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.
  • the invention proposes a device for indoor shooting training, in particular for training with an infantry weapon, an inexpensive device, light and of simple operation, in which only an infrared radiation emitter, reduced size, must be adapted on the weapon itself.
  • the device according to the invention comprises a certain number of elements which are known and used conventionally in similar applications.
  • 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.
  • the drive device comprises a device - for automatically stopping the scrolling of the projected images, to stop the projection on a visible immobilized image, and this device is placed under the command of the weapon firing device.
  • a device stops the scrolling of the images, and fixes the field of observation, landscape and target (s), in a position where the instructor and the shooter have all the time desirable to observe the result of the shot.
  • the immobilized visible image can only be recorded at a stop instant defined by the stop device or equivalent means, without there being any effective stop of the scrolling during the projection during from which the shot is made. The judgment will then be postponed to a subsequent projection corresponding to a study of the results of the shooting, this being especially useful in the event of multiple shots.
  • 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 according to the invention also differs in a characteristic manner from the previously known solutions, in the design of the means which analyze the results of the shots and transcribe them in front of the instructor or the shooter (s). It comprises video means for producing a video image of said immobilized image, and for selectively detecting the trace of the infrared beam on said immobilized image and determining its position in its video image, and means for electronically embedding a visible figuration of this position on said video image of the immobilized image.
  • the means for producing a video image of the immobilized image comprise a video camera which is arranged to observe the screen on which the field of projection is projected, either by especially the landscape with the target. Its role is to record the successive images in the video signal to transcribe them at the choice of the instructor, the latter having for example a television screen with his control monitor.
  • the retractable filter makes it possible to temporarily make the camera sensitive only to infrared rays, in the range of wavelengths of the rays produced by the laser emitter that the weapon carries, while the rest of the time it is sensitive to the projected image.
  • the device of the invention further comprises control means, which are actuated by the triggering of the shot and which determine, on the one hand the retraction of the above filter, on the other hand stop scrolling images.
  • control means which are actuated by the triggering of the shot and which determine, on the one hand the retraction of the above filter, on the other hand stop scrolling images.
  • 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 we detect 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 times before the image is immobilized, to materialize the positions of a missile.
  • an appropriate calculator allows to take into account in the result of the firing of 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 manually aimed 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 figuration of the impacts being generated synthetically by a video projector and superimposed on the landscape on the screen 1.
  • 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) for triggering 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 filter absorbing the visible light, 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 thereof, 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 nevertheless takes place, on the screen (1), during the entire time when the shooter prepares his aim, before 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.
  • 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 on the distance assessed 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 visualization 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 shot, this implies that we neglects the evolution of the target or targets during the burst time.
  • the point of impact in question 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 light attenuating filter, 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.
