摘要
本文介绍了利用快速相机测量吉他弦振动的硬件和软件解决方案。本文提出了用于 3D 图像采集的正交设置,每秒可捕捉数千帧图像。论文中开发并描述了专用的图像处理算法,旨在跟踪琴弦上某些选定点的移动。快速准确的跟踪结果提供了详细的振动信息,并将其转化为声音样本。为了将捕捉到的琴弦振动与使用麦克风录制的声音进行比较,本文介绍了声音处理方法。报告还包括对所获结果的分析、结论和未来工作计划。
Application of fast cameras to string vibrations recording
A hardware and software solution for guitar string vibration measurement by fast cameras is described. Orthogonal setup for 3D image acquisition is proposed capable to capture several thousand image frames per second. Dedicated image processing algorithm was developed and described in the paper, aimed at tracking the movement of some selected points along the string. Fast and accurate tracking results provided a detailed information about vibrations, that was transformed into sound samples. Described sound processing methods were applied in order to enable a comparison of captured string vibrations with the sound recorded using a microphone. Analysis of obtained results, conclusions, and future work plans are included.
