Effect in night by using the infrared thermal imaging automobile
driving assistant system
·
Long detection distance:
Under the condition of good field of view, the operating distance of
the infrared thermal imaging automobile driving assistant system can be
up to 300m; under severe weather conditions (heavy rain, heavy fog,
haze, sand and dust, etc.), the operating distance of the night vision
system will be reduced to a certain extent.
For comparison, the irradiation distance of asymmetric dipped
headlight at the opposite lane side is about 60m, and that of being near
the road side is about 120m. The irradiation distance of headlight on full
beam is only 200m, which is also smaller than the operating distance of
the night vision system.
Since the operating distance of the infrared thermal imaging
automobile driving assistant system has obvious advantages as
compared to the dipped headlight and headlight on full beam, its
pre-alarm function targeted at potential risk wins the precious time for
the driver in terms of safety protection, which is very important for
avoiding traffic accidents, and safeguarding the personal and property
safety of persons in the automobile, as shown in Fig. 3.
