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.
