This application discloses a method and apparatus for intelligent driving data trajectory repair based on segmented point cloud registration, relating to the field of autonomous driving technology. The method includes the following steps: dividing the data segment to be repaired into multiple smaller data segments; registering each frame of point cloud data in a smaller data segment with the first frame of point cloud data in that smaller data segment to obtain a data segment repaired within the segment; and registering the point cloud data of adjacent data segments repaired within the segment on the time axis to obtain point cloud data repaired between segments. Through partial-to-global joint trajectory correction, data repair can be achieved without relying on additional hardware upgrades or external auxiliary data. This significantly improves global trajectory consistency and repair success rate, efficiently repairing trajectory deviations in existing data, avoiding data resource waste, and adapting to the repair needs of newly added data, thus greatly reducing data processing costs.
