1. A lane line labeling method applied to an electronic device, the method comprising:
acquiring a target image corresponding to a target lane;
determining motion trajectory points of a target vehicle driving on the target lane based on a global navigation satellite system and an inertial measurement unit of the target vehicle;
calculating projected pixel coordinates of the motion trajectory points on the target image;
determining target pixel coordinates corresponding to target lane lines on the target lane based on the projected pixel coordinates;
calculating target camera coordinates corresponding to the target pixel coordinates based on camera intrinsic parameters of a photographing device that captures the target image; and
labelling the target lane lines according to the target camera coordinates.
