Definitions
- the present invention relates to a device for visual simulation according to the preamble of the claim.
- DE-PS 3 133 866 it is known to load the images of a terrain, a destination and a visor into quick access memories. Additional memories can be provided for storing a projectile tracer and projectile impact effects.
- a computer loads the fast access memories in a coordinated manner in the television picture cycle.
- An image multiplexer controlled by the computer composes the different memory contents in the television image clock pixel by pixel.
- a priority control determines whether the target is to be displayed in front of or behind the site or an object in the site. For this purpose, not only is the target image provided with distance information, but also every image point of the terrain memory must have a distance coding in addition to a gray value coding which specifies its brightness. As a result, the storage requirement for the digital terrain image increases significantly.
- the least significant bit must be assigned a value of at most 50 meters. However, this requires approximately 72 distinguishable distance levels to represent a usually required distance range between 400 and approximately 4,000 meters, at least 6 bits of which are required for coding. Since 6 bits are also required for the brightness coding of a good black / white image total memory depth per pixel is 12 bits. If you limit the number of bits that determine the distance, the freedom to move the target course is also greatly restricted, which has a very disadvantageous effect, in particular if there are several destinations close together.
- each pixel of the terrain memory except with a coded brightness, i.e. with a gray value, additionally with a coded distance only one address is provided per pixel with which a transformation table is addressed, which in turn has a very fine level, e.g. with 16 bits, specifies a distance information. In extreme cases, this address can be specified by only 1 bit; expediently, however, 2 bits are added as the address of each gray value coding of the pixel.
- Figure 1a shows a section of the digital terrain memory, the image being divided into two areas A and B.
- the area A can be specified, for example, by a hill, to which a certain finite distance is assigned, while the area B can be specified, for example, by the sky, to which the distance could be assigned infinitely.
- FIG. 1b shows the silhouette of a target moving in the terrain according to FIG. 1a, the target moving on a predetermined target course, so that its distance and possibly also its contour change continuously.
- FIG. 1c shows the image composed of the two memory contents taking into account the known priority rule. For all pixels which are occupied by the target according to FIG. 1b, a check is carried out to determine whether the target distance is smaller than the off-road distance and, if so, the target point is shown. Otherwise, the terrain image point is shown.
- a computer 10 loads the various digital fast access memories in a time-coordinated manner in the TV picture clock, the contents of which are also computer-controlled merged pixel by pixel in an image multiplexer 12 in the TV picture clock.
- a terrain image memory 14 and one target image memory 16 are shown.
- Further digital fast access memories are used to store, for example, a projectile tracer, a sighting image and projectile impact effects.
- the terrain image memory 14 has a word length of 8 bits per pixel. 6 bits are used for coding a gray value of the respective pixel, ie its brightness, and the two remaining bits specify four addresses (00, 01, 10, 11) with which individual partial areas of the terrain image are marked. These addresses are used to address a transformation table 18 which contains four words with a length of, for example, 16 bits, with which the distances of different partial areas of the terrain image are encoded with high precision. The transformation table 18 can be reloaded by the computer 10 as a function of the terrain image section to be displayed.
- the device according to the invention also works when the terrain image memory is expanded by one bit per pixel, with which bit the situation shown in FIGS. 1a to 1c can be taken into account, for example.
- the above-mentioned coding of the terrain image points with two additional bits seems expedient.
- the image multiplexer 12 assembles the brightness values of the individual digital fast access memories pixel by pixel, and in addition the transformation table 18 is addressed via the address of each pixel in the terrain image memory 14 and the distance information, which is precisely coded by the 16 bits of this table, is addressed to the image multiplexer fed.
- This precisely specified distance of the image point is compared with the target distance specified by the computer and, depending on whether the target distance is greater or smaller than the off-road distance, the target image point or the terrain image point is suppressed when the image is composed.
- the image composed by the image multiplexer 12 is displayed as a composite image on a TV monitor, not shown.
