Abstract (en)
[origin: WO2006041386A1] This patent defines a device for automatic calibration of optical sights for firearms . Only one shot has to be fired to achieve this. The device can be integrated with an optical sight or fitted as a separate unit mounted on the sight. The device consists of a digital camera (e.g. CCD), some kind of beam splitter, a microprocessor including a memory for camera images and computer software, servo motors including a gear mechanism, an electrical switch, light emitting diodes and a shot detecting sensor. In the digital sight application, the device also includes a display unit while servo motors, gear mechanism, light emitting diodes and beam splitter are excluded. The calibration procedure: involves firing a round at a target consisting of a rectangular white surfaceon a dark background at the chosen range. The camera saves the last image immediately before the firing moment and compares the cross-hairs position with that of a following image from which the projectile point of impact can be found. After calculations, the position of the cross-hairs is adjusted by servomotors to align with the detected projectile impact point position. In the digital sight application, the cross-hairs is simply "drawn" at the new correct location on the display. The weapon and the optical sight is now calibrated at the chosen range.
