[0065] Please refer to figure 1 As shown, the embodiment of the present invention provides a method for automatically playing a stringed instrument, specifically a method for automatically playing a guitar score, including:
[0066] S11. Generate a machine-visualized score image according to the score image. The machine-visualized score image includes a time value area and a note matrix area, and each row in the note matrix area corresponds to each string of the stringed instrument to be played.
[0067] In this embodiment, the row where the note value of each column of the note matrix area corresponds to each string of the stringed instrument, and the note value of each column of the note matrix area corresponds to each fret of each string of the stringed instrument.
[0068] S12. Obtain the row where the note value of each column in the note matrix area is located and the note duration corresponding to each column, and determine the string picking rule of the string picking ...

[0072] Please refer to Figure 2 to Figure 11 As shown, the embodiment of the present invention provides another automatic playing method of a stringed instrument: the playing method includes:
[0073] S201, binarize the music score image and then project and stack it on the y-axis to generate a music score feature image;
[0074] S202. Determine a first characteristic linear image in the musical score characteristic image;
[0075] S203, according to the thickness, x-axis length and y-axis interval of each line segment in the first characteristic linear image, determine the time value image area and the musical note image area in the music score image;
[0076] Exemplarily, in this step, the spectral line area can be determined first through the y-axis direction interval of each horizontal line segment, and then the time-decreasing line / time-increasing line can be determined according to the thickness of the line segment and the length of the x-axis (in this embodiment, the ...

Abstract
The invention discloses an automatic playing method and device of a stringed musical instrument. The method comprises the steps of generating a machine-visualized music score image according to a music score image, wherein the machine-visualized music score image comprises a time value region and a note matrix region, and each row of the note matrix region corresponds to each string of a to-be-played stringed musical instrument, obtaining the row where the note numerical value of each column of the note matrix region is located and the note time value corresponding to each column, determininga string plucking rule of a string plucking mechanism of the playing device, and obtaining the note numerical value of each column of the note matrix region, the row where the note numerical value islocated and the note time value corresponding to each column, and determining the string pressing rule of the string pressing mechanism of the playing device. Automatic identification and automatic playing of the music score by a machine are realized, complex operation of manually inputting music score data is avoided, and time and manpower are saved; the automation degree of stringed musical instrument playing is improved, and the consistency and reliability of stringed musical instrument playing are guaranteed.
Description
technical field [0001] The invention relates to the field of automation, in particular to an automatic playing method for a stringed instrument. Background technique [0002] Existing automatic playing robots need to manually input the score data, and then the robot analyzes and plays the manually entered score data. [0003] In this process, the operation of entering the score is relatively complicated, time-consuming and labor-intensive. In addition, there is no better automatic playing method for stringed instruments that need to be plucked and pressed at the same time, and the degree of automation of stringed instruments is relatively low. Contents of the invention [0004] In order to overcome the problems in the prior art that there is no better automatic playing method with a low degree of automation and simultaneously realize the operations of picking and pressing strings, an embodiment of the present invention provides an automatic playing method for a stringed i...
