Problems solved by technology

However, this method relies on the information reporting of the vehicles. Once any of the vehicles cannot report its own position, it means that it cannot be sensed by other vehicles and becomes a safety hazard.

Through the embodiment of the invention, the safety performance ofthe system can be improved.

Description

technical field [0001] The present application relates to the technical field of road condition information processing, in particular to a road condition information processing method, device and system. Background technique [0002] In the fields of autonomous driving and intelligent transportation, highly intelligent autonomous vehicles can effectively perceive their surrounding environment, obtain information such as the type, position, orientation, size, and speed of nearby targets, and make reasonable decisions based on their own driving status. Driving decision-making completes the work of vehicle driving, thereby replacing manual driving labor and realizing a highly automated driving process. [0003] At present, there are two common autonomous driving perception systems: vehicle sensor network perception and vehicle communication network perception. In the way of on-board sensor network perception, self-driving cars need to be equipped with numerous sensors (lidar, ...
