基于嵌入式Linux的船舶视频监控系统研究

Research on ship video surveillance system based on embedded Linux

在我国航运领域,船舶管理水平亟待提高,船舶防碰撞、船舱货物监控,船舶管理等问题需要研究。本文实现了一种通过CDMA网络远程实时监控船舶情况的嵌入式视频监控系统。利用ARM处理器、USB摄像头和MJPG-streamer构建视频采集端并将采集图像传输到云服务器,服务器端与用Qt搭建的船舶及地面客户端建立连接、传输视频图像,客户端显示监控视频。在网络稳定、单张图片内存大小不超过65k的情况下,客户端显示视频流畅。

In China's shipping industry,the level of ship management needs to be improved.Issues such as ship anti-collision,cabin cargo monitoring,and ship management need to be studied.In this paper,an embedded video surveillance system for remote real-time monitoring of ships through CDMA network is proposed and implemented.The ARM processor,USB camera and MJPGstreamer are used to construct the video acquisition terminal and transmit the collected image to the cloud server.The server is connected to the ship and ground client built with Qt to transmit the video image,and the client displays the monitoring video.When the network is stable and the memory size of a single picture is no more than 65 k,the client displays the video smoothly.
