Embodiment 1

[0045] figure 1 It is a schematic flow chart of a music score recognition method provided by Embodiment 1 of the present invention. This embodiment is applicable to any situation where a music score needs to be created on a touch screen. It is realized by hardware and can generally be integrated in touch-enabled devices. Specifically include the following steps:

[0046] S110. Receive the input track graphic of the note on the pre-displayed stave input interface.

[0047] Among them, the stave notation is the general notation method in the world at present. It records music by marking notes of different time values ​​and other marks on five equidistant parallel horizontal lines. The five lines from bottom to top in the stave are the first line, the second line, the third line, the fourth line and the fifth line. The place between the lines is called the room, and from bottom to top it is the first room, the second room, the third room and the fourth room. If the lines and...

Embodiment 2

[0057] Figure 4 It is a schematic flowchart of a music score recognition method provided by Embodiment 2 of the present invention. This embodiment is a further description of embodiment one. In this embodiment, the shape of the corresponding musical note and the position of the musical note in the stave are identified according to the input trajectory graphics, including: confirming the boundary rectangle of the input trajectory graphics; All the pixels in the preset area with the center as the center are the pixels in the input trajectory graphics, then the shape of the note is judged to be solid; otherwise, the shape of the note is judged to be hollow; if the center of the bounding rectangle is closest to the center of the bounding rectangle If the distance of a line is less than the preset threshold, it is determined that the position of the note is on the line closest to the center of the bounding rectangle, otherwise it is determined that the position of the note is betw...

Embodiment 3

[0073] Figure 7 It is a schematic flowchart of a music score recognition method provided by Embodiment 3 of the present invention. This embodiment is a further description of the above embodiment. In this embodiment, after recognizing the shape of the corresponding musical note and the position of the musical note in the stave according to the input trajectory graphic, it also includes: displaying a standard musical note at the position of the musical note.

[0074] Correspondingly, the method in this embodiment specifically includes:

[0075] S310. Receive the input trajectory graphics of musical notes on the pre-displayed stave input interface;

[0076] S320. Identify the shape of the corresponding musical note and the position of the musical note in the stave according to the input trajectory graphics;

[0077] S330, displaying standard musical notes at the position of the musical notes.

[0078] The standard note format is that the note head is elliptical, and the left...

Abstract

The embodiments of the invention disclose a music score identifying method and apparatus. The method includes the following steps: receiving an input locus figure of a note on a pre-displayed music notation; based on the input locus figure, identifying the shape of the corresponding note and the position of the note in the music notation. According to the embodiments of the invention, the technical solution enables instant and direct music score producing in a touch screen, increases fun in music learning and teaching efficiency, and makes teaching more flexible.

Description

technical field [0001] Embodiments of the present invention relate to human-computer interaction technology, and in particular to a music score recognition method and device. Background technique [0002] With the continuous improvement of people's living standards, more and more people are devoted to the study of music. Wherein, stave notation is the general notation method in the world at present, and it is a kind of method of recording music with notes of different time values ​​and other marks on 5 equidistant parallel horizontal lines. [0003] At present, when people use touch devices for music teaching, they generally need to make and save music scores in advance, and then load the music scores to playback devices or playback software for playback, so as to conduct teaching according to the produced music scores. [0004] However, in the process of learning music, only the music scores made in advance can only be played, which greatly reduces the learning interest an...
