 Principle of Operation
 Working
 Advantages and Disadvantages
 Present Day Applications
 Conclusion

3.  An automotive night vision system is a system to
increase a vehicle driver's perception and seeing
distance in darkness or poor weather beyond the
reach of the vehicle's headlights.
 The first car night vision system was implemented
on the Cadillac 2000 DeVille, which used infrared
technology to detect pedestrians.

4. NIGHT VISION SYSTEM IN AUTOMOBILES
works on two phenomenon :-
ACTIVE ILLUMINATION THERMAL IMAGING

5.  This system can detect pedestrians up to four times
farther than the typical headlight range even in
penetrating dense smoke.
 It actively detects people near the roadway,
highlighting potential hazards and allowing drivers to
have more time to react to them.
 Its high beam illumination warns the pedestrians as
well.

6.  Thermal imaging is a heat-sensing technology that
can see in complete darkness using temperature
difference.
 Electrical impulses are sent in the form of
temperature values to an image signal processor that
turns them into video data for presentation on a
display.

8.  Systems use an LCD that's mounted on the
dash, in the instrument cluster, or integrated
into the head unit.
 The front thermo graphic sensors detects the
heat and processes the thermo grams to
display images on LCD.
 The IR sensor attached in vehicle's grille
illuminates very high beam.

9. The Night Vision system will warn the
driver if a pedestrian is present in the
danger zone (marked in red) in front of
the vehicle.

10.  Reduce accidents.
 Greater range of about 300 meters or 1,000
feet.
 Can be switched on or off and doesn’t affect
driving style
 Works in almost every weather conditions.

11.  Higher cost of process
 Large quantity of costly and complex
equipments.
 Works poorly in warmer weather conditions
 Larger sensors are required

12.  Audi, BMW uses thermal imaging

13.  Mercedes-Benz uses active illumination

14. “ The innovation and implementation of
night vision system has a great impact
on automotive session such as saving
many lives from death reducing
accidents at night. ”
