摘要
基于图像的智能视频监控系统由于视角有限,当目标不在摄像头视场范围时,易出现监控盲区,为了解决该难题,利用声源定位的优点,提出一种具有听觉功能的智能视频监控系统。首先采集传声器线性阵列,采用时延估计技术对声源进行定位,然后根据声源位置驱动摄像头,使其转动到声源位置并采集视频信息,最后采用图像检测程序对目标进行实时定位和跟踪,并通过仿真测试验证该系统的可行性,结果表明,该系统具有较好的定位和跟踪精度。
Intelligent video monitoring system based on image is limited by view angle,when the target is not in the view range of camera,monitoring blind area is easy occurred. In order to solve the problem,an intelligent video monitoring system is proposed based on voice localization. Firstly,micro- phone linear array is acquired, and the position of the sound source is location by the time delay, and then cameras are turning to the sound source position by the sound source message and collect video information. Finally, the target is real-time positioned and tracked by image detection, and the simulation experiments are carried out to test the feasibility of the system. The results show that the proposed system has high location precision.
