Front view camera :  mainly installed on the front windshield to achieve visual perception and recognition functions during driving   It can be divided into front view main camera  front view narrow angle camera   and front view wide angle camera according to their functions
Front facing main camera :  This camera is used as the main camera in the ADAS system of L2   The field of view angles are generally 30 °   50 °  60 °   100 °   and 120 °  and the detection distance is generally 150 - 170 meters    The camera output format is RCCB or RCCC 

Forward looking wide - angle camera :  The main function of this camera is to recognize objects that are close in distance   mainly used in urban road conditions   low - speed driving and other scenes   Its field of view angle is between 120 °  - 150 °    and the detection distance is about 50 meters  After the large - scale installation of the 8MP lens in subsequent vehicles   this camera is not needed

Front view narrow angle camera :  The main function of this camera is to recognize targets such as traffic lights and pedestrians   Generally   narrow angle lenses are used  and lenses around 30 - 40 ° can be selected   And the pixels of this lens are generally the same as those of the front facing main camera  The camera adopts a narrow angle  has higher pixel density and farther detection distance   and can generally detect up to 250 meters or even longer distances

After installing an 8MP camera   the FOV of the front facing main camera can reach 120 °   which may not be needed anymore  The detection distance is around 60 meters

Surround camera :  mainly installed around the vehicle body   usually using 4 - 8 cameras   which can be divided into forward facing fisheye camera   left facing fisheye camera    right facing fisheye camera   and rear facing fisheye camera   Used for displaying panoramic panoramic view function   as well as visual perception and object detection integrating parking function    The commonly used color matrix is RGGB  as there is a need for color restoration
