| Abstract | The most important contributor today to the increasing realism of training simulators – and more specifically flight simulators – is simulation projection technology. As Image Generators (IG’s) have become more and more powerful and affordable, simulation imagery has reached a very high degree of realism through a combination of high resolution and image complexity. The combination of large fields of view and high image resolutions result in pixel counts that far exceed the ability of a single projection display. For example, a hemispherical display of 2pi steradians requires approximately 95Mpixels for 1arc -min spot resolution. It is therefore necessary to devise techniques to seamlessly tile images from multiple projectors. This paper discusses the difficulties in tiling multiple projectors and the methods currently used to overcome them. Large field of view images exhibit geometric distortions caused by system optics, projector misalignment, imperfect lenses and those from the displays themselves. The images, if uncorrected, generally have luminance and color variations both between and within each projector channel. Finally, the images must be tiled in such as way as to have smooth transitions between each of the projector channels. |
