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 ne

③ Classified by whether the camera has algorithm functions : Currently   some car mounted cameras (such as BMW X5 using ZF S-Cam4 three camera) have Mobileye EyeQ4 processors that can achieve visual processing functions ;  Another solution    such as Tesla's three camera   removes the computing function and only performs image capture for the car mounted camera  . The advantage of this solution is that the cost is reduced by about 60% compared to traditional solutions.

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 40-70
