摘要
无线视觉传感器网络将监测的环境信息拓展到视觉层面,实现更精细化的监测,引发国内外研究人员的诸多关注。针对无线视觉传感器网络的特殊性,以高性能嵌入式处理器为核心设计了无线视觉传感器节点硬件,包括微处理器模块、无线收发模块、视觉信息采集模块、电源管理模块等;软件程序支持采集环境视频并进行压缩处理,获取节点间距离和节点剩余电量参数,支持自组建Ad-hoc网络进行节点间无线通信、视频传输和节点参数交换等。实验验证表明,所设计的无线视觉传感器节点运行正常,节点间距离测算以及剩余电量获取满足传感器网络应用需求。
The environmental monitoring information is expanded to the visual level by wireless visual sensor network（WVSN）.Wireless vision sensor node is designed for the specificity of WVSN.Node hardware includes the microprocessor module,wireless transceiver module,visual information acquisition module and power management module.Software part realizes the collection,transmission,receiving of visual information,and has the ability to get the node parameters of remaining battery capacity and distance between nodes.The experiment shows that the design meets the needs of WVSN applications.
