The invention provides a control signal acquisition method and an automatic driving model training method, relates to the technical field of artificial intelligence, in particular to the technical fields of computer vision, deep learning and the like, and can be applied to scenes such as automatic driving and the like. The control signal acquisition method comprises: determining a plurality of road levels and respective road nodes of the plurality of road levels, the plurality of road levels having different association degrees with a planned route of a vehicle, and the road nodes representing a section of road located in the same lane; coding the position information of the respective road nodes of the plurality of road levels to obtain respective road coding features of the plurality of road levels; based on a preset road query feature and the respective road coding features of the plurality of road levels, obtaining a road comprehensive feature; and generating an automatic driving control signal based on the road comprehensive characteristics.

    本公开提供了一种控制信号获取方法和自动驾驶模型的训练方法,涉及人工智能技术领域,具体涉及计算机视觉、深度学习等技术领域,可应用于自动驾驶等场景。控制信号获取方法包括:确定多个道路层级和多个道路层级各自的道路节点,多个道路层级与车辆的规划路线具有不同关联程度,道路节点表征位于同一车道内的一段道路;将多个道路层级各自的道路节点的位置信息进行编码,得到多个道路层级各自的道路编码特征;基于预设的道路查询特征和多个道路层级各自的道路编码特征,获取道路综合特征;以及基于道路综合特征,生成自动驾驶控制信号。
