The embodiment of the invention discloses a lane line data detection method and device, equipment and a medium. The method comprises the following steps: acquiring data of a current road section where an automatic driving vehicle is located and to-be-searched data; wherein the current road section data is obtained based on a high-precision map, and the to-be-searched data comprises a to-be-searched lane; determining a lane line set according to the current road section data and the to-be-searched data; wherein the lane line set comprises a plurality of lane line coordinate points; determining a projection coordinate point and a target coordinate point of the automatic driving vehicle on each lane line based on the coordinate points of the plurality of lane lines in the lane line set; and determining a lane line data list of the to-be-searched lane according to the projection coordinate point, the target coordinate point and the lane line set. According to the technical scheme, the lane line data detection accuracy and reliability of the automatic driving vehicle under complex traffic environment and severe weather conditions can be improved, and powerful support is provided for decision making, path planning and safe driving of the automatic driving vehicle.

    本发明实施例公开了一种车道线数据检测方法、装置、设备及介质。其中,该方法包括:获取自动驾驶车辆所在的当前路段数据和待搜索数据;其中,当前路段数据是基于高精地图获取的,待搜索数据包括待搜索车道;根据当前路段数据和待搜索数据确定车道线集合;其中,所道线集合中包括多个车道线坐标点;基于车道线集合中多个车道线的坐标点确定自动驾驶车辆在每个车道线上的投影坐标点和目标坐标点;根据投影坐标点、目标坐标点及车道线集合确定待搜索车道的车道线数据列表。本技术方案,能够提高自动驾驶车辆在复杂交通环境和恶劣天气条件下的车道线数据检测准确性和可靠性,为自动驾驶车辆的决策、路径规划及安全行驶提供有力支持。
