The invention discloses an unmanned environment perception and navigation method based on a digital twin technology, and belongs to the technical field of unmanned environment perception. Comprising the following steps: S100, acquiring data; s200, panoramic stitching is carried out; s300, identifying and classifying; s400, performing data processing to obtain basic road condition data and advanced road condition data; s500, sending the basic road condition data and the advanced road condition data to the driving unmanned vehicle; s600, constructing digital twin animation data; and S700, the unmanned vehicle computer receives and processes the digital twin logic data. A detection rod is arranged on a road and used for obtaining vehicle and road section data, the detection rod is associated with a dynamic tracking algorithm to establish the corresponding relation between a vehicle and a road section vehicle, and the specific position of the vehicle in road condition information is screened out; and finally, sensing the surrounding road condition environment based on the road condition basic data and the road condition advanced data sent by the traffic digital twin service system so as to realize environment sensing and real-time navigation planning.

    本发明的一种基于数字孪生技术的无人驾驶环境感知与导航方法,属于无人驾驶环境感知技术领域。包括:S100、获取数据;S200、全景拼接;S300、识别分类;S400、数据处理得到基础路况数据和高级路况数据;S500、发送基础路况数据和高级路况数据给行驶中的无人驾驶车辆;S600、构建数字孪生动画数据;S700、无人驾驶车辆计算机接收并处理数字孪生逻辑数据。在道路上设有探测杆用于获取车辆和路段数据,探测杆关联动态追踪算法建立该车辆与路段车辆的对应关系,从中筛选出车辆在路况信息中的具体位置,最后基于交通数字孪生服务系统发来的路况基础数据和路况高级数据感知周围路况环境,实现环境感知与实时导航规划。
