A method and device for determining a road gradient, a storage medium, and a computer device. The method comprises: acquiring a three-dimensional road line constituted by a two-dimensional road line and laser cloud point data of a road (S202); selecting multiple nodes on the three-dimensional road line as control points for a spline curve (S204); drawing on the basis of the control points a first spline curve used for expressing road elevation (S206); converting the first spline curve into a second spline curve used for expressing road gradient (S208); acquiring location information (S210); and determining a first road gradient on the basis of the location information and of the second spline curve (S212). This increases the precision of the road gradient.
