Definitions

  • the invention relates to a method for controlling and influencing running image sequences or individual images and interactive video scenes and / or image sequences below the reaction time perceivable by the human eye (real time), preferably in a simulator or shooting range, and a device for performing the method.
  • the police and military shooting training usually takes place in a shooting range with protective walls, with a target in the form of a target or a standing picture being set up at the end of a shooting range. After each individual shot or a series of shots, the evaluation and notification of the number of hits or misses takes place. With such a device, practically only the handling of the weapon can be practiced, while the actual target practice in response to the object is far from practice, in particular police practice.
  • the invention has for its object to provide means by means of which the running scene reacts to the action of the shooter in a period of time which is the natural Response time and the absorption capacity of the human eye corresponds.
  • This object is achieved according to the method according to the invention in that the images, image sequences or video scenes are influenced optically and / or mechanically and the signals caused thereby are recorded and in real time using a computer with data compression hardware and software according to known JPEG - (Joint Photographik Expert Group) and MPEG-Motion Picture Expert Group) are used to trigger new or changed images, image sequences or video scenes, whereby a hard disk memory (HDD) serves as a playback and recording device.
  • JPEG - Joint Photographik Expert Group
  • MPEG-Motion Picture Expert Group MPEG-Motion Picture Expert Group
  • an image sequence or video scene is played back as a primary main film from an external video source, video recorder or video disc player, and secondary alternative scenes are triggered by the light-optical and / or mechanical signals via the JPEG or MPEG method from the hard disk of the computer or PC computer imported using a video switch and a drive control interface.
  • the accumulating scene is only changed in real time on the basis of the reaction of the shooter in accordance with his hits or missed hits, the scene which is now automatically recorded being prepared and recorded as a "reaction scene", so that the impression of a real reaction is created.
  • the primary main film is played with the aid of a CD-ROM player via the digital data of the CD-ROM as a playback / recording device which, if necessary, is mixed and played with the secondary reaction scenes stored on the fixed memory or hard disk memory.
  • a laser disc player LVP / LD can also be used as a playback or recording device according to the invention.
  • At least one apparatus designed as a handgun is used as a means for optically or mechanically influencing an image, an image sequence or a video scene, which is designed to be loadable with the appropriate ammunition, each handgun having a sensor for registering a fired shot which detects the shot Signals transmitted by means of a transmitter built into the handgun or an electrical connecting line to a receiver which is connected to the input of the computer.
  • a sensor for registering a fired shot which detects the shot Signals transmitted by means of a transmitter built into the handgun or an electrical connecting line to a receiver which is connected to the input of the computer.
  • each handgun can be designed as a laser device for emitting laser flashes and can have a sensor for registering and signaling the transmitted light flash to the input of the computer.
  • the simultaneous use of multiple shooters can be used not only when using laser flashes, but also when using conventional ballistic projectiles.
  • the images, image sequences or video scenes are advantageously displayed on a reflection surface, and the signals caused by their light-optical and / or mechanical influence by the handguns are recorded by means of a video camera and the digital signals are fed to the computer for evaluation.
  • the headlight behind it, so that the bullet hole is visible as a light spot and can be recorded by the video camera.
  • the light spot can also be displayed in color.
  • the video camera can also be designed as an infrared camera and the reflection surface can be irradiated with infrared light from the front in an invisible manner.
  • an interactive video system plays a scene via the video projector on the screen (G) via a video switch (A).
  • a laser can be used instead of the real shot, which projects a light spot directly, which is equivalent to the light of the backlit shot hole.
  • the recording camera (E) now recognizes this light spot and emits the video information to a horizontal / vertical separator (F), which feeds this information to the computer (D).
  • the computer (D) which can also be designed as a PC, now compares the supplied horizontal / vertical information with the mask programmed for the image number and determines whether the rows and columns of the computer mask which are assigned to the corresponding images on the hard disk memory (HDD) are with the horizontal / vertical position or the coordinates of the shot hole or the laser light spot. A match is scored as a hit, a mismatch as a miss.
  • the computer (D) controls the video recorder (VR3) via the drive interface (B) and simultaneously switches its video signal through in video switching mode.
  • the drive control (B) was already in the pause position and was put on hold via the software shortly before the decision sequence was reached.
