Test evaluation system and method for rainy environment perception and identification capability of unmanned vehicle

Abstract

The invention discloses a test evaluation system and method for a rainy environment perception and identification capability of an unmanned vehicle. The system comprises the unmanned vehicle, a test place and a test control center, the test place comprises a rainy area test road and a no-rainy area test road, the test control center sends a test instruction to the unmanned vehicle, the unmanned vehicle drives in the corresponding rainy area test road according to the received test instruction, the test control center receives data of the unmanned vehicle in the test process, and traffic light,road signboard and barrier identifying capabilities as well as ground mark and zebra stripe identifying during ground ponding of unmanned vehicle are evaluated in the set rainfall environment. Thus,the unmanned vehicle is tested in the rainy driving condition from the aspects of traffic light and road signboards, the unmanned vehicle can plan a driving path, and the unmanned vehicle has a higherautonomous driving capability in rainy days.

Description

technical field [0001] The present invention relates to the technical field of unmanned vehicle environment perception and recognition, and in particular to a test and evaluation system and method for unmanned vehicle environment perception and recognition ability in rainy weather. Background technique [0002] At this stage, the research on autonomous driving at home and abroad is gradually deepening, mainly focusing on the performance, reliability and safety of unmanned vehicles. There are relatively few methods for evaluating the perception and recognition capabilities of unmanned vehicles in rainy areas. [0003] There are two main ways for an autonomous vehicle to obtain information about road signs and the surrounding environment. One is based on environmental perception, that is, the vehicle's perception system (including cameras, lidar, millimeter-wave radar, etc.), and the other is based on vehicle-mounted precise maps and wireless reception of information from the ...

AI Technical Summary

Problems solved by technology

[0004] At present, there are relatively few studies on the evaluation methods of the environmental perception and recognition ability of unmanned vehicles passing through the rain area, and there is a lack of standards for the ability of unmanned vehicles to safely pass through the rain area, as well as test methods and test sites that are close to the real driving environment in the rain.
