Device for external visual simulation in a shooting trainer

The present invention relates to a device according to the preamble of claim T. Zur It is known, for example, from US Pat. No. 2,662,305 to simulate a combat situation To project an image of a landscape and a target onto a cylindrical projection screen. There mechanical means are also already specified, for example to cover the target by the Simulate landscape. Apart from the fact that the known device is mechanically very complex and so that can only be realized very costly, the achievable representation is with an actual one Combat situation can only be compared to a limited extent, as targets and landscape are only visually superimposed. Combat tactics for firearm crews, especially tank crews, require the Gun commanders or tank commanders clarify the battle situation through direct eye observation can, whereby the simulation of the combat situation as realistically as possible, even with a shooting trainer should be.

It is therefore the object of the present invention to simulate the external view on the basis of the known device Realized as realistically and inexpensively as possible with a shooting trainer. This object is achieved according to the invention characterized in claim 1. More beneficial

Refinements of the invention are set out in the subclaims removable.

In the external visual simulation according to the invention made use of a visual simulation, the object the older German patent application P 31 33 866.6 forms. There are both the one to be displayed Background as well as the targets moving in the background are digitally saved. About that In addition, both the targets and individual objects in the background, such as bushes, houses, etc. are included provided with distance information so that when the target and the individual object are superimposed in terms of coordinates A decision can be made in the background, whether the goal is in front of or behind the individual object is to be represented. In addition, there are target silhouettes in different views and target courses can easily be generated by computer, with these means a realistic visual simulation is in easily possible. In contrast to this older proposal, in which the view is through directional optics is simulated for a gunner, in which the TV monitor is arranged in the field of view of the directional optics, should here, however, the unobstructed view of the outside for a gun leader or tank commander can be simulated. to for this purpose, not just a section of the background but the entire background is covered Large-screen TV projectors thrown onto a curved projection screen, with the gun leader or Tank commander is located in the center of this projection.

Using the only figure in the accompanying drawing the device according to the invention for external visual simulation is explained in more detail below.

According to the single figure, a digital panorama image memory 10 is arranged, which ? .. B. a panorama of 150 °

stores in azimuth and 20 ° in elevation. This image memory 10 is divided into three frame memories I to III which save partial panoramas with an azimuth of 50 ° and an elevation of 20 °. A target memory 12 contains one or more destinations stored digitally ··. The partial panoramas and the target (s) are under Control by a process computer 14, which assigns the target in terms of coordinates to the panorama, in image synthesis devices 16, 16 'and 16' 'linked together and after a subsequent digital / video conversion in converters 18, 18 'and 18' · three large-screen TV projectors 20, 20 'and 20' ". The projectors 20, 20 'and 20" are perpendicular to the Axis A standing in the plane of the drawing, can be pivoted through an angle such that the images projected by them BI, BII and BIII line up seamlessly on the cylindrical projection screen 22. By sufficient Interface effects between the individual images BI to BIII can be adjusted well Reduce the minimum. The observer, i.e. the gun leader or tank commander, is with his Eye also in this axis A.

It is obvious that instead of the three large-screen TV projectors more or fewer projectors can also be used. In addition, it would be the same possible, the panorama image shown on the projection screen 2-2 not only in the azimuth direction by several Combine individual images but also in elevation using several individual images.
