An Analysis of the


Vehicle lenses are an important component of ADAS sensors, and the overall market is growing rapidly. When it comes to vehicle lens, people's attention may be more focused on the current industry chain, such as the shortage of CMOS sensors and chip semiconductors. However, there is less discussion on the production details.


Generally speaking, "car-grade" is synonymous with quality, which means strict product performance. This is because automotive products will encounter various extreme environments in various application scenarios, such as the super high temperatures generated under the sun in summer and the super low temperatures below zero in the north in winter, as well as damage caused by rain and high-pressure car washing.


In addition, automotive safety involves the life safety of drivers and passengers, so "car-grade" must ensure that the product can be used normally in these extreme environments.


Basic requirements for car-rated vehicle lenses


For vehicle lens products, the basic car standards generally include the following seven aspects:



The above are only general requirements. There will be more detailed requirements for different application environments. For example, a panoramic view requires an ultra-wide angle, which is at least 135°, and it is known that some applications require 210°.


Car-rated vehicle lenses in different application positions


As the core optical component of the camera, the optical performance of vehicle lenses in different positions will have certain differences in addition to the basic requirements for tolerating extremely hot and cold environments, service life, waterproofing, and dustproofing.


Next, we will discuss the lens characteristics of different products from front (ADAS), rear, panoramic and interior views (gesture recognition, facial recognition (eye monitoring), etc.), and intelligent electronic mirrors.


Front view (including ADAS and automatic driving sensors)


Front view cameras are mainly used in lane departure warning, intelligent high beam control, front collision warning, overspeed warning, ACC cruise control and other scenarios.


The optical requirements are:



Rear view/panoramic view


Rear view sensors are used in parking assistance, automatic parking and other scenes. The panoramic lens expands the viewing range on the basis of the rear view lens, displaying the complete vehicle environment and some simple recognition.


The requirements for rear-view and panoramic sensors for vehicle lenses are similar and can be roughly divided into the following points:



Interior view


Interior view sensors can be used in gesture recognition, human-machine interaction, as well as facial expression recognition (fatigue monitoring) and other scenes. As a result, the lens of the interior view sensor involves different bands, and different bands are selected for different identifications, requiring a certain amount of light filtration.


Intelligent electronic rearview mirror


Intelligent electronic mirrors are divided into intelligent electronic rearview mirrors (FDM) and intelligent external rearview mirrors (CMS), and the field of view of intelligent electronic rearview mirrors is three times that of traditional rearview mirrors. Nowadays, the policy of replacing vehicle external rearview mirrors with cameras is being promoted globally.


The requirements of intelligent electronic rearview mirrors for vehicle lenses are:
