Key identification method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention discloses a key identification method and device, electronic equipment and a storage medium, relates to the technical field of music education, and can conveniently andeffectively perform key identification. The method comprises the steps of: collecting a first keyboard image of a target musical instrument, and arranging black keys and white keys on a keyboard of the target musical instrument; inputting the first keyboard image into a preset image recognition model to determine the contour of each black key in the first keyboard image; and determining a piano key range corresponding to each octave in the first keyboard image and the outline of each white key in each octave according to the outline of the black key and the distance between the adjacent blackkeys. The key identification method and device, the electronic equipment and the storage medium can be used in the field of music education.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a keyboard recognition method, device, electronic equipment and storage medium. Background technique [0002] In the field of piano education, in order to monitor whether the user is playing accurately and fingering is correct, it is often necessary to detect the keys of the piano. [0003] At present, many traditional piano key detection schemes are based on photoelectric sensors and multi-channel single-chip microcomputer technology, but this detection scheme has the following disadvantages: it occupies the space of the keys and affects the playing; the structure is fixed and unstable, and it is easy to generate noise and interfere with the sound of the piano; , affect the appearance; the structure is complicated; the circuit is complicated and the cost is high. [0004] In addition, there are some piano key detection schemes that draw a fixed piano key position in the camer...

Problems solved by technology

[0003] At present, many traditional piano key detection schemes are based on photoelectric sensors and multi-channel single-chip microcomputer technology, but this detection scheme has the following disadvantages: it occupies the space of the keys and affects the playing; the structure is fixed and unstable, and it is easy to generate noise and interfere with the sound of the piano; , affect the appearance; complex structure; complex circuit, high cost, etc.

However, this will not only consume the player's precious time to adjust the camera, but also affect the original aesthetics of the piano itself.

[0005] For how to carry out key identification conveniently and effectively, there is no effective solution in related fields
