Abstract

Embodiments of the present application disclose a compression method and device of a panoramic video. The method comprises: for a target panoramic video, generating each frame picture of the target panoramic picture; for each frame picture respectively, compressing the frame picture; dividing the compressed frame picture; mosaicking the pictures obtained through the dividing; generating a new panoramic video according to all the pictures obtained through the mosaicking. With the embodiments of the present application, waste of network bandwidth can be reduced.
