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  .
 

(3) Classification of in car cameras
① Classified by camera installation location :  Car mounted cameras are mainly divided into five categories :  front view cameras    surround view cameras   rear view cameras   side view cameras   and built - in cameras   Among them   front view cameras are relatively expensive and mainly used for collision warning    lane departure warning   traffic sign recognition   etc    while surround view cameras are used for panoramic parking   rear view cameras are used for reverse imaging   side view cameras are used for blind spot monitoring   and built - in cameras are used for fatigue reminders  

② Classified by the number of cameras :  divided into three categories :  monocular cameras   binocular cameras   and multi camera cameras. Both monocular and binocular lenses obtain distance information through image data collected by the camera and can play an important role in forward facing cameras .  Monocular vision calculates distance based on the size of the target after image matching    while binocular vision measures distance by calculating the disparity between two images of two cameras .  Therefore    binocular cameras have higher accuracy    more accurate measurement    and relatively higher cost    and are mainly used in high - end vehicle models .  Multi camera is a device that uses multiple different cameras to cover different ranges of scenes, enabling more accurate identification and analysis of the environment    Currently    it is only applied to individual vehicle models from some manufacturers     From the current practical application      monocular cameras    due to their low cost    can meet the needs of L3 and below when used in conjunction with millimeter wave radar and ultrasonic rada .  In the short term     monocular cameras will be the mainstream solution for car mounted cameras .
