摘要
针对地铁设备巡检工作中对实时视频信息采集的需求,研究在Wi Fi(无线通信)环境下,Android(安卓)平台的地铁设备巡检移动终端的视频实时传输功能。功能实现包括视频采集端和视频播放端,视频采集端负责采集视频数据、数据压缩和数据包封装,视频播放端则负责接收解析数据包,将数据进行解码播放。在H.264视频压缩技术,实时传输协议以及流媒体服务器等相关技术的基础上,实现了Wi Fi环境下视频实时传输、播放等功能,且传输过程中视频传输流畅、延迟较小、丢包率低。
A real-time video transmission function was researched in WiFi environment on metro equipment inspection terminal with android-based platform in line with the requirements of real-time video collecting in metro equipment inspection. The function consists of a video capture terminal and a video playback terminal. The former is mainly responsible for collecting video data, data compression and data packing, and the latter for receiving and analyzing data packets, decoding the video data and playing back videos. On the basis of H.264 video compression technology, real-time transmission protocol, streaming media servers and other related technologies, the system implements the functions of real-time video transmission and playback with a smooth video transmission and low dropout rate.
