Vehicle Interior Rearview Mirror Camera High Definition Car Camera Set

Vehicle Camera Moitoring System High definition display screen reverse image 7 - inch 9-inch 10.1 - inch truck

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 .

At present    forward and surround vision are the most widely used camera applications

3. Side view camera
Installation position :  at the left and right rearview mirrors or below the vehicle body
Side view cameras are mainly used for blind spot monitoring of BSD    and can achieve forward or backward viewing depending on the installation position    At present    most car manufacturers choose to install the rearview mirror on both sides of the car below   which may replace the inverted rearview mirror in the future

4. Rear view camera
Installation position :  Generally installed on the trunk or rear windshield
The rear view camera is mainly used during the reverse process to facilitate the driver's capture of the rear image and achieve parking assistance function .

5. Built in camera
Installation position :  There is no fixed position   it can be found in the steering wheel    above the inner rearview mirror   at the A - pillar or integrated into the instrument display screen .

Due to the fact that existing autonomous driving is only located at level L2 - 3Human driver intervention is also required    Therefore  the driver monitoring system DMS has become a solution in ADAS   The existing DMS solutions mainly rely on AI recognition using near - infrared cameras   This camera is located in front of the driver and can capture complete facial information

In addition   some manufacturers have extended from DMS systems to OMS passenger monitoring systems    which can effectively prevent rear row children or children from being forgotten in the car

Of course   the ADAS sensor of a car is not limited to the five types of cameras mentioned above   in order to achieve redundancy in the perception system and ensure safety   The host factory will basically adopt multi - sensor fusion combining millimeter wave   laser   ultrasonic and other radars   and the number of cameras is likely to increase
