Definitions

  • the present invention relates to a device for electronic and automatic determination of the accuracy of a shooting shooter in light shooting. Furthermore, the present invention relates to a firearm with a light source whose trigger is connected to the light source. The present invention also relates to an evaluation system that determines the accuracy of a shooter from the information of the detected signal.
  • a light source for example a laser
  • the shooter points the rifle, and thus the laser, at a target.
  • the light beam is detected when the trigger of the weapon is operated. From the position of the light spot can be determined with a detector, the position of the light spot on the target.
  • An evaluation unit can determine the position of the light spot relative to the ideal match position.
  • the advantage of this solution is on the one hand, that the accuracy of a shooter can be determined inexpensively, since no consumables such as a bullet must be used and also the target is not damaged by a bullet.
  • the optical measurement has the advantage of high measurement accuracy.
  • Such an optical measuring system for determining the accuracy of a shooter is for example from the WO 92/08093 known.
  • German patent application DE 40 07 759 A1 proposed a system in which the laser signal has a coding, for example to determine which contactor has hit the target.
  • German patent DE 42 25 074 C1 a device proposed to control the shutter of a CCD camera with a modulated light beam.
  • the light signal is modulated.
  • a first camera detects the modulated light beam.
  • the shutter of a second camera is opened and the Position of the light signal is measured with a second camera.
  • the hit position in real shooting is influenced by the path of the projectile.
  • the path of a projectile can be described by different temporal successive phases. In each of these phases, the path of the projectile is changed by external influences. For example, the path of the projectile is affected by the movement of the firearm at the time the shot is fired. Any acceleration or constant motion results in momentum transfer to the projectile.
  • the further path of the projectile is influenced by the fact that the bullet is guided through the barrel of the firearm. In addition, due to gravity, a changed trajectory occurs as soon as the projectile has left the barrel.
  • the present invention is based on the idea to design a device for determining the accuracy of a shooter so that a radiation source is mounted on a firearm with a trigger.
  • the trigger has at least two positions and the trigger is connected to the radiation source.
  • the radiation source emits a modulated light beam, the modulated light beam containing information about the position of the trigger.
  • the device includes at least one detector for detecting the modulated light beam.
  • the device comprises an evaluation unit which evaluates the detected and modulated light beam. From the detected position and the information about the position of the trigger an evaluation signal is generated, which contains information about the accuracy of the shooter.
  • the modulated light beam contains information about the position of the trigger, Influences on the trajectory, such as those created during real shooting with a projectile, can be taken into account. This makes it possible that from the detected data during light shooting a hit position can be determined, which is equivalent to the hit position when shooting with a bullet.
  • the accuracy of the shooter can be trained from the information about the location and the information about the position of the trigger.
  • a real shot consists of different shots that correlate with positions of the trigger.
  • modulating the light signal depending on the position of the trigger individual firing phases can be identified and evaluated. Based on this data, a shooter can optimize each firing phase and thus train the accuracy efficiently.
  • a first position of the trigger corresponds to a neutral position of the trigger and a second position of the trigger to a position at which a pressure point of the trigger is reached. From the first neutral position of the trigger, the phase of the shot in which the shooter seeks the target can be evaluated. From the second position of the trigger the phase of the shot can be examined, in which the shooter has the target in sight.
  • a third position of the trigger corresponds to a position at which a shot is fired during real shooting, and a fourth position to trigger a position after the triggering of a shot.
  • From the third position of the trigger information can be collected on how the rifle behaves during the firing of the shot. From the fourth position the behavior of the rifle can be analyzed.
  • the movement of the position of the light spot on the target between the triggering of the shot and the free flight of a projectile also referred to as the retention time, can be taken into account in light shooting.
  • it can be taken into account by another freely adjustable time how gravity would influence a real projectile when it is no longer guided by the weapon barrel.
  • Easier detection of the light beam is possible when the light beam is aligned, and is preferably a parallel light beam.
  • the radiation source is a laser.
  • the evaluation of the position of the light spot can be improved.
  • the radiation source emits a light beam with a Wellenläge from the ultraviolet, visual or infrared spectral range.
  • An optical visible light beam may be advantageous because the shooter sees where the light beam is incident.
  • an optically visible light beam allows shooters to be trained with little experience.
  • a beam of light from the non-visible area can be advantageous if experienced shooters are to be trained. The point of light is not visible to the shooter and thus shooting can be realistically trained as with a real bullet.
  • the modulation of the light beam is advantageously carried out via a change in the pulse duration of the light beam and / or the change in the wavelength of the emitted radiation.
  • the apparatus may further comprise a target arranged such that the shooter sends the light beam to the target for ascertaining the accuracy. This makes it possible that the shooter is given a clear goal.
  • At least one detector comprises a target.
  • the detector surface is used as a target and for detecting the position and / or the detection of the modulated information of the light beam.
  • the precision can be increased since no optics is necessary for detecting the position of the light beam on the detector. Consequently, errors caused by the use of optics can be avoided.
  • detecting the modulation of the light beam it is possible to avoid errors caused by air riots between the target and the detector.
  • the firearm can additionally fire a projectile. This makes it possible to calibrate the hit position during shooting based on the trajectory of a real projectile.
  • the target can electronically determine the position of the bullet through the bullet through a target area. Thus, these data can be transmitted for calibration in electronic form to the evaluation unit.
  • At least one detector of the device comprises a first camera.
  • the distance between the first camera and the target is adjustable and is at least 10 mm, maximum 100 mm and preferably 40 mm.
  • the device comprises a second camera, wherein the second camera has the same distance to the target as the first camera.
  • a first axis is determined by the first camera and the ideal hit position and a second axis determined by the second camera and the ideal hit position.
  • the angle between the first axis and the second axis is at least 45 °, a maximum of 135 °, preferably 90 °.
  • the system can be built flexibly and inexpensively.
  • a second camera allows the position of the light beam relative to the ideal target position to be detected in two independent axes with high precision.

  • FIG. 1 shows a schematic representation of the device for determining the accuracy of a shooter according to an advantageous embodiment of the present invention.
  • a radiation source also referred to as a light pointer
  • a firearm 100 such as a rifle or a pistol, or alternatively integrated into the firearm 100.
  • the firearm has a trigger 101 which is coupled to the radiation source. By coupling the trigger 101 with the radiation source the emitted light beam can be modulated in dependence on the position of the trigger 101.
  • the first position or neutral position of the trigger 101 there is a position in which the trigger 101 is not actuated, which is referred to as the first position or neutral position of the trigger 101.
  • a second position corresponds to a position when the pressure point of the trigger 101 is reached.
  • a third position of the trigger 101 can be achieved, which corresponds to the actual shooting a position of the trigger 101 when the shot is fired.
  • Another, fourth position of the trigger 101 corresponds in real shooting holding the trigger after the shot to release.
