Abstract
A method and a device for detecting a road boundary are provided. The method includes: sending, at a current detection moment, multiple detection beams to a road where a target vehicle is located by using a detection device installed on the target vehicle; obtaining echo signals of the detection beams reflected by the road; determining target coordinates of detection points on the road corresponding to the detection beams in the same coordinate system based on the echo signals of the detection beams; and determining a road boundary on the road based on the target coordinates of the detection points.
