Problems solved by technology

Under radio transmission, the video definition is limited, the live broadcast delay is high, the transmission security is low, and it is only valid within 10km
Existing VR videos are shot and produced with binocular cameras. After H.265 video encoding, the transmission uplink rate needs to reach 75Mbps. Due to the limitation of network transmission bandwidth, VR videos have not yet been transmitted in real time.

Abstract

The invention relates to the technical field of streaming media transmission and wireless communication, in particular to an unmanned aerial vehicle-mounted VR video acquisition and transmission device based on a 5G network, which comprises: a camera module for shooting a VR video in real time; an encoder which is used for receiving and encoding the VR video; a 5G module which is used for wireless communication; a server which is used for caching and decoding; and a user side which is used for VR glasses pull stream playing or computer display playing. The camera module, the encoder, the 5G module, the server and the user side are connected in sequence. According to the invention, the binocular camera shoots the VR video in real time, transmits the VR video to the encoding module for encoding, pushes the VR video to the cloud server, and the user side pulls the VR video from the cloud server and uses VR glasses or a display screen to watch the VR video.

Description

technical field [0001] The present invention relates to the technical field of streaming media transmission and wireless communication, in particular, to a 5G network-based VR video collection and transmission device on board a UAV. Background technique [0002] The existing real-time transmission of UAV images is mostly based on radio. Under radio transmission, the video definition is limited, the live broadcast delay is high, the transmission security is low, and it is only valid within 10km. Existing VR videos are shot and produced with binocular cameras. After H.265 video encoding, the transmission uplink rate needs to reach 75Mbps. Due to the limitation of network transmission bandwidth, VR videos have not yet been transmitted in real time. The existing 5G communication technology is developing rapidly, and the 5G industry is becoming more and more mature. The upload rate of 5G network can reach 70Mb / s, which can meet the needs of VR video transmission. [0003] The e...
