Patent ID: 8823555

Claim:
A device for displaying terrain on a display device of an aircraft, comprising a synthetic vision system having a terrain and obstacle database; an enhanced vision system having sensors configured to acquire terrain data; a height and position sensor configured to determine flight status data; a display device; a fusion processor coupled to the synthetic and enhanced vision systems, wherein the fusion processor is configured to fuse the data from the synthetic and enhanced vision systems to generate terrain data, wherein height information generated by the synthetic and enhanced vision systems is stored as pixels in a two-dimensional grid network; and a graphics processor configured to send the terrain data generated by the fusion processor to the display device while taking into account the flight status data determined by the height and position sensor, wherein the fusion processor is configured to use an error function when inserting a pixel into the two-dimensional grid network, the error function providing an estimate of the size of the respective cell, in which the pixel is stored, from the distance of the pixel from the sensor position.
