1. Introduction to in car cameras
(1) Vehicle mounted camera positioning :  Due to the mature development of camera technology   vehicle mounted cameras dominate autonomous driving solutions below L3 level .  In the autonomous vehicle   the on-board camera is the main way to collect information and analyze images   which can realize a series of functions such as vehicle recognition   pedestrian recognition   lane line recognition   etc 
(2) Car mounted camera composition :  From the perspective of the car mounted camera solution   the core hardware mainly includes lens groups (optical lenses    filters   protective films)   image sensors    image signal processors   connectors   etc .

2. Vehicle mounted camera process requirements
Compared with industrial cameras and mobile phone cameras ,  in car cameras require stable operation under various complex working conditions such as high and low temperatures   humidity, strong and low light    and vibration .  Therefore  in car cameras have higher safety levels and process performance requirements  . Considering safety factors  automobile manufacturers tend to choose component manufacturers with mature technology and guaranteed quality . Vehicle component manufacturers entering the market system and obtaining ratings require a longer certification cycle   and industry barriers are high  . In terms of performance   the current pixel requirements for in car cameras are not high   generally ranging from 300000 to 1.2 million pixels   However    in car cameras have higher requirements for detection angle and range. Wide angle lenses above 135 degrees are generally used for surround and rear view   while front view cameras have a range of 40 - 70Degree   Overall   in car cameras have high technological barriers .

3. Car mounted camera solution
Generally speaking  ADAS system bicycles are equipped with at least 6 cameras (1 front view   1 rear view  4 surround view)  . With the improvement of autonomous driving   the number of in car cameras will gradually increase  . From the perspective of Tesla series models   currently mainly 8 cameras are usedImage head   including 3 front view   3 rear view    and 2 surround view cameras . The NIO ET7 model is equipped with a total of 11 cameras   including 4 front view and 4 surround view cameras .  The number of cameras for other car companies' related models is mainly 4 - 5
