  "textContent": "A road gradient determining method includes obtaining a three-dimensional road image formed by a two-dimensional road image of a road and laser point cloud data of the road and selecting a plurality of nodes from the three-dimensional road image as control points. The method further includes generating, according to the control points, a first spline curve indicating a road elevation and converting the first spline curve into a second spline curve indicating a road gradient. Finally, the method includes obtaining location information and determining a first road gradient according to the location information and the second spline curve. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.",
