The invention discloses an automatic driving
environmental perception system based on vehicle-road coordination. The
system includes a roadside sensor, a roadside
processing unit and a roadside
communication unit which are arranged on a road segment divided according to a
set distance. The roadside sensor includes a camera, a
laser radar, and a
microwave radar, and is used for acquiring road information of a road. The roadside
processing unit is used for receiving the road information acquired by the roadside sensor, recognizing and
processing the road information, then converting the road information into a united world coordinate
system, fusing and marking the converted data in a high-precision map, splicing the high-precision maps of adjacent road sections to form semantic road environment information, and transmitting the semantic road environment information to the roadside
communication unit. The roadside
communication unit is used for sending out the semantic road environment information by using
wireless communication technology. The automatic driving
environmental perception system, by using the roadside sensor, updates the high-precision map in real time according to theacquired road dynamic characteristic data on the basis of the original high-precision map, so as to provide a global
environmental perception capability for the
safe driving of an autonomous vehicle.
