The lens of the car mounted camera is the core component and the four key parameters are as follows  

Folding focal length
The size of the focal length determines the size of the field of view angle .  When the focal length value is small   the field of view angle is large   and the observed range is also large   but the resolution of distant objects is not very clear   The focal length value is large   the field of view angle is small   and the observation range is small . As long as the focal length is selected appropriately   even distant objects can be seen clearly  .  Due to the one - to - one correspondence between focal length and field of view angle   a determined focal length means a determined field of view angle    Therefore    when selecting a lens focal length   it is important to fully consider whether the observation details are important or whether a large observation range is important    If you want to see details    choose a long focal length lens   If you are watching close-up scenes     choose a wide -  angle lens with a small focal length  

Car mounted cameras are the foundation for implementing numerous warning and recognition ADAS functions  .   Among the many ADAS functions    the visual image processing system is relatively basic     and the camera is the input of the visual image processing system  . Therefore    in car cameras are essential for intelligent driving

Whether a camera performs well or not depends on 70% of its optical parameters determined by the lens. Although it is not as expensive as COMS chips in terms of unit price     performance is very important  .
