Simulation scene three-dimensional road automatic construction method and device

Abstract

The invention provides a simulation scene three-dimensional road automatic construction method and device, and the method comprises the steps: obtaining high-precision map data for preprocessing, and creating a data element model related to a traffic scene in a three-dimensional engine; and importing the preprocessed high-precision map data into a three-dimensional engine, and constructing three-dimensional traffic scene data based on a data element model. According to the method, linear road sections, curved road sections and intersection roads in the road data are distinguished, adaptive modeling is performed, a road element model with a real visual effect is automatically constructed, meanwhile, the vertex complexity of a scene is reduced, and the rendering efficiency is improved. Compared with a traditional method that modeling personnel need to carry out manual modeling through three-dimensional software in virtual scene making, the method achieves automatic scene construction, simplifies the complexity of a scene model through a self-adaption mode, achieves rapid traffic network scene construction and high-efficiency rendering operation speed, and is suitable for large-scale popularization and application. And large-scale automatic driving simulation can be realized by combining the traffic flow and an external sensor.
