The infrared thermal imaging automobile driving assistant system
has an infrared detection capacity and can sense infrared rays out of the
range of human vision. The vehicle-mounted infrared night-vision
system is widely used. Sine the price was too high, it was mainly for
military use such as tank, armored carrier and radar vehicle. However,
with the scientific and technological progress, market popularity and
lower and lower price, common people may own the vehicle-mounted
infrared night-vision system.
3) Why to use an infrared thermal imaging automobile driving assistant
system?
During driving at night, the road condition is clear in the area before
the vehicle illuminated by the headlights on full beam. However, risks
exist in the dark area ahead.
Although automobile lighting technology has been improved a lot in
recent years, risks of driving at night are higher than that of driving in
daytime. The following situation is common: when you discover from the
light that someone is exchanging tyres at the roadside or pedestrians or
animals are being across the road, it is too late to take measures.
General Motors Corporation made a questionnaire survey from drivers
and made them grade thirty-to-forty electronic devices on automobile
based on their degree of preference. The survey result shows that most
drivers have eyes only for the automobile night-vision system and wish
to install the system on their automobiles. This is because the airbag
and ABS can work only in case of emergency of automobile but the
automobile night-vision system is an active safety device and it can
discover the accident symptom in advance to nip in the bud and improve
safety of automobile in special weather.
