Lane information extraction method and system, electronic equipment and storage medium

The embodiment of the invention discloses a lane information extraction method and system, electronic equipment and a storage medium. Ground lane marking sequence image information and vehicle-mounted track positioning data corresponding to time of ground lane marking sequence image information are obtained, semantic segmentation is performed on each frame of image, coordinates of lane marking in an image coordinate system are obtained by calculating image vanishing points of the lane marking, and the image vanishing points of the lane marking and the lane marking are obtained by combining the track positioning data. Transforming the coordinates in the image coordinate system to obtain the position of the local lane marking line in the world coordinate system; and performing covariance and distance calculation on the positions of the local lane marking lines in the world coordinate system, and performing clustering and curve fitting to obtain global lane information. The extraction cost of the lane informatio
