1. A virtual scene generation method, performed by a computer device, the method comprising:
acquiring three-dimensional point cloud space data of a real scene in real world and scene distribution data corresponding to the real scene, wherein the scene distribution data comprises point set data that indicates position and size information of scene objects in the real scene and the scene distribution data is distinct from the three-dimensional point cloud space data;
performing alignment on a scene area corresponding to the scene distribution data and a scene area corresponding to the three-dimensional point cloud space data to obtain a scene aligned area;
selecting the scene distribution data matching the scene aligned area from the scene distribution data to obtain aligned scene distribution data, further comprising:
selecting complete point set data from the scene distribution data when the scene aligned area has complete point set data of a first object type of scene objects;
eliminating the complete point set data from the scene distribution data when the scene aligned area has incomplete point set data of the first object type of scene objects;
selecting point set data of a second object type of scene objects in the scene aligned area from the scene distribution data;
extracting terrain features from the three-dimensional point cloud space data;
generating a three-dimensional terrain model of the real scene according to the terrain features;
extracting, from the aligned scene distribution data, scene object features of the scene objects in the real scene based on the position and size information of the scene objects in the real scene; and
generating scene object models corresponding to the scene object features in the three-dimensional terrain model to obtain a virtual scene corresponding to the real scene.
