Description

The The present invention relates to an automatic shooting range Hit evaluation and a method for carrying out an automatic hit evaluation.

conventional shooting usually consist of several shooting ranges, in which a variety of shots on one or more shooting targets or other target objects are given. With conventional processes to operate such shooting ranges will be at every shooting range after one or possibly several shots a hit evaluation, e.g. with the help of an electro-optical scanning device, and the shooter over one Screen displayed at the respective shooting range. This allows every shooter one individual control of his shooting performance.

Such a shooting range is from, for example DE 295 12 828 U1 known. Shots are fired at conventional targets, which are moved into the shot position in the form of an endless paper belt via an automatic transport device.

Also the DE 41 13 677 A1 describes a shooting range in which bombarded shooting targets from a target stock are mechanically transported to a shooting position and evaluated immediately after bombardment with an optical scanning device.

Furthermore concerns the DE 195 07 121 A1 a disc towing system, in which a disc carriage is dragged back and forth on two fixed carrying ropes, with the aim being a particularly optimal positioning of the disc. Such a target is intended for a shooting range for training or shooting in for shooters, hunters and gunsmiths. Such a shooting range is less suitable for a competitive operation, since the shooter is usually able to exert direct influence on the shooting target, because after the bombardment the target is brought up to the shooter.

The DE 42 07 933 A1 relates to an arrangement for electronic evaluation of the video image of a bombarded shooting target; the disk is shown on a monitor; a monitor determines the number of rings. The traditional evaluation of shooting targets or target mirrors ("Blatt1") by means of a dowel and a partial target can be dispensed with, in which mistakes due to ineptitude or taking sides were inevitable.

The DE 41 13 677 A1 describes a method and an apparatus for automatic hit display; a conventional shooting target is brought into a firing position from a target magazine, fired at and then illuminated from behind so that the shots illuminated from the front can then be scanned by a video system which displays the hits on a monitor. Then the shot target is put down and replaced with a new one.

The DE 38 06 644 C2 describes a disc system with a continuous belt, on which complete shooting targets are successively printed, each of which is assigned centering means for the precise alignment of the respective shooting target relative to a photoelectric scanning device.

The DE 295 12 828 U1 describes a target system with a continuous belt on which complete target targets are printed. The hits are recorded electro-optically, the evaluation via a computer system, which combines several shooting ranges.

A The object of the invention is the shooting ranges described above Kind of a simpler and more reliable To ensure hit evaluation.

The Invention achieves this aim by the subject matter of claims 1 and 10. Further advantageous refinements for this are described in the respective dependent claims.

After that the invention creates a shooting range with automatic hit evaluation, with: a transport device for transporting a target tape in a shot position; an aperture with one of the desired Target mirror corresponding aperture opening, in the shot direction is arranged in front of the target band and an evaluation device, at which the target band is shot past. In a method according to the invention for automatic target evaluation in a shooting range becomes a target field an aperture in front of the target tape with a desired one Window mirror corresponding aperture opening and the shot Target tape scanned and the scanned image for further use processed electronically.

Preferably a light aperture is arranged in front of a dark target band so so that from the Gunner's point of view a conventional target appears in the target field.

On This largely prevents manipulation of the target object. When using conventional targets, different ones can be used Targets are prepared differently. At the shooting range according to the invention provided that a and the same aperture is used several times so that the disc mirror at least for a series of shots the same remains.

Further Consumables are made up of the aperture and the target band together. With conventional Shooting ranges exist the consumables from the targets. An exact hit determination is with conventional Targets only possible if one per shot Target is used. This results in considerable cost burdens for continuous operation. At the shooting range at hand, only the target range is "used up"; the aperture will however, only accidentally hit and damaged. she must therefore are rarely replaced. The target band depends on the request transported by the user. The user therefore has one direct influence on target tape and aperture consumption.

alternative to a fixed aperture, the aperture can be used as an aperture band with a or more apertures be equipped, with the aperture band device via a Transportvorrich in the firing position is closed and retractable. The transport device is preferably with one - with the control of the evaluation device coupled - electronic Scanning device equipped to pass the aperture band is to determine the exact position of the aperture.

