Abstract
The present disclosure provides a method, an electronic device and a storage medium for detecting a position change of a lane line. The method includes: converting a first change in a target region of first measurement data of a distance between a lane line and a reference line to a first equivalent position change, the first measurement data being obtained from first road data collected by a high-precision device on the road; correcting second measurement data of the distance with the first measurement data, the second measurement data being obtained from second road data collected by a low-precision device on the road; converting a second change of the corrected second measurement data to a second equivalent position change; and detecting a position change of the lane line in the target region based on a comparison of the first equivalent position change and the second equivalent position change.
