Method and system for simulating real scene through mobile terminal to achieve user interaction

The invention discloses a method and system for simulating a real scene through a mobile terminal to achieve user interaction. The method includes the steps that the mobile terminal calls a preset three-dimensional visual scene corresponding to the real scene and formulates a scene task for the three-dimensional visual scene or synthesizes the three-dimensional visual scene corresponding to the real scene through a real scene picture shot through the mobile terminal to then formulate the scene task; three-dimensional visual scene information and scene task information are uploaded to a server to obtain a sharing link; surrounding mobile terminals are found, and the sharing link is sent to the surrounding mobile terminals to invite the surrounding mobile terminals to participate; if receiving the invitation, the surrounding mobile terminals read the three-dimensional visual scene information and the scene task information stored in the server, and corresponding user personal data information is uploaded; the positions of user roles in the three-dimensional visual scene are changed according to positioning information of the mobile terminals, user operation commands are received to enable the user roles to carry out interaction, and user behaviors are recorded corresponding to the personal data information.