Also can be the one you want Aperture with Help one nearby of the aperture band arranged tool, preferably punching tool, are generated, the aperture also that directly target band behind penetrates. By scanning the opening in the The position of the aperture in the aperture band can also be determined.

For different Shooting disciplines, e.g. running boar, duel shooting, etc., it is advantageous to add another object tape - in the weft direction seen - before the aperture arranged, the object belt via a transport device in the firing position or removable and preferably on one, with the control of Evaluation device coupled - electronic scanning device is passable. The object tape contains one or more cutouts, which the outline of the desired target objects, e.g. an animal shape, and the target objects on the behind the aperture area depict. Through a synchronous and / or relative movement of object and aperture band can be on simple way different processes in the target area for the shooter can be simulated.

The tool 231 is over a line 250 with the line 153 connected. The tool exchanges via the line 250 Data with the evaluation 140 out.

An arrow 161 marks the direction of flight of the projectiles to the target area 234 ,

For further shooting disciplines can the system with a third film, so-called object film or object tape, equipped become.

A film 262 , so-called object belt, is made by a cylinder 261 unwound and to a cylinder 260 led, on which it is wound. Between the two cylinders 260 and 261 are a fixation 264 and a pair of roles 263 ,

The film 262 is provided with openings that can give the shooter a view of the actual target area and block it again. Can also on the film 262 , together with the above openings or independently, a motif as a target. Will the film 262 moved, a moving target can be formed. The film can also 262 be designed as a projection surface and the motif can be projected.

The target area 234 can be carried out so that multiple targets are visible from the shooter's point of view. This is required for the shooting disciplines "running boar" and "duel".

Inaccuracy in the side guidance of the film 202 can with a location scanner 215 recognized and taken into account in the calculation of the hit position. The fixation 204 can watch the movie 202 additionally lock until transport. This will shift the film 202 prevented during penetration of the projectile.

Instead of the fixed hit scanner 214 can also be a movable flatbed scanner 233 the hit evaluation in the target area 234 carry out. An additional printer can mark the individual hits after the evaluation.

The 2 shows a section of the target film from the front. The film 300 can have a perforation 301 exhibit. It can either be on one side or on both sides. The perforation 301 can also be omitted. To simplify the illustration, white was chosen as the film color. In the real product, a film color must be selected in accordance with the rules of the UIT for the dark part of the targets.

The film 300 can be a continuous marker 302 exhibit. The mark 302 can either be on one side or on both sides. The mark 302 can also be omitted. The mark 302 is to be attached so that it is not in the shooting range of the shooter and from the hit scanner 214 can be detected.

Will the film 300 pierced by a projectile, there is a hole at the penetration point 303 ,

In a further embodiment variant, the rings of the targets can also be used on the film according to the rules of the UIT 300 be shown.

The 3 shows the most important functional elements of the target field from the perspective of the shooter. The housing is not shown.

The cylinder 200 wraps the film 202 on. The cylinder 201 rolls the film 202 from. The hit scanner 241 gropes the film 202 from.

The target area 234 is through the bezel 222 optically limited to the dimensions of the desired lens size. In the aperture 222 there is an opening that gives the view of the film 202 releases. The shooter sees an image from the shooting position that corresponds to the image of a conventional target.

The following advantageous effects can be achieved with the overall system proposed here:
A target with rings and target play gel does not have to be used as the target. In all cases, the shooter only sees a dark point from the shooting distance, which is surrounded by a bright area. The automatic shooting range represents the shooting target composed of two elements. From the shooter's point of view, there is no difference to a conventional target.

