1. The real-time control method of the three-dimensional model comprises the following steps:

  • acquiring a real-time video of a real object;

    identifying an action of a real object in a real-time video image;

    forming an action control instruction of a corresponding 3D model according to the change of the identification action, wherein the 3D model is a 3D model in a virtual world corresponding to the real object;

    transmitting the action control instruction in real time;

    calling the corresponding 3D model;

    controlling the corresponding 3D model to complete the action according to the action control instruction transmitted in real time; and

    synchronizing and outputting audio data and the motion control command, comprising;

    adding a time tag to a control instruction of a 3D model head by taking a frame as a unit;

    adding a corresponding time tag for the audio data according to the time tag of the control instruction;

    the control instruction and the audio data signal are adapted to a transmission link and output in real time;

    wherein the act of identifying the real object in the video image comprises;

    identifying a real object in an image of a real-time video according to a preset object identification strategy;

    identifying key points of a real object in the image according to a preset key point identification strategy;

    forming a plane coordinate space of the key points and a three-dimensional coordinate space of the corresponding 3D model;

    and measuring the coordinate change of the key points in the continuous images in a plane coordinate space, and recording the corresponding coordinate change of the key points in the continuous images in a three-dimensional coordinate space.
