(1) It is possible to suppress noise during low-light shooting, especially for the module that photographs the rear and sides of the vehicle. It is required that the image must be easily captured even at night.
(2) Another feature of the onboard camera module is that the horizontal viewing angle is expanded by 25° to 135°. The horizontal viewing angle of the camera module in the mobile phone is mostly about 55°. To achieve high resolution in wide-angle and peripheral areas, use at least five lenses.
(3) The camera body of the vehicle camera module is made of aluminum alloy die-casting, and the material cost is high. Vehicle-mounted camera module uses aluminum alloy die-casting instead of resin to ensure reliability, including the following three reasons: good heat dissipation; the use of the body as a grounding layer to suppress electromagnetic interference; the thermal stability of the shape is good.
(4) The mechanical strength and high-temperature resistance of the vehicle camera module are decisive criteria. These modules will use a special package that combines the camera with the required toughness and resistance to penetration. Since the cameras used for active driving assistance systems are components that are safe for driving, they must also be able to work reliably when the power supply system is temporarily powered off.
Due to the special requirements for stability and specification of onboard cameras, the requirements for modules and packaging are high. In addition to the higher thresholds of technology and technology, the cycle of vehicle-mounted cameras entering the front-loading market is much longer than that of other types of cameras. -win to a time period of at least one year of income generation.