Has the shooter a shot the target area submitted, the hit evaluation starts automatically. after the The hit position was determined, the evaluation gives the hit data to a computer. This represents the hit in a 'Sagittarius' media center the hit is also shown there. If a log printer is available, the data of the hit are logged there. Are further system computers connected to a local network, the data is sent to the the connected result calculator.

is also an administrative computer a WAN connected, the hit data from the result calculator transferred to the management computer. The administration computer coordinates the competition. On the administration computer the media adapter is connected. This gives the competition data to the media institutions. The competition dates consist of the Shooting results and the pictures of the shooters and shooting ranges taken as well as the audience.

The Construction according to the invention of the shooting range make sure that shooting range can be evaluated automatically and the evaluation result can be checked at any time by manual intervention. In addition is the shooting range so constructed that a minimal consumption of targets occurs.

The Combination of automatic scanning of the result with a virtual target from a light aperture and a dark target film. The aperture is placed in front of the target film so that it is visible of the shooter a conventional target appears.

The The cover can either be fixed or as a film or tape. The target film is led behind the aperture. He is between two roles clamped. The roll for winding up the used film becomes powered by a motor. The role with the bombarded Film is either by a spring or by another motor so driven that the Target film is subjected to a constant voltage.

Becomes the aperture is also formed by a film, so on the Cylinder on which the unused screen material is wound is, by a constant torque against the unwinder applied.

Becomes the target film as a projection surface executed the cover can be omitted. The target is projected onto the target film. If the projector is precisely adjusted to the target surface, the Evaluation as described above. Alternatively, the evaluation also take place behind the target film using a movable scanner. If the target film is translucent, the scanner can view the projected image the target and hit.

As Target film is a material to be used, which is preferably under true to size in all operating conditions is. When evaluating hits, a scanner is used to determine the position either a perforation or a mark on the target film used. Finds a bullet hole in the film, its position is relative to the location of the perforation or determined relative to the location of the mark. Since the absolute location of the Film at the time the project file hits the film is known, the absolute hit position can be determined exactly.

The shooting range according to the invention is suitable for the following disciplines:
In the "fixed target", the shooter fires one or more shots at a target, which remains at rest during sighting and firing. This is the simplest mode of operation Shooting range. To replicate a target, a moveable film is sufficient, which the projectiles penetrate and whose penetration points are then measured.

In "duel shooting" the shooter fires shots one or more targets that are only visible to the shooter for a short time are. shooters use conventional targets Targets, police and military Often also use targets that outline the outlines of people symbolize.

The The goal is often achieved by folding away or by turning away from the field of vision of the shooter taken. The goals are always visible in the same place.

Difficult is in duel shooting the evaluation of the shot targets. So far the disks either manually removed from the target body and subsequently evaluated with different methods. Through manual collection the target is the shooting range for the firing operation locked for a relatively long time. With automatic collection, the Complete mechanics to cover the target from the target area to the Place of firing transported. There the user removes the disc and evaluates it this out.

The shooting range described here allows the fully automatic operation of the target with subsequent automatic Hit evaluation.

by virtue of which mostly offer horizontally adjacent targets there is a rotation of the shooting range to the horizontal. The aperture is designed so that no longer just a goal, but the desired number, usually five, target fields can be displayed side by side. A third film with accordingly greater Recess optionally gives a view of the actual target and then blocks the view again.

The target film 202 becomes a hit scanner after the fire 214 driven and evaluated there for all goals.

To ensure that the shooter did not shoot during a time when the aperture was in front of the target field, the aperture can 262 can also be scanned by a scanner. Is the aperture 262 If a projectile has also penetrated the target field, the hits are not counted.

In another embodiment, the shooting ranges can only be provided for one target area at a time. In the aperture film 262 then there is only one opening for a target area. The aperture film 262 becomes dependent on commands from the higher-level result calculator 126 drove in front of the target area and drove away again. In order to be able to display several targets at the same time, a corresponding number of shooting ranges are set up next to each other, which receive the commands to release and lock the target field at the same time.

through of the shooting range presented here for the shooting operation significant improvements. By eliminating the need to collect discs becomes the shooting operation not unnecessary interrupted for a long time. The expensive shooting range is better utilized.

