A tool that is not flattened by people: the programmable headlights
When the car is driving at night, the high beam is turned on, which can illuminate the dark road ahead and ensure safe driving. However, if you encounter other vehicles on the road, or encounter rain and snow, this time, the high beam will not only play its due role, and may even bring potential danger.

But if you use a headlight controlled by a computer program, the situation can be quite different. It can automatically sense the objects around the car body, so that even if the driver has opened the high beam, it will not "smash a half dead" in the passing vehicles; of course, it will encounter bad weather, not to worry about irreparable traffic accidents caused by glare. .
Such "smart and intimate" headlights were developed by engineers at Carnegie Mellon University (CMU) Robotics Institute to track oncoming vehicles and automatically block parts that could cause the owner to "blind" Light. In addition, the smart headlights not only recognize external precipitation, but also shield light that may be exposed to raindrops or snow flakes due to reflections.
Unlike traditional car Xenon headlights or matrix LED headlights, the researchers used a digital light processing projector (DLP Projector), which was originally developed by Texas Instruments in the 20th century. Developed and used in the era. In the DLP system, there are thousands (and sometimes millions) of miniature mirrors that rely on a MEMS chip drive to change the position angle, and each mirror is responsible for a change in light. CMU researchers have modified the system to give more precise control over these miniature mirrors and light.
In the invention of Carnegie Mellon University, a camera can sense objects appearing in front of the car, and the millions of independent lights emitted by the lights can be controlled under the control of the computer chip according to different situations. Adjust, or extinguish or illuminate. Of course, in addition to the possible delay of 1 to 2.5 milliseconds, the system can react almost immediately to changes in the surrounding environment.
In addition to the functions described above, the headlight system can also keep the light highlighted by emitting light when the traffic/road sign is blurred due to the external environment. Even with the navigation system to better provide guidance services for car owners.
However, now the car OEM has also invested considerable energy in the development of the headlights. In addition to the matrix LED headlights currently used on the Audi A8L, BMW has even developed laser laser lighting technology. However, Srinivasa Narasimhan, a professor at the Robotics Research Center at Carnegie Mellon University, said in an interview that most of the headlight systems are too limited and can only have one or two specific functions. The programmable control light system developed by CMU can take into account multiple functions and needs.
Researchers at Carnegie Mellon University recently unveiled the headlight technology at the "European Conference on Computer Vision" in Zurich. However, due to the huge size of the concept products, only heavy-duty commercial vehicles such as trucks or buses can adapt to these smart lights, but team members hope to reduce the size of the product in the future to meet the needs of lightweight vehicles.
