An object importance determination method and device based on reachability analysis

By generating a reachability set relation table in the offline phase and using Monte Carlo simulation, autonomous vehicles can directly determine whether an obstacle is within the reachable area in the online phase. This solves the problems of incomplete judgment and long development cycle caused by relying on expert experience, and achieves efficient and accurate obstacle importance determination.

Abstract

The application provides a kind of object importance determination method and device based on reachability analysis, method includes: obtaining current running scene, and obtaining the reach set relationship table generated in advance in offline stage, the corresponding relationship between simulation scene initial condition and reachable region is included in reach set relationship table;Look up reach set relationship table, obtain the target simulation scene initial condition matched with current running scene, and obtain the target reachable region corresponding to target simulation scene initial condition;The position of the obstacle in the current running scene is obtained, if the position of the obstacle is in the target reachable region, then the obstacle is determined as important object.The application generates reach set relationship table in advance in offline stage, directly judges whether the obstacle in current running scene is in reachable region, reach set relationship table has good completeness, and development cycle is shorter.
