Abstract
In a road shoulder extraction method, three-dimensional scan data of a plurality of frames is obtained. At least one high spatial point in the three-dimensional scan data of the plurality of frames is removed, to obtain three-dimensional scan data sets of the plurality of frames. A search is performed for a curvature change point and an elevation change point in each of the three-dimensional scan data sets of the plurality of frames. A search is performed for a road shoulder location point in the three-dimensional scan data set of each of the plurality of frames according to the curvature change point and the elevation change point in the three-dimensional scan data set of the respective frame. The road shoulder location point in the three-dimensional scan data set of each of the plurality of frames is extracted according to a preset algorithm. The extracted road shoulder location points are connected to obtain a road shoulder line.
