| 中文摘要 | 基于双目视觉技术和阵列测量方法设计实现了一种声学摄像机,可以实现声场的动态视频可视化。基于波束成型原理,利用十字阵列实现空间声场的动态测量,构造空间指定位置的二维声场云图。利用双目立体视觉技术,实现被测空间的空间位置定位,与通过声阵列方法获得的声场图像建立统一的时间空间坐标系,实现声场图像和视频图像的融合,实现空间声场的视频可视化,达到准确、直观地进行声源定位和显示的目的。; Based on the technique of binocular vision and the measurement by microphone array,an acoustic vidicon system was designed and realized in order to make the visibility of dynamic sound field of moving sound source by video.Based on the principle of beamforming,a cross array was utilized to measure the dynamic sound field,and constructed the 2-D sound field contour map at specified spatial positions.Using the technique of binocular vision to locate the spatial position and establish uniform time and spatial coordinate systems with the image of sound field acquired by microphone array,combine the two kinds of images,thus the visibility of spatial sound field was made by video,and the sound source could be located and displayed accurately and objectively.; 国家自然科学基金(NSFC,50605038)资助项目 |
