Virtual Reality Applications to Aerospace
Dr. Venkat Devarajan, Director of VEL, was the chief architect of
TOPSCENE, a system designed to provide the
ability for military pilots to train for situational awareness on air to ground
missions. The technology was developed when Dr. Devarajan worked for LTV
Missiles and Electronics which eventually became Lockheed Martin Missiles and
Fire Control Systems, Dallas, TX. It was the first time that aerial imagery and
satellite imagery were stored on mass storage devices, accessed and manipulated
in real time to give the illusion of smooth motion over gaming areas. As a side
product some of earliest Digital Photogrammetry technology was developed at Dr.
Devarajanís lab at Lockheed Martin. TOPSCENE has since then found wide
acceptance in all services of the US military and Digital Photogrammetry has
Since coming to UT Arlington as a Professor,
Dr. Devarajan has continued to work with his former TOPSCENE group to develop
data bases for TOPSCENE in a more efficient manner and to increase the inherent
accuracy in targeting.
Computer Vision work in Mechanical CAD
In mid 1990ís Dr. Devarajan
and his students worked on the classical problem of extracting intelligent
information from the lines, arcs and circles of a typical 2D Mechanical CAD
drawings and attempt to create design feature based 3 D models which were just
then coming in to prominence. The initial R&D work was sufficiently promising
for Dr. Devarajan to start a company called Imagecom Inc. The company then
continued to develop the idea in to patentable technology and a product called
FlexiDesign. Imagecom is now a small
business with several customers in commercial and military market.
From an R&D point of view,
the problem that the students affiliated with VEL that worked on the 2D to 3D
conversion is one of computer vision. Publications related to this technology
