5G-based unmanned aerial vehicle multi-channel video transmission and splicing system

Abstract

The invention relates to a 5G-based unmanned aerial vehicle multi-channel video transmission and splicing system. The 5G-based unmanned aerial vehicle multi-channel video transmission and splicing system comprises four subsystems, namely an unmanned aerial vehicle video data acquisition and transmission subsystem, a 5G public network communication subsystem, a server subsystem and a user subsystem. According to the invention, an overall system architecture combining unmanned aerial vehicle multi-channel video real-time transmission and a video stitching technology is constructed, high-real-time transmission of multi-channel video data is realized by utilizing the characteristics of high speed, large bandwidth and low time delay of a 5G technology, and a high-quality video stitching technology is realized at a server side. The problems of limited power of transmitting equipment, high power consumption, limited endurance time, limited communication link bandwidth and the like of unmanned aerial vehicle video transmission services under 4G communication conditions are solved, a new solution for unmanned aerial vehicle video acquisition services is provided for users, real-time video stitching of multiple paths of video streams is realized, and a support is provided for development of unmanned aerial vehicle video acquisition business in the future.

Description

technical field [0001] The present invention relates to the technical field of aviation communication. Aiming at the current problems in the application scene of multi-channel video data collection and splicing of unmanned aerial vehicles, a design scheme of a 5G-based multi-channel video transmission and splicing system for unmanned aerial vehicles is proposed. Background technique [0002] Due to its small size and strong mobility, the application of UAVs in the field of video detection has a reliable application prospect and broad commercial investment value. But at the same time, under the condition of 4G communication, UAV video transmission has the following problems: (1) UAV has limited load capacity, and the video acquisition equipment first considers the weight issue; (2) The power of the transmitting device is limited, when carrying local packets When there is a large delay in network data packets, it will cause interference to the command issuance and UAV control;...
