The invention provides an automatic driving road point data acquisition and maintenance method for a non-fixed road, and belongs to the technical field of automobile automatic driving. According to the method, road piles are installed on the two sides of the non-fixed road, ultrahigh-frequency passive radio frequency chips are embedded into the road piles and existing traffic sign facilities, unique IDs, position information, road attributes, environment images and the like of the chips are collected, data binding is conducted with the IDs of the chips as indexes, and road point data of the electronic road sign are formed; the road point data is corrected to generate a road map, and the road map is issued to the automatic driving vehicle; an ultrahigh-frequency RFID reader is installed onthe automatic driving vehicle, the chip ID of the electronic road sign can be detected, positioning is conducted in a road map, and the abnormal road point data are detected in the driving process forroad maintenance. According to the invention, the equipment cost is low, the acquired map data volume is greatly reduced, the data updating is fast, accurate positioning and navigation data can be obtained and the reliability and the safety of the automatic driving system are improved.
本发明提出一种非固定道路的自动驾驶路点数据采集与维护方法,属于汽车自动驾驶技术领域。本发明方法在非固定道路两侧安装路桩,在路桩和现有交通标志设施上嵌入超高频无源无线射频芯片,采集芯片唯一ID、位置信息、道路属性及环境图像等,并以芯片ID为索引进行数据绑定,形成电子路标的路点数据;校正路点数据后生成道路地图,发布到自动驾驶车辆;自动驾驶车辆安装超高频RFID阅读器,能够检测电子路标的芯片ID,在道路地图中进行定位,同时在驾驶过程还检测异常路点数据进行道路维护。本发明所使用的设备成本低,采集的地图数据量大大减少,数据更新快,能获得精准的定位导航数据,提高了自动驾驶系统的可靠性与安全性。
