摘要
现场图像和语音信息的采集是侦察机器人的重要功能。本文研究微型侦察机器人的无线音视频传输系统。硬件方面以i.MX283处理器作为主控制器,包括视频采集、音频采集解码和无线通信等功能模块;软件方面以嵌入式Linux作为操作系统平台,通过V4L2、ALSA接口采集音视频数据,并根据RTSP/RTP协议搭建流媒体服务器。本文实现了机器人本体平台的音视频流畅稳定的传输,为机器人远程操控提供可靠保障。
The important function of reconnaissance robot is to collect audio and video information in its worksite. This paper studies the wireless audio and video transmission system for micro reconnaissance robots. For hardware design, i.MX283 is used as the main controller, it is equipped with some functional modules such as video capture module, audio capture module, and wireless communication module. For software design, embedded Linux is used as the operating system platform. The audio and video data is captured through the V4L2 and ALSA interface, and a streaming media server is built based on RTSP/RTP protocol. This paper realizes a smooth and stable transmission system of audio and video on the platform of the micro reconnaissance robot, and provides reliable guarantee for robot＇s remote control.
