Abstract
The invention relates to the field of methods for synthesizing an intervisibility image consisting of pixels and representing the distribution, over a terrain overflown by an aircraft, of the intervisibility zones. This is a method of synthesizing an intervisibility image consisting of pixels and representing the distribution, over a terrain overflown by an aircraft, of the zones of indirect intervisibility between the aircraft and at least one potential threat, in which, on the one hand, a danger plain color is associated with the set of zones of indirect intervisibility and, on the other hand, a safety plain color distinct from the danger plain color is associated with the set of portions of range zones of the threats that are not covered by any zone of indirect intervisibility, and, in at least one mode of the method of synthesis, said plain colors may be modulated at each pixel by a shading cue (αsha) representative of the relief of the terrain at said pixel. The method according to the invention may in particular be implemented in a cartographic accelerator card.