  • the video recorder (VR3) now continues the projection with the hit scene, for example in the one prepared Scene is played where the target object falls over. During this time, the video recorder (VR2) is already fast forward to the beginning of the next scene in order to wait for the switch back (VR3) to (VR2) in the pause position.
  • the video recorder (VR2) is now switched to the video recorder (VR1), which thus plays back the scene of a hit, for example the target object shoots back.
  • the system switches back to the video recorder (VR2) already in the pause position, which then continues the projection.
  • This method can be expanded using a larger number of video recorders and the scenes can be designed accordingly.
  • video images or video films are digitally broken down and loaded in "real time” (25 images / sec) by compression hardware or a computer plug-in card onto the hard disk.
  • the software installed in the computer or already installed controls the overall process, which proceeds as follows: When the start button is pressed, the film previously input via the computer runs through the decompression hardware and a VGA / TV converter via the video projector. The video projector projects the film onto the screen in front of which the shooter is standing.
  • the shooter now shoots at the target object appearing on the screen, the projectile penetrates the screen and releases the back light at the shot hole, generated by headlights H.
  • the shot recording camera (C1) now recognizes the light spot, which can optionally also be generated by a laser device, which generates a similar light spot, and supplies this information to the camera A / D converter.
  • the position of the light spot is broken down into horizontal lines and vertical columns.
  • This information is then compared to the pixel grid of the screen holder and the corresponding pixels are determined. These pixels are now compared with the pixels of the hit mask belonging to the image and, if they match, are evaluated as hits.
  • the hit mask is a number of pixels which correspond in position and position to the target object of a video image and which are directly assigned to the respective video image.
  • All other pixels that are outside the hit mask are counted as non-hits if they match the light spot pixels.
  • the shooter hits the target object on the screen, the shot camera recognizes the light spot and passes the columns and line data on to the mask comparison software. This now decides whether the light spot matches the pre-programmed pixels for hits.
  • the scene "hit” is now played on the screen, for example the target object collapses, which was passed on from the hard disk to the video projector via the decompression hardware.
  • the track / track search time is only approx. 5 ms and can be reduced to 0.3 ms when using a cache controller, but 20 ms are available for a field, the picture / scene jump is not visible to the human eye, and it gives the impression that the film or the projection has reacted directly to the shooter's intervention.
  • This function is defined as an interactive function.
  • the function sequence is generally identical to the function sequence "hit", except for the reaction of the mask comparison software, which now addresses and calls up the scene "no hit".
  • the scene hit is played via the decompression hardware and the video projector.
  • the image access time is in the range of 5 ms or 0.3 ms when using a cache control, the image / scene jump is again not visible to the human eye, and the effect already described under the "hit" function occurs.
  • the hard disk plays the film continuously via the decompression hardware, and the target object behaves passively, since only when the shooter reacts by activating the shot-recording camera, hits / no-hits are jumped into the corresponding reaction scenes.
  • FIG. 2 shows a schematic representation of the device with two handguns W1 and Wn, a PC computer PC and a projection screen Z in a functional connection.
  • the circuit corresponds to the representation according to FIG. 1.
  • the designation Wn for the second handgun indicates that the number of handguns can be significantly higher.
  • Every handgun is equipped with a sensor, which registers the time of the shot and feeds the resulting signal to a transmitter which forwards the signal to the receiver R.
  • the signal can also be routed to the computer via an electrical line.
  • the signals caused by the handguns W1 and Wn and recorded by the sensors S1 and Sn are fed to the computer PC, which immediately receives the signals from the video camera C1 via the shot results, which are evaluated in the computer and which then controls the scenes that are triggered from the hit evaluation, as described above.
  • FIG. 3 shows a schematic representation of the device with two handguns W1, Wn, a PC computer PC and a still picture T as a simplified embodiment of the invention.
  • the handguns can be equipped as ballistic weapons or with a laser device. Their number can be considerably larger than two.
  • the still picture T can be equipped with sensors which react to mechanical shocks, namely when a projectile has hit the still picture.
  • sensors For the reception and localization of laser flashes on the still image, a number of sensors can be arranged, each of which detects a specific area on the image, so that the hit quality can also be determined and fed to the computer PC, which reacts to the still image triggers.
