In recent years the installation rate of advanced driving
assistance systems for ADAS cameras in automobiles has been rapidly
increasing Looking at major manufacturers
Installation position : Generally located at the windshield and
interior rearview mirror
The camera used for forward driving assistance commonly referred to
as the front camera is mainly used to recognize road vehicles and
pedestrians ahead with a viewing angle of about 45 ° The image
sensor combined with a dual core MCU extended by DSP provides
incoming video frames for image processing, monitors the situation
ahead of the road, and can achieve auxiliary driving functions such
as FAM, LDW ACC etc In addition emerging night vision cameras are
generally also in this area
There are multiple classification methods for existing cameras
based on the number of CMOS lenses in the camera we classify it
into monocular and binocular According to the camera's perspective
there are wide - angle and fisheye
In this article the editor uses classification based on the
installation position of the camera and its different field of view
It is generally divided into front view rear view surround view
side view and inner view cameras The editor has compiled an
introduction to the application of some cameras in vehicles for
reference; Forward facing cameras are commonly single/binocular
cameras, which have better ranging performance but more complex
algorithms and higher prices . The number of cameras at the front
view camera is not fixed for example Tesla is equipped with three
cameras
Forward facing narrow field of view camera with a maximum
monitoring distance of 250 meters
Forward facing main field of view camera with a maximum monitoring
distance of 150 meters
Forward facing wide field of view camera with a maximum monitoring
distance of 60 meters
The forward facing camera is the core camera of ADAS covering
ranging, object recognition, road markings etc. Therefore the
algorithm is complex and the threshold is high
2 . Surround camera
Installation location : front and rear vehicle logos (or nearby) as
well as a set of cameras integrated into the left and right
rearview mirrors
The surround view camera also known as a panoramic image monitoring
system is used to identify parking lane signs road conditions and
surrounding vehicle conditions . It uses images from multiple
cameras for splicing providing a 360 degree imaging of the vehicle.
Due to the need for detecting the surrounding sound of the vehicle
it is generally installed at positions such as the vehicle logo or
grille in front of the vehicle .
