Abstract
A method and a device for generating 3-dimensional (3D) panoramic video streams, a videoconference method, and a videoconference device are disclosed. The method includes: obtaining depth information of at least two video images; obtaining image data in multiple depth positions from a corresponding video image according to the depth information of each video image; stitching data of the video images according to the obtained image data in multiple depth positions, and generating 3D panoramic video streams. The technical solution of the present invention provides users with high-resolution 3D panoramic seamless telepresence conference video images based on different display modes of different display devices.
