Strijelac ručnim oružjem za vrijeme kretanja nije u mogućnosti kontinuirano zadržavati pažnju na meti i točki pogotka. Za precizno ciljanje strijelac se mora nakratko zaustaviti, fokusirati se na metu te poravnati prednji i stražnji ciljnik s metom, što u pravilu znači gubitak dragocjenog vremena. U uvjetima jakog svijetla ne pomaže ni laser ugrađen na oružje jer je laserska točka teško uočljiva. Problem je riješen sustavom za ciljanje ručnim oružjem primjenom proširene stvarnosti. Sustav koristi naočale (1) s ugrađenim kamerama (3) i računalom (4). Računalnom obradom slike s kamera (3) otkriva se točka pogotka. Pred okom strijelca se na prozirnim zaslonima (5) iscrtava končanica (12) koja označava točku pogotka (16). Končanica se na prozirnom zaslonu (5) naočala (1) iscrtava kontinuirano, sve dok je oružje usmjereno u smjeru gledanja, bez obzira na ostale aktivnosti strijelca. U trenutku kada se strijelac odluči na hitac končanica označava točku pogotka te je moguće brzo i intuitivno ciljanje bez potrebe podizanja oružja u visinu očiju i gledanja kroz ciljničke sprave. Sustav se primjenjuje na ručno oružje (6) s ugrađenim laserom (7) i ručno oružje (10) s ugrađenom kamerom (11). Kod ručnog oružja s ugrađenim laserom (7) točka pogotka, označena laserskom točkom (9), otkriva se obradom slike s kamera (3) na naočalama (1). Kod ručnog oružja s ugrađenom kamerom točka pogotka otkriva se usporedbom slika s kamere (11) na ručnom oružju (10) i kamera (3) na naočalama (1). A handgun shooter while in motion is unable to hold attention to the target and the point of impact continuously. In order to target more precisely, the shooter needs to stop for a moment, focus on the target and align the front and rear sights with the target, which normally means wasting valuable time. In bright light conditions, not even a built-in laser is of any help, since the laser point is hard to detect. This problem is solved by the augmented reality based handguns targeting system. The system utilises glasses (1) with built-in cameras (3) and a computer (4). Computer processing of the image obtained by cameras (3) discovers the point of impact. Before the shooter's eye, the reticle (12) is outlined on the transparent screen (5), marking the point of impact (16). The reticle on transparent screen (5) of glasses (1) is maintained continuously, as long as the weapon is directed in the watching direction, regardless of the shooter's other activities. The moment the shooter decides to shoot, the reticle marks the point of impact, enabling fast and intuitive shooting, requiring no repositioning of the weapon to the eye level and looking through the targeting devices. The system is used for handguns (6) equipped with a laser (7) and handguns (10) equipped with a camera (11). In handguns with built-in laser (7), the point of impact, marked with laser point (9), is detected by processing the image from cameras (3) on glasses (1). In handguns with built-in camera, the point of impact is detected by comparing images from camera (11) on the handgun (10) and cameras (3) on glasses (1).
