Definitions
- the invention relates to a sighting device for a rifle with a rifle stock forming a shoulder rest and with a rifle stock associated with a target marking in the field of view having optics.
- the invention is therefore based on the object to design a sight for a rifle of the type described so that the uncontrollable relocations of the rifle can be at least partially avoided by hand due to its guidance.
- the invention solves this problem in that the rifle stock is adjustable relative to the shoulder rest with the help of actuators in two transverse axes and in that a periodically interrogated digital image capture device for a target area containing the target image and to the optics Image acquisition device, on the one hand, a memory for the digitally recorded image points and, on the other hand, an evaluation stage are connected, which actuates the actuators as a function of a possible shift of the image points queried by the image acquisition device compared to the image points read out from the memory of a previous query in the sense of a return of the image point shift.
- the displacements are adjusted as a function of these displacements, for the detection of which the optics are adjusted to a periodically pollable, digital one Image capture device for an image section containing the target marking is connected.
- This image capture device the resolution of which is comparatively rough can, because it is only a question of determining pixel displacements, is connected to an evaluation stage which compares the pixels obtained when the image capturing device is queried with the pixels of a preceding query which were stored in a corresponding memory for this purpose.
- the image point displacements determined during the periodic interrogation of the image capture device depend not only on body movements which cannot be influenced, but also on the respective guidance of the rifle, for example when tracking a moving target, it may be advantageous to evaluate the image point displacements as a function of the rifle guide or other parameters in order to enable a displacement of the rifle stock relative to the shoulder rest which is advantageously adapted to the respective conditions.
- the evaluation stage can be assigned a program memory for evaluation programs which can optionally be called up with the aid of an input device, so that the required adaptation can be carried out simply by selecting the respective evaluation program.
- the input device can be designed differently.
- the subject matter of the invention is shown for example, namely a sight device according to the invention for a rifle is shown in a simplified block diagram.
- the barrel 1 In the case of a rifle, the barrel 1 must be aligned with the rifle stock 2 with respect to a target which is supported on a shoulder rest 3 and this shoulder rest 3 is adjustably supported relative to one another along a horizontal axis 4 and a vertical axis 5.
- actuators 6 and 7 To adjust the barrel 1 about the axes 4 and 5 extending transversely to the barrel 1, actuators 6 and 7 are used, which are controlled via an evaluation stage 9 assigned to the sighting device 8.
- the sighting device 8 consists of an optic 10 formed by a sighting telescope, in the beam path 11 of which two mirrors 12 and 13 are switched on.
- the mirror 12 is semitransparent, so that some of the light beams are not fed to the eyepiece 14, but rather to a digital image capture device 15 which, on the one hand, inputs the image points digitally recorded with a comparatively coarse resolution together with a target marking into a memory 16 and on the other hand Evaluation level 9 provides.
- the image capturing device 15 is periodically queried via the evaluation stage 9, with the evaluation stage 9 having the digitally acquired pixels of the respective query and a preceding query via the memory 16 available for calculation.
- a possible shift can be determined from a comparison of the positions of these pixels and can be used for actuation of the actuators 6 and 7 in order to reverse the detected shift by counter-movement of the barrel 1 relative to the shoulder rest 3. With this measure, body movements that cannot be influenced and which are transmitted directly to the shoulder rest 3 and to the rifle stock 2 can be compensated for by a counter-movement of the barrel 1, the rifle being pivoted via the hand support as a pivot bearing.
- corresponding evaluation programs can be stored in the program memory 17 for the evaluation stage 9 and can be selected via an input device 18.
- a display for the retrievable and the respectively selected evaluation program can be provided in the field of view of the eyepiece 14, so that the shooter is provided with all the information necessary for the operation of the sighting device 8 via the eyepiece 14.
- the evaluation stage 9 can also be used to only allow the triggering of a shot if the displacement of the pixels meets certain conditions.
- the actuating switch 19 formed by the trigger can be blocked for this purpose via the evaluation stage 9 if the target conditions are not met.
