Generating three-dimensional virtual scene
First Claim
1. A method for generating a three-dimensional (3D) virtual scene, comprising:
- identifying a two-dimensional (2D) object in a 2D picture of any of a plurality of picture types and a position of the 2D object in the 2D picture, the plurality of picture types including every type of picture with individually recognizable 2D objects;
obtaining a three-dimensional model of a 3D object corresponding to the 2D object based on a mapping relationship between positions and colors of color blocks in the 2D object and the 3D object, the colors being any of a plurality of colors in the visible spectrum;
calculating a corresponding position of the 3D object corresponding to the 2D object in a horizontal plane of the 3D scene according to the position of the 2D object in the 2D picture based on a mapping relationship determined between the 2D picture and an area of the horizontal plane of the 3D scene; and
simulating a falling of the model of the 3D object onto the 3D scene from a predetermined height above the 3D scene, wherein the position of the landing point of the model of the 3D object in the horizontal plane is the corresponding position of the 3D object in the horizontal plane of the 3D scene.

Abstract
A method and system for generating a three-dimensional (3D) virtual scene are disclosed. The method includes: identifying a two-dimensional (2D) object in a 2D picture and the position of the 2D object in the 2D picture; obtaining the three-dimensional model of the 3D object corresponding to the 2D object; calculating the corresponding position of the 3D object corresponding to the 2D object in the horizontal plane of the 3D scene according to the position of the 2D object in the picture; and simulating the falling of the model of the 3D object onto the 3D scene from a predetermined height above the 3D scene, wherein the position of the landing point the model of the 3D object in the horizontal plane is the corresponding position of the 3D object in the horizontal plane of the 3D scene.
