In recent years, autonomous driving technology has become increasingly mature and has become one of the hottest emerging technologies in the field of consumer electronics. Not long ago, Beijing has approved Baidu to test self-driving cars on urban roads. What cutting-edge laser pointer “black technologies” are used in autonomous vehicles? Let’s take a look together.
Researchers in the camera culture department at the Massachusetts Institute of Technology’s Media Lab have developed a new foggy imaging system that can measure the distance between a car and an object shrouded in dense fog, completing tasks that cannot be done by the human eye. The research aims to integrate this technology into self-driving cars to avoid obstacles in severe weather.
The imaging sensing system uses a time-of-flight camera and can emit short-pulse lasers to objects. Then calculate the time required for the light reflection to determine the distance between the car and the object. Fog usually scatters laser light, making autonomous vehicles difficult to drive. But researchers have developed this new algorithm that can help autonomous vehicles drive safely in foggy weather, which is a huge breakthrough for autonomous vehicles.
According to a report from the US Highway Traffic Safety Administration (NHTSA) to GM, GM ’s next-generation semi-automatic cruise control system will incorporate facial recognition technology. The laser pointer system will detect the driver’s facial condition. As long as it can be confirmed that the driver keeps an eye on the road ahead during driving, the driver can take his hands off the steering wheel and let the vehicle run in cruise.