Instead of the film 262 a conventional flap can also be used to cover the target.

In the shooting discipline "running boar" moves in Target with the appearance of an animal through the target field. The Sagittarius has a limited time to fire.

This can be achieved with the shooting range described here in that the outline of the animal as an opening in the aperture film 222 is incorporated and the aperture film 222 is moved at the desired speed. The target film 202 is not moved during this time. In addition, in the film 262 there should be an opening that provides a view of the target. Damage in the film 262 can be recognized and serve as an indication of a miss.

The impact detector 213 reports the impact of a projectile and the time of the impact. It is thus possible to determine exactly where and at what time the outline of the animal is in the film 222 has found. In the subsequent hit evaluation of the film 202 can accurately hit relative to the motion of the film 222 be determined.

Finally, the shooting range can be operated in different modes. Depending on the operating mode used, the consumption of the target film is different:
In one operating mode, the target film is transported after the shot has been fired and evaluated so that the transport path corresponds to the target height of the desired shooting discipline. This mode ensures that only one hit can be found in an area on the film. The manual hit evaluation is always clear in this operating mode.

In another operating mode, after the shot has been fired and evaluated, the target film is transported back so far that the shot hole is no longer in the target field. In this mode the hit assignment can only be done manually by comparing all previous hits with the associated transport routes. The order of the hits on the film corresponds to the order in which the shot was fired. Manual hit evaluation is always clear in this operating mode as long as the target area used is surrounded by a bulletproof frame. If a shooting range for larger targets is used for a shooting discipline with smaller targets, this is not always guaranteed. The consumption of film material depends on the shooting results. Overall, it is lower than with the previous operating mode.

In Another mode of operation is the target film after the shot has been fired and transported back as far as the evaluation, that itself the shot hole is no longer in the target area's mirror. In This operating mode can only be compared by comparing all of the previous ones Hits with the corresponding ones Hit routes are carried out manually. Are located hits in the aperture within the target field but outside of the disk mirror, is not a clear manual hit evaluation more is possible. The consumption of film material depends on the shooting results. Overall, it is lower than with the previous operating modes.

In Another mode of operation is the target film after the shot has been fired and the evaluation just as far as the operator is specified. Manual hit evaluation is only possible if the transport route is long enough possible. The consumption of film material corresponds to the setting.

In one of the above variant the aperture is replaced by a second film, the so-called aperture film, educated.

Optional the aperture film is also made with markings and the opening Provide release of the view of the target film. So that with one Scanner the relative position of the aperture to the target film can be determined.

Optional the aperture film is provided without markings and without openings. After every Transport is locked out of the aperture film in its target position. Then the aperture film and the target film are cut in with a punch opening in one operation Die-cut on the target film for viewing.

Then will the location of this opening in the Measure the target film. This means that the assignment of aperture film to target film can be made exactly be determined.

In a further embodiment becomes the target area continuously monitored by the camera. The supervision the target area can be used for two purposes. By comparison with previous ones The impact of a projectile can be recognized in images. In order to the hit evaluation can be started.

through the visual target area detection can hit evaluation can be started according to various criteria. In the simplest case, the evaluation is started after every hit. In the most complicated case, the hit evaluation is only started when if the impact of another project file is not a reliable evaluation would result in more.

There the camera the target area continuously recorded can be determined after each hit, whether a new hit with the same caliber a hole pattern would arise, which can either lead to ambiguous evaluation results or in the target film so big free fields arise that a Projectile can penetrate without causing a change in the target film.

Become two target films with a defined distance and the corresponding evaluation used, can be determined based on the offset between the hits whether the shot from provided place was given.
