Abstract

The invention relates to a live broadcast method and system based on a virtual anchor. The method comprises the steps: obtaining movement capture data generated when a movement capture device captures the movement of a real person model; filtering and fusing the data collected by the accelerometer, the data collected by the gyroscope and the data collected by the magnetometer to obtain attitude quaternion of each joint of the real person model; generating joint point coordinate information according to the attitude quaternion; performing action matching with a preset digital human model by using the joint point coordinate information and the surface pavement data to obtain a virtual anchor; and performing real-time live broadcast by using the virtual anchor. According to the method and the device, the movement capture data is collected by utilizing the movement capture equipment, accurate and stable movement capture can be realized, and the movement capture data and the digital human model are subjected to movement matching to obtain the virtual anchor, so that the virtual anchor can make real expressions and actions of the anchor with low delay.

Description

technical field [0001] The invention relates to the technical field of network live broadcasting, in particular to a method and system for live broadcasting based on a virtual anchor. Background technique [0002] With the continuous development of the mobile Internet, webcast technology has also been rapidly improved. Among the many live broadcast modes at present, live broadcast using virtual characters has become a more popular live broadcast mode. However, as far as the current virtual live broadcast mode is concerned, due to the need for real people to interact with the audience, the virtual characters can make corresponding actions. However, during the interaction process, due to the limitations of virtual characters or motion capture equipment, the anchor’s actions cannot be perfectly integrated. In the virtual scene, the coordination of the screen is not high, resulting in a poor sense of substitution for the audience, and the overall live interaction effect is poor...
