Description

The present invention relates to a view simulation device

pan using a

  optical device, such as a binocular telescope

  eyepiece, sight of a portable weapon, etc. According to DE-OS -26 58 501, it is known to place in front of the viewfinder of a cannon a television monitor on which is represented an image composed of an environment and a target While the trajectory of the target is established

  and can be predetermined by calculation, the pointer movement

  l Hostage of the weapon is coupled with the movement of a camera

  television, which receives a panoramic image representation.

  According to DE OS 29 19 047, it is also already known to perform a memorization

  digital panorama and display parts of this panora-

  ma on a television monitor according to a pointing movement of a weapon, in which case also moving targets

  can be cut out from the image shown.

  In these known devices, the TV monitor

  vision is arranged in the field of vision of an optical system which is operated by a pointer and which is equipped with address sensors which determine the part of the image to be represented

  from the panorama by the addresses provided.

  Combat tactics for soldiers using * firearms, including anti-tank weapons, however, require

  observation of the combat zone by the gunner or the

  tank principal using a binocular telescope so that, in the case of detection of a target, this fact can be indicated to the monitor Such a binocular telescope must however be freely and without limitation movable The same consideration s applies to a weapon carried by a pointer, such as an anti-tank weapon using the sight of which the target to be hit is aimed Until now, it has not been

  possible to realistically simulate such processes.

  The object of the invention is therefore to provide a device which allows the simulation of panoramic view in a realistic manner using an optical device. According to the present invention there is provided a device determining the direction of vision of the optical device, a television monitor placed in the path of the rays of the optical device and a control of the television monitor with image data stored in correspondence to the defined viewing direction. According to other particularities of the invention (a) the device determining the direction of vision comprises transmitters coupled with the movement of

  the optical device and a receiver placed in a fixed position.

  (b) the transmitters are arranged on the optical device. (c) the transmitters are placed on a helmet of a

  person handling the optical device.

  (d) the stored image data includes both a part of a panorama and the representation of at

minus a target.

  (e) an electronic breakdown of the

target in the panorama part.

  (f) in the case of a binocular telescope, a diopter is provided to conduct the two beams of radius

  right down to the TV monitor.

  Other advantages and characteristics of

  the invention will be highlighted in the following description

  tion, given by way of nonlimiting example, with reference to

  Refer to the accompanying drawings in which:

  FIG. 1 represents a device for simulating

  lation of panoramic view through a binocular telescope, FIG. 2 is a view of part of FIG. 1, the binocular telescope being used by an observer provided with a helmet, and

  FIG. 3 represents a device for simulating

  Pointer of panoramic view with deletion

  essential characteristics shown in fig 1.

  In accordance with FIG. 1, an observer 10 looks through a binocular telescope 12, the two vision channels of which emerge via a diopter 14 in front of a miniature television monitor 16 On the device consisting of the binocular telescope 12, the diopter 14 and the monitor 16, two transmitters 18 and 20 are provided, the

  signals are received by a receiver 22 placed in a position

  fixed position This receiver 22 determines the direction of vision of the optical device 12-16 The transmission / reception device 18-22 can, for example, be produced as is known from DE-OS 24 14 192 In apart from acoustic signals, as described in the invention, the transmission / reception device can also operate

  with optical or other electromagnetic signals -

ticks in an invisible area.

  Depending on the vision direction determined by the reception device 22, a vision simulator

  24 determines the image to be displayed on the television monitor

  sion 16 This image usually consists of a part

  of an electronic area and diaphragm targets-

  ment Such a vision simulator corresponds for example to the subject of the German patent application P 31 33 866 6 It comprises a digital memory of panoramic images 26 and a digital memory of targets 28 for one or more targets A processor 30 chooses , as a function of the established direction of vision, by means of an electronic access circuit 32, an image part from the

  panorama memorized in memory 26 and it combines coordinates

  data to the image portion from the target stored in memory 28 via an image synthesizer 34 The image synthesizer 34 can further decide whether the target should be represented behind or in front of individual objects located in the image part, such as houses, coppices, etc. After a digital / video conversion in a converter 36, the representation of the composite image is carried out on the monitor television 16 The observer 10 thus obtains, when he looks in the binocular telescope 12, as a function of his direction of vision, different image parts containing targets on the television monitor 16, in which case the effective vision of a real area of land

  with targets is simulated in a way very faithful to reality.

  In accordance with FIG. 2, the transmitters 18 and 20 can also be arranged on a helmet 44 that is worn

  the observer 10 who manipulates the optical device is composed

  health of the binocular telescope 12, the diopter 14 and the television monitor 16. In FIG. 3, an anti-tank weapon has been shown, which is launched from a launching frame The launching frame comprises a launching tube 38 on which is disposed on one side the television monitor 16 in place of the otherwise conventional viewfinder and which further comprises a position sensing unit 42, which comprises

  example three gyroscopes serving as angular speed sensors

  space in the three axes of space The signals provided by

  these angular speed sensors define after integration

  tion the position of the line of sight in space, this information being transmitted to the vision simulator 24 of the

  fig 1 In the same way as what has been described in reference

  In FIG. 1, the vision simulator 24 provides the

  television monitor 16 corresponding video signals

  dance to the direction established for the line of sight in space.
