Problems solved by technology

The automatic driving perception system in the prior art is additionally installed on the top of the vehicle after the vehicle leaves the factory. The range of perception is limited. On the other hand, the sensors of the autonomous driving perception system have the characteristics of heterogeneity, polymorphism, and incompleteness. Various sensors are interfered by different factors, and will show distortion or even failure, which will lead to the entire Autopilot system fails
