Abstract

The invention, which belongs to the technical field of unmanned driving, relates to a lane keeping ability detection system and method for unmanned driving. The system comprises an identity identification module, a forward-facing camera, a vehicle information acquisition module, an image processing module, a storage module, a transmission module, a connection circuit, and a cloud database. According to the method cooperating with the system, the ID, GPS coordinate, speed, and state of the turning light of the vehicle are obtained; the camera shoots a scene image of a road in front of the vehicle and a lane line is identified; and a lane departure distance and a departure angle of the vehicle are identified. After data collection is carried out on an unmanned driving vehicle under the certain mileage, the lane keeping ability test is performed; whether the vehicle changes the lanes is distinguished based on the turn light state; and lane keeping comfort and safety index values are calculated according to the lane departure distance and departure angle. According to the invention, the data collection and communication functions as well as the lane keeping ability detection function are realized; and the system and method have the great guidance significance in testing the unmanned driving vehicle.

Description

technical field [0001] The invention belongs to the technical field of unmanned driving, and relates to a lane keeping ability detection system and method for unmanned driving. Background technique [0002] Currently, unmanned vehicles rely on the cooperation of machine vision, radar, and global positioning systems to operate safely and autonomously without active human manipulation. Among them, the lane keeping function is one of the core functions of unmanned vehicles. It mainly detects the positional relationship between the vehicle and the lane lines on both sides through the sensor, and corrects the driving behavior of the vehicle by judging the safety of the relative distance, thereby improving the driving performance of the car. safety and comfort. [0003] Lane keeping ability is an important performance index of unmanned vehicles, and its detection and evaluation will help to effectively rate and evaluate the level of unmanned driving systems and improve the safety...
