1. A method for generating a 3D asteroid dynamic graph, comprising:
acquiring a panoramic image;
identifying and partitioning the panoramic image into a sky area, a human body area and a ground area;
calculating a panoramic depth map for the sky area, the human body area and the ground area respectively;
transforming the panoramic image and the panoramic depth map respectively to generate an asteroid image and an asteroid depth map;
generating an asteroid view under a virtual viewpoint;
generating a 3D asteroid dynamic graph by rendering a plurality of asteroid views under a plurality of virtual viewpoints.
