The influence of perspective
For autonomous driving    it is not only necessary to pay attention to distant road signs    traffic lights, signs   vehicles, and other information for route planning and pre control judgment  but also to observe whether there are pedestrians in close proximity    whether there are vehicles entering at intersections    and collect information on queue cutting vehicles    pedestrians, bicycles   and other vehicles next to them for risk pre control   Currently    a single camera cannot achieve full field of view information collection    Therefore   L2 level and above will generally be equipped with medium and long - range cameras    High end vehicles will adopt a configuration of 3 front view cameras 
Main functions of vision sensor in auto drive system
Ø Obstacle detection : speed measurement and distance measurement (vehicle use requires binocular vision or above)
Ø Detection of Lane Lines : Lane Line Extraction
Ø Road information reading : traffic signal recognition   traffic sign recognition
Ø Map construction and auxiliary positioning
Detection and identification of other traffic participants - vehicle detection   pedestrian detection    animal detection
Ultra high definition pixel cameras will greatly increase the manufacturing cost of in car cameras   including raw material costs and increased computational requirements 
According to the composition of the camera module    the bottom layer is the circuit board    which is then equipped with a chip   lens holder    filter    lens    and lens cylinder   From the perspective of the cost of lens modules    the chip accounts for the largest proportion   almost reaching over 50%    The chip of the lens   also known as the image sensor    will increase manufacturing costs as pixel demand increases
