Abstract
This invention relates to a method, apparatus, device, medium, and vehicle for generating reference lines for autonomous driving, comprising: acquiring navigation information and an SD map of an autonomous vehicle; extracting spatial feature data based on the SD map; obtaining temporal feature data based on the navigation information; fusing the spatial feature data and the temporal feature data to obtain fused feature data; and generating a target reference line for the autonomous vehicle based on the fused feature data. Through embodiments of this invention, end-to-end reference line generation can be achieved by combining navigation information and an SD map, enabling reasonable and accurate planning of reference lines.
