Parallel processing architecture brings advanced vision applications
to today's cars
Technologies now on the road enable automotive design engineers
to implement robust and powerful recognition algorithms, while meeting
the stringent power consumption and operational constraints associated
with automotive design.

Safety continues to be one of the key concerns in automotive design.
In addition to keeping drivers and passengers safe, automotive manufacturers
are looking for ways to protect people outside the car-such as bicyclists
and pedestrians. While airbags and seat belts are designed to provide
protection inside the vehicle, accident avoidance equipment, through
applications such as vision-based warning systems, could provide
the ultimate solution for protecting lives both inside and out.
Analysis shows that the vast majority of accidents are caused by
human error or misjudgment. Automotive electronics that could monitor
driving conditions and warn a driver at the onset of a hazardous
situation could go a long way in preventing and mitigating human-induced
accidents.
When vision-based warning systems for drivers were first introduced,
acceptance from consumers was limited, mainly due to high costs
and a lack of reliability related to false warnings and such. Systems
have improved dramatically in recent years, and new vision systems
are now being introduced by companies such as Toyota for its flagship
Lexus LS460 (below). Current technologies enable automotive designers
to implement robust and powerful recognition algorithms while meeting
the stringent power consumption and operation constraints associated
with automotive design.
