Embodiment Construction

[0039] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] The schematic diagram of the overall structure of the detection device corresponding to the method for detecting the timbre of guitar strings based on machine vision in this embodiment is as follows figure 1 shown. The device includes a gripping end 1, a saddle end 2, a saddle end 3 and a stretching end 4. The gripping end 1, the saddle end 2, the saddle end 3 and the stretching end 4 are four points and one line, and the saddle end The end 2 and the saddle end 3 are arranged in parallel, perpendicular to the straight line direction from the holding end 1 to the stretching end 4, and the bridge end 2 moves along the straight line direction from the holding end 1 to the stretching end 4; the string to be tested 5 is fixed at the holding end 1, passing through the bridge end 2, the saddle end 3 to the stretching end 4 in seq...

Abstract

The invention discloses a guitar string timbre detection method based on machine vision and belongs to the field of musical instruments, mechanical equipment and precise instruments. The detection method comprises steps as follows: firstly, adjusting the position of a saddle end (2), adjusting the pitch of a to-be-detected string (5), then acquiring an oscillating image and obtaining an oscillating function, and finally, comparing the oscillating function with an evaluation function obtained according to the amplitude in the position where the amplitude of the to-be-detected string (5) is maximum to obtain the timbre detection result. The technical purpose of judgment of the string timbre through detection of the oscillating track of the string can be achieved with the method.

Description

technical field [0001] A machine vision-based guitar string timbre detection method belongs to the fields of musical instruments, mechanical equipment and precision instruments. Background technique [0002] The guitar, also known as the violin, is a plucked string instrument that is often regarded as the main instrument in pop music, rock music, blues, folk songs, and flamenco. [0003] Since the guitar produces sound by the vibration of the strings, the sound of the guitar depends first on whether the vibration trajectory of the strings is standard. Based on the above analysis, the quality of the guitar tone can be judged by detecting the vibration trajectory of the strings. [0004] Unfortunately, there is no detection device and method for judging the timbre of the strings by detecting the vibration trajectory of the guitar strings at this stage. Contents of the invention [0005] In order to achieve the purpose of judging the quality of the guitar timbre by detectin...
