Abstract

This paper presents an implementation of a streaming system which can forward live video stream to multiple users from a Phantom4, which is a drone made by DJI. We constructed the streaming server on Raspberry Pi 3 board for high mobility. Also We implemented the system so that the video stream can be played on any devices if the HTML5 standard web browser is utilized. We compiled C codes of FFmpeg open sources and installed in the Raspberry Pi3 as the streaming server and developed a Java application to execute as the integrated server that controls the other softwares on the streaming server. Also we developed an Android application which receives the live video stream from the drone and sends the streaming server continuously. The implemented system in this paper can successfully stream the live video on 24 frames per second at the resolution of 148x112 in considering the low hardware throughput of the streaming server.

본 논문은 DJI 사의 Phantom4 드론이 촬영한 라이브 영상을 여러 사용자에게 스트리밍하는 시스템을 구현한 사례를 소개한다. 스트리밍 서버는 라즈베리파이3 보드로 만들어 이동성을 높였으며, HTML5 표준 웹 브라우저를 탑재한 어떤 기기에서도 실시간으로 비디오 스트림을 재생할 수 있도록 구현하였다. 스트리밍 서버는 FFmpeg 오픈 소스를 컴파일하여 사용하였고, 전체를 제어하는 소프트웨어는 자바로 작성하였으며, 드론으로부터 비디오를 받아 스트리밍 서버로 전송하는 모듈은 안드로이드 앱으로 구현하였다. 본 논문에서 구현된 시스템은 스트리밍 서버의 낮은 처리능력에 맞추어 148x112의 해상도에서 초당 24프레임으로 성공적으로 실시간 스트리밍을 달성하였다.
