Definitions

  • the subject of the invention is a mobile training shooting target that allows detection of bullet hits and a method of detecting a hit on a training shooting target, consisting in the identification of the point where the bullet hit changes the visual state of the target.
  • hit detection consists in detecting electrical impulses resulting from the penetration of a metal bullet, by means of numerous sensors located in the "body" of the mannequin.
  • sensors those in critical locations for the life of the human, as symbolised by the mannequin, are separated in terms of signalling. Thanks to this, in addition to hit detection itself, additional verification is performed whether the hit was in a critical spot.
  • EP3504506B1 discloses a similar shooting target with a mannequin on a drive chassis, equipped with multiple pressure sensors, which register a local increase in pressure caused by a bullet.
  • Publication No. EP3504506B1 discloses a similar shooting target with a mannequin on a drive chassis, equipped with multiple pressure sensors, which register a local increase in pressure caused by a bullet.
  • US2017/370683 discloses a stand intended for dynamic sport shooting by many competitors at one paper target, which does not require close-range observation of a punctured target for assessment of the shooter's accuracy before a subsequent competitor is allowed to shoot.
  • a traditional paper target is placed in a metal frame and observed at close range, but out of the line of fire, by a vision camera with an image analysis system.
  • the aforementioned system records, on an ongoing basis, local visible spectrum reflectivity changes caused by the penetration of the paper target by a bullet.
  • the image analysis system needs to ensure recognition and rejection of changes in reflectivity resulting from target vibrations, including strong vibrations caused by the bullet hitting the aforementioned metal frame and changes in illumination intensity of the target resulting from available light.
  • the publication PL227256B1 discloses a method of detecting bullet impacts on a target using an external thermal imaging camera and a thermal image analysis system for the hit target.
  • the hit detection procedure consists in comparing the thermal image of the target before shooting with the live image, in which the spots with a point temperature increase of the target surface by a set value are distinguished.
  • the goal of the invention is to improve shooting training effectiveness.
  • the goal is implemented by a mobile training shooting target with a drive chassis, a mannequin mounted on this chassis, means of detecting a bullet hitting the mannequin, means of recognising a hit in a critical area of the mannequin and means of visual signalling a hit of the mannequin.
  • the invention consists in that the mannequin has a form of a thin-wall rigid curvilinear dome shell with an open base facing the drive chassis.
  • the mannequin shell has a part closer to the chassis of the target, symbolising the torso, and a part farther away from the chassis, symbolising the head.
  • Inner surface of the said shell is generally smooth and a has an uniform colour, advantageously black.
  • Bullet hit detection means and hit area recognition means consist of an image analysis system with an image sensor and an illuminator, working in the infrared spectrum. The image sensor lens and illuminator are located at the base of the mannequin and directed at its interior.
  • the base of the mannequin shell has an elliptical outline
  • the image sensor lens is located substantially centrally at the said base
  • the illuminator consists in an array of light emitting diodes surrounding the lens.
  • the illuminator comprises luminescent diodes for the target emitting electromagnetic radiation with a 940 nm wavelength and the image sensor lens is corrected for distortion and equipped with a 940-960 nm bandpass filter.
  • the mannequin is made from paper pulp, for example of two vertical paper extrusions glued together, with a thickness between 2 and 4 mm.
  • the visual means for signalling impact on the mannequin consist in a mechanism tilting the said mannequin in relation to the drive chassis.
  • the above-mentioned target also implements a method according to the invention, in which locations are identified, where the hitting bullet changes the optical properties of the target.
  • the invention consists in that as the target a mannequin in the form of a thin-wall rigid curvilinear dome shell with an open base is used. Inner surface of the said shell is generally smooth and has an uniform colour, advantegously black.
  • an infrared image sensor lens is placed and connected to the image analysis system, and also assures uniform infrared illumination of the mannequin inner surface.
  • the image analysis system registers on an ongoing basis the view of the inner surface of the mannequin reduced to its projection on the plane, and sudden and essentially point changes to this image and the time of the said changes are identified in the recorded image.
  • a mannequin whose shell has a part closer to the chassis, symbolising the torso, and a part farther away from the chassis, symbolising the head.
  • a hit is identified based on an analysis of an image constituting a projection of the inner surface of the mannequin onto an ellipse.
  • a mannequin made of paper pulp which can be made of two vertical paper extrusions glued together with a thickness between 2 and 4 mm.
  • the invention facilitates shooting training held for officers, soldiers and competitors in dynamic shooting competition by improving exercise realism while maintaining an appropriate level of safety. It assures easy implementation of various training scenarios imitating actual combat conditions.
  • a human-like mannequin can be dressed accordingly to the type of training, increasing its realism without affecting the system's accuracy.
  • the invention facilitates quick assessment of shot accuracy by clearly indicating the hit location, and in many cases also the direction from which the shot was fired, which is of particular importance especially in a situation where several shooters are firing at the same target from different locations.
  • the invention also allows for the use of inexpensive and environmentally friendly paper mannequins, with relatively high wear resistance, as they can withstand at least two hundred hits with only slight deterioration in the detection of subsequent shot holes.
  • the thin-walled mannequin is light, so it does not significantly raise the centre of gravity of the chassis, which is particularly important when the target moves in more difficult terrain conditions.
  • Fig.1 is an axonometric front view of the mobile target according to the invention
  • Fig.2 is a side view of the target
  • Fig.3 is a front view of the mobile target mannequin
  • Fig.4 is a front view of the system detecting two bullet holes through the mannequin of Fig.3
  • Fig.5 is a side view of the same system.
