Isn't the Electronic Rearview Mirror a Backup Camera?

Often the launch of new technology, always accompanied by the voice of doubt, the most discussed is the practicality of electronic rearview mirror, and even some people joke that this is not a camera and a display screen? Of course not.

In fact, as early as the 2018 Hannover Motor Show in Germany, the relevant person in charge of the German Mekra Mecron company have mentioned on such issues. Electronic rearview mirror is a complete and technologically advanced electronic optical system, the system is mainly composed of high-definition cameras, digital vision processing system, security system and liquid crystal display screen, the visual system above the electronic rearview mirror is mainly responsible for image acquisition, and then through the digital system to process the image, to ensure that the final image presents a clear and bright picture. Then output to the cab interior display.

Among them, the digital system is one of the core keys to ensure that the system has a "practical". The camera usually takes 120 frames of pictures (our common visual picture is 30 frames), passes through the digital system of the electronic rearview mirror after processing (light and dark processing, frame rate processing to ensure clear imaging), and then transmits to the LCD screen in the driver's room. To ensure that the truck driver can still see the clear and bright pattern in the first time, regardless of the low light environment or the strong light environment.

Taking Mecron's rearview mirror digital processing system as an example, its digital system is supported by algorithms and technology provided by world-renowned graphic vision companies to ensure that the display is always able to present real-time and effective pictures, no matter when and where. Even when entering and leaving the tunnel, this light can be clearly presented than the environment that changes greatly.

In the new regulations for indirect field of view devices, the regulations impose high specifications on display brightness, Angle, picture contrast, color uniformity, and even color reproduction. This is essentially different from the reverse image and quadrilateral image system that we are familiar with in the past, which is not simply transmitted by the camera, whether it is the function, security or the final presentation of the system, the traditional camera can be replaced.
