Definitions

  • the device offers a means for automatic calibration of an optical sight for firearms, by firing one round only.
  • a firearm equipped with an optical sight typically a riflescope
  • an optical sight typically a riflescope
  • Several rounds are usually needed for a successful calibration.
  • Hunters then usually fire a couple of high priced soft point rounds to confirm the calibration.
  • the device described in this application offers shooters the possibility of getting the optical sight (riflescope) automatically calibrated, by firing one round only, at a defined target.
  • a beam-splitter (1) lets the shooter and the image processing system view the same scene.
  • the image is fed into a camera (2) (e.g. a CCD camera) for registration.
  • a micro-processor with sufficient memory and software (3) analyzes the image and determines the error (i.e. calculates the need for calibration).
  • Servo motors (4) with gears (5) can be used to operate the adjustment screws and the traditional mechanical cross-hair element (9).
  • a switch is used to initiate the automatic calibration sequence (6).
  • Lamps (8) (e.g. diodes) indicate the calibration result.
  • the device is powered by a built-in or external electrical power source (7).
  • cross-hairs is meant all existing variants of optical sights.
  • the calibration sequence is described by the following instruction to the shooter:
  • a target typically: a white square surface against a dark background
  • firing position at the range for which the firearm is to be calibrated.
  • the calibrating function is shut off by pressing the switch again.
  • the microprocessor and camera start up.
  • the camera immediately starts taking frames (with a typical interval between frames of 40 ms) and stores them in a FIFO queue (First hi , First Out).
  • the microprocessor detects that a round has been fired when the target suddenly disappears from the view (it happens very fast; i.e. from one frame to the other).
  • an embedded sensor can be used to register this event.
  • the last exposure before the shot is stored for later analysis; the edges of the white target area are identified by contrast with the darker background.
  • the shooter resumes the aiming position while the camera continues to take frames and to store them in the FIFO queue.
  • the best frame after firing is identified and is then compared with the best frame before firing.
  • the bullet hole position on the target is identified by variation in contrast (black dot on the white surface).
  • the microprocessor calculates the needed adjustment. This means both horizontal and vertical adjustments in "clicks", to align the bullet hole with the cross-hairs . Since the cross-hairs position is determined relative to the target in the entire field of view- both before and after firing the round - the needed adjustment can be calculated independent of range and riflescope magnification. (However, the target must not be moved and that the shooter must not change position during the calibration procedure).
  • the servo motors are then activated so that the adjustment screws are turned the needed number of "clicks" in both horizontal and vertical directions.
  • the mirror is moved between bi-stable positions by a lever on the outside of the sight, locked by form and/or friction.
  • a display typically a LCD - Liquid Crystal Display
  • the need for indicator lamps is eliminated since the calibration result can be displayed directly on the display.
  • the switch (6) and power source (7) are still needed.
  • the camera view is presented together with the cross ⁇ hairs as an all digital picture on the display. This fully eliminates the need for a mechanical adjustment of the cross-hairs, see sketch in figure 2.
  • the calibration procedure is carried out as described above.
  • a separate device attached to a traditional optical sight contains a camera and microprocessor and includes servo motors to be mounted onto the existing adjustment screws.
  • This variant can be used together with traditional sights without any modification, whenever a calibration is needed.
  • the variants can also be implemented as semi-automatic devices for adjustment of mechanical cross-hairs.
  • the device presents the shooter with information about the needed number of clicks, both in horizontal and vertical directions, to achieve alignment between the bullet hole and the cross-hairs.
  • the shooter then carries out the adjustment manually according to the information. (The information can be projected via the semi- transparent mirror onto the viewfinder).

Abstract

Le brevet définit un dispositif destiné à l'étalonnage automatique de viseurs optiques pour armes à feu. Un seul coup de feu doit être tiré pour obtenir le résultat désiré. Le dispositif peut être intégré avec un viseur optique ou installé en tant qu'unité séparée montée sur le viseur. Le dispositif comprend une caméra numérique (p.ex., un CCD), un diviseur de faisceau, un microprocesseur comprenant une mémoire pour images de caméra et un logiciel, ainsi que des servomoteurs comprenant un mécanisme de transmission, un commutateur électrique, des diodes lumineuses et un capteur de détection de coups de feu. Dans l'application de viseur numérique, le dispositif comprend également une unité d'affichage, sans servomoteurs ni mécanisme de transmission ni diodes lumineuses ni diviseur de faisceau. La procédure d'étalonnage consiste à tirer un coup de feu sur une cible se présentant comme une surface blanche rectangulaire sur un fond sombre à une distance voulue. La caméra sauvegarde la dernière image qui précède immédiatement le coup de feu et compare la position des fils croisés à celle d'une image suivante dans laquelle on peut trouver un point d'impact du projectile. Après les calculs, la position des fils croisés est ajustée par les servomoteurs de manière à s'aligner sur la position détectée du point d'impact du projectile. Dans l'application du viseur numérique, les fils croisés sont simplement 'tracés' dans une nouvelle position correcte à l'écran. L'arme à feu et le viseur optique sont alors calibrés à une distance choisie.
