Title:
APPARATUS FOR DISPLAYING TERRAIN ON A DISPLAY APPARATUS OF AN AIRBORNE VEHICLE
Document Type and Number:
WIPO Patent Application WO/2012/006983
Kind Code:
A3
Abstract:
The invention relates to an apparatus for displaying terrain on a display apparatus of an airborne vehicle, comprising a synthetic vision system having a terrain and obstruction database, an enhanced vision system with sensors (1) for recording terrain data, a height and position sensor (5) for determining the flight state data, a display apparatus (6), a processor (3) for fusion of the data from the synthetic vision system and from the enhanced vision system, wherein the height information which is produced by the synthetic vision system and the enhanced vision system is stored as pixels in a two-dimensional grid network, a graphics processor (4, 8) which send the terrain data produced by means of the fusion processor (3) to the display apparatus (6), taking account of the flight state data determined by means of the height and position sensor (5), characterized in that the fusion processor (3) using an error function for insertion of a pixel into the two-dimensional grid network, wherein the error function provides an estimate of the size of the respective cell in which the pixel is stored, from the distance between the pixel and the sensor position.
