Abstract

The embodiment of the invention provides a live video generation method and device, and relates to the technical field of video processing. The method comprises the steps of obtaining first feature data of an entity object in real time, wherein the entity object comprises a trunk, a big arm, an elbow joint and a forearm, the first feature data is used for representing rotation angles of a plurality of parts of the forearm around the axis direction, and the rotation angles of the plurality of parts of the forearm around the axis direction are in positive correlation with distances from the plurality of parts of the forearm to the elbow joint of the entity object; based on the first characteristic data obtained in real time, controlling the rotation angles of multiple parts of a forearm skin of the virtual model around the axis direction, wherein the rotation angles of the multiple parts of the forearm skin around the axis direction are in positive correlation with the distances from the multiple parts of the forearm skin to the elbow joint of the virtual model; and generating an image frame of the live video according to the virtual model. The embodiment of the invention is used for solving the problem that the action of the virtual model in the live video generated by the existing virtual live mode is unnatural.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a method and device for generating live video. Background technique [0002] In recent years, with the advancement of streaming media technology and the rapid growth of network bandwidth, the live broadcast business has become increasingly popular, and the live broadcast platform has become one of the most popular entertainment media nowadays. [0003] With the enrichment of live broadcast forms, a live broadcast method of virtual live broadcast is proposed in the prior art. The virtual live broadcast can synchronize the movement of the physical object to the virtual model in real time through 3D modeling and real-time motion capture, so that the user on the anchor side can broadcast live through the image of the virtual model, which greatly improves the flexibility of live broadcast. The method of synchronizing the motion of the physical object to the virtual m...
