à la position de l'impact 6, et possède des moyens pour transmettre cette information au tireur en visualisant l'impact 6 devant son oeil, en particulier en projetant cet impact sous forme d'un réticule 9 sur un écran 10 transparent.The
Cet écran 10 est par exemple formé par une partie de la visière du casque 3 ou d'un masque facial ou est monté sur cette visière ou ce masque.This
Il existe une multitude de possibilités connues actuellement concernant la méthode de projection, par exemple à l'aide de diodes émettant de la lumière ou de cristaux liquides.There are a multitude of possibilities currently known regarding the projection method, for example using light-emitting diodes or liquid crystals.
Ce dispositif d'aide au tir sans visée travaille comme suit:This aimless shooting aid works as follows:
Le tireur dirige son arme 1 en direction de la cible 8 avec le dispositif d'aide au tir en marche, et le pointeur laser 2 projette un rayon laser 7 sur cette cible 8 ou ses environs immédiats.The shooter directs his weapon 1 towards the
La micro caméra 4 filme l'environnement ou le paysage devant le tireur et par conséquent également le rayon laser 7 et son point d'impact 6 sur la cible 8 ou ses environs immédiats.The
A l'aide de ses moyens de localisation par analyse du signal reçu, correspondant à l'image perçue, la micro caméra 4 retire la position de l'impact 6 et transmet cette position au dispositif de visualisation 5 qui projette devant l'oeil du tireur, c'est-à-dire sur l'écran 10, un réticule 9 à l'endroit correspondant à la position de l'impact 6.Using its localization means by analyzing the received signal, corresponding to the perceived image, the
Le tireur voit donc devant lui l'image représentée à la figure 6, c'est-à-dire, d'une part, la cible 8 et son environnement immédiat et éventuellement le rayon laser 7, par vision directe à travers la visière, et d'autre part, le réticule 9 projeté par le dispositif de visualisation 5 sur l'écran 10 situé dans son champ de vision.The shooter therefore sees in front of him the image represented in FIG. 6, that is to say, on the one hand, the
Le réticule 9 correspondant au point d'impact 6 du rayon laser 7 est juxtaposé à l'image que le tireur voit directement et marque son point de visée. Le tireur peut donc immédiatement corriger son tir.The reticle 9 corresponding to the point of
Si le rayon laser 7 est visible par le tireur, par exemple par temps sombre et/ou à courte portée, et le dispositif est bien réglé, l'impact 6 du rayon laser 7 apparaîtra dans le champ de vision du tireur au même endroit que le réticule 9.If the
Si le rayon laser n'est plus visible, seul le réticule 9 continuera à apparaître dans le champ de vision, pour autant évidemment que la micro caméra 4 détecte encore le rayon laser 7.If the laser beam is no longer visible, only the reticle 9 will continue to appear in the field of vision, provided that the
La détection par la micro caméra 4 peut éventuellement être améliorée par l'utilisation d'un ou plusieurs filtres mettant en évidence le rayonnement laser en filtrant d'autres fréquences du spectre.The detection by the
Si le pointeur laser 2 émet dans le spectre non visible, par exemple l'infra-rouge, le rayon laser 7 sera invisible pour le tireur mais visible pour la micro caméra 4 et le tireur verra dans son champ de vision le réticule 9.If the laser pointer 2 emits in the non-visible spectrum, for example the infrared, the
Le dispositif pourrait être utilisable de nuit si la micro caméra 4 ou une autre micro caméra donne au tireur également un image de nuit directe de la cible et de son environnement, par exemple sur la visière du casque 3, le réticule 9 étant juxtaposé à cette image de nuit.The device could be used at night if the
Aucune liaison matérielle n'est nécessaire entre les deux sous-ensembles susdits, c'est-à-dire entre le pointeur laser 2, d'une part, et la micro caméra 4 et le dispositif de visualisation 5, d'autre part.No hardware link is necessary between the two aforementioned sub-assemblies, that is to say between the laser pointer 2, on the one hand, and the
Il est évident que de nombreuses modifications peuvent être apportées aux exemples susdécrits, sans pour autant sortir du cadre de l'invention.It is obvious that many modifications can be made to the examples described above, without going beyond the ambit of the invention.
