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.

Abstract: The present application discloses a method and apparatus for annotating point cloud data. A specific implementation of the method includes: collecting data in a given scenario by using a laser radar and a non-laser radar sensor to respectively obtain point cloud data and sensor data; segmenting and tracking the point cloud data to obtain point cloud segmentation and tracking results; recognizing and tracking feature objects in the sensor data to obtain feature object recognition and tracking results; correcting the point cloud segmentation and tracking results by using the feature object recognition and tracking results, to obtain confidence levels of the point cloud recognition and tracking results; and determining a point cloud segmentation and tracking result whose confidence level is greater than a confidence level threshold as a point cloud annotation result. This implementation reduces the amount of manual work required for annotating point cloud data, thereby reducing the annotation costs.
