| 摘 要： | 针对移动机器人的目标声源定向问题,应用四元球面麦克风阵列建立了一套空间声源定向系统。为了解决通过阵列的时延值预测出目标声源方向的问题,提出了神经网络算法,并设计了双隐层BP神经网络。通过Matlab仿真验证了该网络可以实现近场和远场的声源定向,并在机器人本体上进行了实验测试,证明了该系统的实用性。

| Abstract: | For the mobile robot sound source orientation,this paper uses four elements spherical microphone array to establish a spatial sound source target orientation system.In order to predict the direction of sound source target by the time delay of microphone array,the neural network algorithm is proposed in this paper.Designing a BP neural network which has two hidden layer and simulating it by Matlab toolbox.The experimental results show that the network can orient the sound source target in close field or in far field,then text it on the robot,the more show that the network is practical. |
