摘要
根据目前国内穿戴式多媒体系统发展的现状,设计实现了一种实时性的头戴式无线音视频拍摄、存储、传输系统;将嵌入式计算机、基于H.264视频压缩技术、Wi-Fi无线传输技术相结合;头戴终端挂载了高清摄像头,采用了海思Hi3516为其核心组件,该组件集成了ARM+DSP的处理器,搭载了嵌入式Linux操作系统,功能强大。使用者在佩带头戴终端工作时,能够完全释放双手,提高工作效率,适合在新闻报道、现场执法、军事行动等环境下使用;经反复测试.系统在全高清指标下工作稳定、运行良好。
According to current domestic wearable and multimedia system development situation, a real-time head-mounted of wireless HD video storage and transmission system is designed and implemented, which realize the function of recording, storage and transmission. This system is combined embedded computer with H. 264 video compression technology and wireless local area network （WLAN） together. The camera is attached in the head-mounted device, and the Hi3516 chip is applied in system. The Hi3516 chip integrates ARM and DSP processor. In addition, the embedded Linux operating system is employed in the chip as the software platform. With this system, users can release hands and improve work efficiency. This system can also be applied in these environment, such as news report, enforcing the law, operation military action. By means of the repeated test , system operates stably and has wide application value in Full HD standard.
