Abstract
A method, an apparatus and a device for detecting lane boundaries are provided. The method includes: obtaining a current image of a lane, and extracting brightness jump points in the image by filtering the image; filtering out noise points from the brightness jump points, and determining remaining brightness jump points as edge points to form groups of the edge points, where a connection line of edge points in the same group forms one edge line; recognizing edge lines of the lane boundaries from edge lines; and grouping the edge lines of the lane boundaries, and recognizing edge lines in each group as edge lines of one lane boundary. Based on the method, a calculation for detecting the lane boundaries is simpler, and calculation resources and time consumed in detecting the lane boundaries are reduced to detect the lane boundaries accurately and quickly.
