Piano practice error correction method based on image recognition processing

Abstract

The invention discloses a piano practice error correction method based on image recognition processing and relates to the technical field of intelligent teaching. The method comprises the following steps of: step 1, intercepting and shooting images of each frame of finger joints and piano keys from piano teaching videos, and preprocessing each frame of images; step 2, identifying and calculating by using the preprocessed images, outputting piano keys and human body finger joints and position coordinates of the piano keys and the human body finger joints contained in the images, and sequentially connecting the human body finger joints and the piano keys to form a standard finger model diagram and a standard key sequence model diagram. According to the method, the piano practices and the teaching videos are compared and analyzed through image recognition, the practice skill, the key position and the sequence are corrected automatically, errors of each step of a trainer can be found out accurately, guidance reference is provided, the intelligent teaching without human monitoring is achieved, and the difficulty of piano practice can be reduced.

Description

technical field [0001] The invention belongs to the technical field of intelligent teaching, and in particular relates to an error correction method for piano practice based on image recognition processing. Background technique [0002] The correct piano hand shape is an important part of piano practice. In piano playing, the five fingers need to be separated, the palm is arched, and the whole hand forms a semicircle. For beginners, it is difficult to separate the five fingers. In addition, when children practice the piano, due to their weak hand strength, the five fingers often have problems of insufficient strength. At the same time, some children may have sunken palm joints, resulting in improper hand shape and affecting playing. [0003] At present, in the current piano training and education process, it is difficult for beginners to maintain a correct posture for the shape of their hands and fingers, especially for younger students, it is difficult to stand up at the en...

In addition, when children practice the piano, due to their weak hand strength, the five fingers often have insufficient strength. At the same time, some children may have sunken palm joints, resulting in improper hand shape and affecting playing

[0003] At present, in the current piano training and education process, it is difficult for beginners to maintain a correct posture for the shape of their hands and fingers, especially for younger students, it is difficult to stand up at the end of the finger joints. The habit of playing the piano is a great hindrance to the improvement of the performance level, and often press the wrong piano keys without knowing it, resulting in the formation of wrong exercises, with half the effort

The current solution can only rely on the teacher's constant reminders, and rely on the teacher to supervise whether there is a wrong key, and correct the error. Since the teacher cannot be around at any time, it is difficult for beginners to learn and practice piano. , prone to disgust
