摘　　要：随着计算机技术和信号处理技术的发展,各种具有特殊功能的机器人应用到人们的生产生活中。听觉系统可以弥补机器人视觉系统存在的不足,使机器人在黑暗或有障碍物遮挡的环境中,利用声音信息感知环境中存在的目标,并对其定位,辅助机器人工作,尤其在灾难现场搜救、军事等领域,声源定位系统具有独特的优势。针对机器人声源定位系统进行研究,设计了基于传声器阵列的机器人声源定位系统,采用平面四元传声阵列,利用广义互相关算法,实现对声源的定位,具有较高的实用价值。With the development of computer technology and signal processing technology,all kinds of robots with special functions are applied to the production and life of people. The auditory system can make up for the deficiency existing in the robot vision system,the robot in the dark or obstructions of environment,using sound information perception environment in the presence of the target,and the positioning,robot assisted work,especially in the field of disaster rescue,military and other fields,sound source localization system has a unique advantage. The sound source localization robot system for research,design based on microphone array sound source localization robot system by four element planar microphone array,using the generalized cross correlation algorithm,to achieve the sound source localization. Experimental results show that the system has high positioning accuracy,with a high practical value.
