The key to making self－driving cars work...
is a high－precision digital map that contains
detailed information about roads and the surroundings.
Scientists in Korea are currently trying to
perfect this sort of mapping system... with
the aim of commercializing driverless cars
in the near future.
Won Ji－hyun has the details.
Here′s a car that can drive completely...
on autopilot.
It comes with multiple cameras， surround
radars and a laser scanner... that allow the
car to safely position itself on the road.
It can also generate a real－time map of
its surroundings.
″The vehicle is equipped with ultrasonic
sensors that can collect and process data
of its environment... to build a three－dimensional
map.″
These digital maps are the secret to self－driving
cars.
They contain all of the intricate information
about the road... to steer the vehicle in
the right direction.
″We have managed to achieve a number of
sensor－related technologies for self－driving
cars. But we still do not have the geographic
information for our mapping system.″
″By combining our mapping knowledge and
experience with the science institute′s
technology，... I believe Korea can soon
become a global leader of the autonomous car
industry.″
Once the mapping technology is complete，
Korean scientists hope to commercialize autonomous
cars within the next five years.
Globally， experts predict that driverless
cars will create a 42－billion－dollar industry
by the year 2025.
