Three-dimensional road modeling method and device

The invention discloses a three-dimensional (3D) road modeling method. The method comprises the following steps of: A) acquiring two-dimensional road coordinate data; B) acquiring road edge characteristic points corresponding to the two-dimensional road coordinate data according to the width of the road and the two-dimensional road coordinate data; C) determining a road surface area of the three-dimensional road according to the road edge characteristic points; and D) meshing the road surface area to obtain a three-dimensional road model. By the method, a 3D virtual road model with high simulation degree can be dynamically generated in real time according to two-dimensional map road data, so that the 3D road modeling is greatly accelerated. Thus, the method greatly improves the workability of the map road and the working efficiency of the 3D road modeling.
