A panoramic video acquisition and transmission device and method based on Beidou control

Abstract

A Beidou satellite control based panoramic video collection and transmission device and method includes a Beidou satellite information transmission module and the like. According to the invention, a control link adopts a 2-generation Beidou satellite based short message communication function, a wireless public network is adopted as a service link and uniform control of command information and service information is implemented through a network management agency. The uniform control of command information and service information includes two parts of work content including network managementcontrol and service transmission. In the first part, the Beidou satellite information transmission module is taken as a control channel and a remote control network management agency module performs centralized control on an image collection module, a video processing module and a wireless transmission module in a local terminal device. In the second part, a local image collection module transmitscollected VS video streams to a splicing and correction module in real time. Through distortion correction, projection conversion, image registration and fusion treatment, an integral panoramic picture after splicing is output to the wireless transmission module and is transmitted to a control center via a ground wireless network. High speed real time transmission of video stream service is realized.

Description

technical field [0001] The present invention provides a panoramic video acquisition and transmission device and method. Background technique [0002] The satellite communication system has the characteristics of wide coverage, flexible terminal deployment, and is not restricted by geographical environment and transmission distance. It has obvious advantages in the field of large-scale and asymmetric communication, especially the Beidou satellite communication system with short message return function. It has more advantages in current satellite communication applications. [0003] The traditional broadband satellite communication system is not convenient for large-scale use due to the large size of the terminal and the high cost. However, the terrestrial 3G / 4G network has problems such as network blind spots and terminal disconnection, which have also been criticized. [0004] With the rapid development of China's Beidou satellite navigation system, the all-weather position...

AI Technical Summary

Problems solved by technology

[0005] The existing domestic literature mainly uses the Beidou satellite navigation system as a positioning and navigation function, and its short message function is only used as a supplement to short messages. Network management and business transmission mainly rely on the ground 3G / 4G network, which has narrow coverage, Congenital deficiencies such as inconvenient management and control, the ability and advantages of satellite network management have not been fully utilized
