Transcript of Space Vision System (SVS)

Description The Space Vision System The Space Vision System (SVS) was built in 1983 at Canada's National Research Council laboratories and built by NEPTEC. This system uses TV cameras as sensors. These cameras monitor a pattern of special target dots placed on the object to be tracked. It provides information on the exact location, orientation, motion of a specified target. The system also tracks the changing position of the dots, calculates the location and orientation of the object, and presents this information to the operator in the form of both graphical and textual cues. This information can be used to position and orient a payload using the Canadarm or the Canadarm2, or to join two objects as in the case of Space Station assembly. With the Space Vision System astronauts can perform precise tasks in extreme conditions. Basic designs created by the National Research Council of Canada in the 1970's then in 1990 Neptec was founded to continue work on the SVS "We inherited ASVS technology from our predecessor, Leigh Instruments, the people who originally built the vision system for the NRCC way back when. When we first started with ASVS, it was a piece of lab software with potential. At the time, we had no idea it would turn into a piece of shuttle equipment".

- John Schneider,Neptec Software Manager “Neptec is a prime example of a Canadian success story. The Canadian Space Agency is very proud to see Neptec being recognized as a driving force of innovation, both in Canada and internationally. This recognition is even more important to Canada as Neptec is the first non-U.S. company to receive this prestigious award from NASA. It truly shows the value Canada offers to the international space program.”

-Steve MacLean, President of the Canadian Space Agency First tested by Canadian Astronaut Steve MacLean in October 1992 with the Canadarm For the International Space Station, Canada agreed to develop, build, and operate the mobile servicing system (MSS). The MSS included a Mobile Base System, two manipulators, and the CSVS.

The estimated cost of building, testing and operating MSS hardware is an estimated $1.4 billion Canada In Space IMPACTS Positive to society and the environment Canadian astronaut Chris Hadfield described Space as "a surreal place to work, with no familiar landmarks or objects to give perspective and depth." Presented By Maire Balzan, Jodi Crawford and Colin Simmons Negative Rocket Engines

engines release gases that break ozone molecules
ozone protects us from UV-B radiation
some gases released into the stratosphere, which causes harm faster Waste from Production several half-scale models of the ISS had to be built
these were built only to make testing realistic
the models were used very few times, because their use was so specific The End.
Thank you for listening! Automobile Industry idea originated from
used by assembly line robots
used to test sheet metal for imperfections
used to take more accurate results in crash tests Military military uses it for 3D target scanning and recognition Law Enforcement used to gather hard to get evidence from crime scenes
e.g. shoe or finger prints History used to preserve historical treasures
creates 3D scans of artifacts and buildings
creates virtual reality versions
subjects include famous paintings at the Louvre and medieval monasteries in Italy "Space is probably the most extreme visual environment you can get. There are few visual cues to gauge depth, distance, or speed, and light levels range from blinding sunlight to pitch black." – Jennifer Coombes
SVS allows astronauts to overcome these challenges easily Space Shuttle Columbia tragedy of 2003 killed all seven crew members
NASA needed to prevent another accident
SVS’ scanning technology scans the shuttle’s outer tiles
Detects imperfections down to a millimetre Space Work Space Work work needed on space probes such as Hubble Telescope
SVS is the key to updating these
can be used to replace batteries, lenses, or other mechanical or technological pieces
helped to build the International Space Station the SVS has had 5 shuttle flights
each flight poses risk to the environment
