仿照生物的趋声性,可以实现摄像头追踪拍摄一个不在其视场范围内的声源;依据图像处理技术,可以精确定位在摄像头视场内的声源。将这两种技术结合起来,建立了一套实验系统。从利用声源发出的声音信号传输到两个分开一定距离的声音探测器上的时间差初步定位声源,再利用声源的运动规律使用图像处理技术识别并精确定位声源,通过系统与PC机间的实时通信和回转部件带动声音探测器和摄像头一起做精确灵活的转动,摄像头最终对准了声源。实现了基于声音的跟踪摄像过程。
Following the trend of creatures, you can realize that the camera track and capture a sound source that is out of its field of view. Based on the image processing technology, you can precisely locate the sound source within the camera’s field of view. Combining these two technologies, a set of experimental systems was established. From the use of the sound source to send the sound signal transmitted to the two sound detectors at a certain distance from the initial positioning of the sound source, and then use the sound source movement of the use of image processing technology to identify and accurately locate the sound source, through the system and the PC Between the real-time communication and rotary components to drive the sound detector and the camera together to do precise and flexible rotation, the camera eventually aimed at the sound source. Realize the sound-based tracking camera process.
