[0002] Traffic accidents caused by vehicles illegally loading oversized cargoes occur from time to time. Vehicles illegally loading oversized cargoes may have the tail of the cargo sticking out of the cargo compartment due to excessive cargo or excessive cargo volume. This makes it difficult for vehicles following vehicles illegally loading oversized cargoes to recognize vehicles illegally loading oversized cargoes when the intelligent driving function is turned on on open roads, posing a major traffic hazard. To ensure the safety of intelligent connected vehicles driving on open roads, a common solution in the prior art is: first, 3D targets are detected and marked through laser point clouds, and a test environment is built in a virtual simulation software. The test vehicle behavior and traffic scenes are simulated in the built virtual test environment to evaluate the system robustness and fault tolerance of the test vehicle, as well as the test vehicle's response to various anomalies; secondly, specific road conditions and dangerous scenarios are simulated in a closed field to test the vehicle's ability to respond to emergencies and safety performance; finally, the test vehicle is tested in a real traffic environment to evaluate the performance of the test vehicle in various complex environments, so as to verify the adaptability and reliability of the test vehicle in a real environment.