  • Fig.6 shows the projections of the shot holes from Fig.4 and Fig.5 on the plane of the base of the mannequin and the method to identify the location of both holes
  • Fig.7 shows an embodiment of a mannequin interior illuminator, shown schemnatically in Fig. 4 and Fig.5 .
  • the examplary mobile target has a drive chassis 1 with four wheels 2, as known from other mobile robots.
  • a rigid paper humanoid mannequin 3 is placed, made of 2 to 4 mm thick paper pulp and glued together from two symmetrical vertical halves 3' and 3".
  • the mannequin 3 has the form of a rigid curvilinear domed shell with an elliptical open base 4 featuring two visually distinct parts.
  • the part of the shell closer to the chassis 1 symbolises the torso 5 and is topped with a part symbolising the head 6, with part 5 smoothly transitioning into part 6.
  • the sizes of parts 5 and 6 of the mannequin 3 correspond to the average size of the human body parts they symbolise.
  • the elliptical base 4 of the mannequin 3 fits in a rectangle with dimensions 450 x 300 mm, while the overall height of the mannequin 3 is between 750 and 800 mm.
  • the inner surface of the mannequin 3 is generally smooth and covered with matte black paint. It is essential for the inner surface of the mannequin 3 to be fully visible from the centre of its base 4. This condition is met by a shell, in which each subsequent projection crofg a oss-section of its inner surface onto the plane of its base 4 along a plane parallel to this base, starting from the base 4 of the mannequin 3 towards its top, fits within the area of an analogous cross-section projection of the said surface along the previous plane.
  • the upper part of the chassis 1 features a system for detecting a bullet hit on the mannequin 3 and recognising the hit area of the mannequin. Detection of hits on the mannequin 3 is performed by an image analysis system with an image sensor with a resolution of 3000 x 2000 pixels, working in the infrared wavelength.
  • the lens 7 of the image sensor is located centrally, approx. 160 mm below the base 4 and pointed vertically towards the interior of the mannequin. 3.
  • the lens used has a 3 mm focus length, is corrected for distortion and equipped with a 940-960 nm bandpass filter.
  • An illuminator 8 of the inner surface of the mannequin 3 containing electroluminescent diodes (LEDs) 9 with a 940 nm wavelength, shining into the interior of the mannequin 3 is placed around the lens 7.
  • Fig. 7 shows rectangular LEDs 9', used for surface mounting, with different lighting angles, and classic LEDs for through-hole mounting 9", where a change of the light direction of the latter can be corrected easily and without tools. Thanks to this illuminator 8 solution, it is easy to obtain uniform infrared illumination of the entire inner surface of the mannequin.
  • the method used for detecting a hit on mannequin 3 is described below on the example of detection by the image analysis system of two holes made in the shell of the mannequin 3 by one bullet, i.e. entry hole P1 and exit hole P2.
  • the flight path of the bullet is indicated by a dashed line with an arrow in Fig.4, Fig.5 and Fig.6 .
  • the matte black inner surface of the mannequin is punctured, as observed by lens 7, the bullet hole rapidly and locally changes the ability of this surface to reflect radiation.
  • Such a change can be easily detected by the image analysis system, especially with the colour of the material used to make the mannequin 3 contrasting with the interior colour of its shell and this contrast becoming visible at the moment of bullet penetration.
  • the state of the inner surface of mannequin 3 is analysed in its projection onto the horizontal elliptical surface 10.
  • a grid of horizontal 11 and vertical 12 lines shown as broken lines in Fig.3
  • Fig.3 a grid of horizontal 11 and vertical 12 lines, shown as broken lines in Fig.3
  • Fig.3 a grid of horizontal 11 and vertical 12 lines, shown as broken lines in Fig.3
  • Fig.3 a grid of horizontal 11 and vertical 12 lines, shown as broken lines in Fig.3
  • Fig.3 a grid of horizontal 11 and vertical 12 lines, shown as broken lines in Fig.3
  • the elliptical surface 10 in the form of concentric ellipses 13 and straight line segments 14, extending from the geometric centre 15 of the elliptical surface 10.
  • the image analysis system also records the time of appearance of the P1 and P2 shot holes. If the time interval between the appearance of shot holes P1 and P2 is sufficiently small, in practice not longer than 3 ms, shot holes P1 and P2 are assumed to be caused by one bullet. In such a situation, the direction of the shot that caused the P1 and P2 shot holes in relation to the chassis 1 can also be determined. If both the mobile target and the shooter are equipped with a geographic positioning system, for example a GPS system, it is also possible to determine the location in the field from which the recorded shot was fired.
  • a geographic positioning system for example a GPS system
  • Projection of the inner surface of the mannequin 3 on the surface 10 allows for the identification of critical areas on this surface.
  • the "head" 6 projection is in the centre of the surface 10 and the detection of two consecutive shot holes with one bullet in this projection area can be interpreted as a fatal shot.
  • the results of the hit detection system can be analysed both post-factum, for example during a discussion of the training results of an entire shooting team, as well as in real time through observing hits on the display of a terminal connected wirelessly to the mobile target. Detected hits can also be signalled to shooters participating in the training. In the described example, this is done by changing the position of the mannequin 3 with respect to the chassis 1.
  • the mobile target stops and a mechanism, not shown in the drawing, tilts mannequin 3, after which it returns to vertical, and the mobile target continues moving.
  • a hit of a critical area can be signalled with a longer stop of the target and a deeper "tilt" of the mannequin than in the previous case 3.
