Abstract

The invention discloses a method and a system for encoding and decoding a panoramic video. The method comprises the following steps of sending, by a panoramic camera, the panoramic video to an image data caching unit after the panoramic video is shot and obtained; dividing, by the image data caching unit, the panoramic video into multiple viewpoint video sequences through an encoder according to aviewpoint division rule; encoding each viewpoint video sequence, to obtain multiple groups of encoded data; decoding, by a user device, the encoded data through a decoder, and playing the viewpoint video sequences obtained by decoding. The system comprises the panoramic camera, a communication unit and the user device. The method not only can be used for accurately judging the movement trend of auser, but also can be used for guaranteeing to decode, in real time, the panoramic video corresponding to an FOV (Field of View) in an effective viewpoint range in front of a viewpoint according to apretreatment unit, and the decoding expense is decreased.

Description

technical field [0001] The present invention relates to the technical field of panoramic video encoding and decoding, and more specifically, relates to a method and system for encoding and decoding panoramic video. Background technique [0002] Panoramic video is the main content carrier of virtual reality image display. Panoramic video is a video composed of a series of panoramic image frames, and intuitive images are dynamically displayed panoramically. The panoramic image frame is an image frame formed by recording a scene at a predetermined viewing angle, for example, the predetermined viewing angle is 360° horizontally and 180° vertically, or the predetermined viewing angle is 360° horizontally and 270° vertically, etc. After the encoder obtains the panoramic video through the panoramic camera, it needs to encode the panoramic video, and send the encoded panoramic video to the decoder for decoding. Through decoding, the user can watch the panoramic video. [0003] In t...
