Federal Aviation Administration –
CAMI/HMD Study
The
image below was taken from a "signpost in the sky" system
ZedaSoft built for the FAA's CAMI division.
The FAA wanted to evaluate the benefits of a helmet-mounted display
system that showed navigation symbology overlaying terrain. ZedaSoft put
together a system using Intel hardware running RedHat Linux 7.2. The
video subsystem was based on 64MB GeForce3 cards. Custom software was
implemented in C++. SGI's OpenGL Performer was used to render the terrain
and symbology overlay. The image shown is one of two channels that were
output to a Kaiser helmet-mounted binocular display. Head position and
orientation data were provided by a Polhemus serial head tracking system
mounted to the helmet.
Three PCs were used in this system. Two PCs generated the left and right
eye video channels, while the third combined the simulation host position
data with reported head orientation to generate the composite eye point
that defined the view position. Final binocular viewing correction was
performed in the software that generated the left and right eye video.
The FAA provided the visual scene database. This database was obviously
built with a low level-of-detail except around airports.
