The invention relates to the technical field of vehicles, in particular to a detection method and system applied to automatic driving road condition early warning. The detection method applied to automatic driving road condition early warning comprises the following steps: acquiring characteristic lines formed by laser emitted by four laser emitters mounted on the periphery of a vehicle through irradiation on a road surface; analyzing the characteristic line, and performing early warning on the automatic driving road condition according to an analysis result; the automatic driving road conditions include but are not limited to gradient detection, meeting early warning, tire pressure detection, road shoulder detection and back-up visual measurement. According to the method, early warning can be carried out on various road conditions of automatic driving in any environment only by installing the four laser transmitters, in addition, the characteristic lines are transmitted in real time and sensed by the side-view camera, and compared with a method for carrying out characteristic marking after the camera collects road surface information, the method has the advantages that the response is faster and more accurate. Moreover, the method can compensate the recognition of a radar for the features of a low obstacle, and improves the accuracy of APA and LKA functions.
本发明涉及车辆技术领域,特别涉及一种应用于自动驾驶路况预警的检测方法和系统。所述一种应用于自动驾驶路况预警的检测方法,包括步骤:获取安装在车辆周沿的四个激光发射器发射的激光在路面照射形成的特征线;对所述特征线进行分析,根据分析结果对自动驾驶路况做出预警;所述自动驾驶路况包括但不限于:坡度探测、会车预警、胎压检测、路肩探测、倒车可视化测量。以上方法中只需安装四个激光发射器即可在任意环境中对自动驾驶的多种路况做出预警,此外特征线是实时发射被侧视摄像头所感知,该方法比在摄像头采集到路面信息后进行特征标记的方法响应要快且准确。并且可以补偿雷达对低矮障碍物特征的识别,提升APA和LKA功能的准确性。
