摘要
该文介绍了利用无线传感网络布置传感器终端来采集声信号和图像信号。在终端节点上,利用声传感阵列采集声信号并通过信号调理电路处理再进行AD转换;在网络协调器上,利用V4L2采集图像信号并通过S3C6410的MFC模块进行H.264编码然后UDP传送。该文介绍的硬件设计实现了实时的声信号和图像的采集,最后通过信息融合可以对各类车辆目标进行分辨。
In the wireless sensor network,sensor terminals are deployed to get the acoustical signal and image signal.On the terminals,acoustical signal is collected through acoustic sensor array and then be processed through signal condition circuit for AD converting.On the coordinator,images are collected through V4L2 module,after H.264 coding,images are sent to the monitor centre through UDP.The design of the hardware system realized the acoustical signal and image signal's collecting,the fusion of the acoustical signal and image signal could finish the vehicle identification.
