PCT No. PCT/SE96/01757 Sec. 371 Date Aug. 12, 1998 Sec. 102(e) Date Aug. 12, 1998 PCT Filed Dec. 27, 1996 PCT Pub. No. WO97/25583 PCT Pub. Date Jul. 17, 1997An impact position marker for ordinary or simulated shooting from a fire-arm (1) towards a moving target comprises a sensor part (2) with an evaluation unit for the actual position of the target in relation to the fire-arm and a firing detector. The evaluation unit comprises an image taking device (10) with its optical axis directed in parallel with the sighting line of the fire-arm (1), a unit (11) which measures the rotation of the sighting line of the image taking device in at least two planes at an angle to each other and comprises one and the same line coinciding or parallel with the sighting line of the fire-arm. The output signals from the image taking device (10), the rotation-measuring unit (11) and the firing detector (12) are inputted to an evaluation unit (13) which calculates the distance to the target and the position of the point of impact in relation to the target at the calculated impact moment. The result of the measuring is presented on a presentation unit (4) and/or controls an acoustic feed-back signal which assists the shooter during aiming and firing. |
