A Scoring Method Based on the Evenness of the Player's Limb Rhythm

Abstract

The invention discloses a scoring method based on uniformity coefficient of rhythms of limbs of a player. The scoring method comprises the following steps of acquiring three-axis accelerated speed data of a player within a sampling period by using a three-axis accelerated speed sensor attached to the limbs of the player; finding out an axis with the maximum peak value and sampling sequence numbers k corresponding to all wave crest points of accelerated speed data of the axis; sequentially arranging the sampling sequence numbers k from small to large so as to form a sequence; performing first-order linear fitting on the sequence by using a least square method and calculating variance of the sequence; performing game scoring according to the variance of the sequence; repeating the above steps to calculate scores in different sampling period time buckets in a whole game process; and calculating an average value, which is the final score of the player, of the cores. After the three-axis accelerated speed sensor and simple control circuits are arranged in music equipment, a scoring problem of the player is solved. Moreover, the scoring method is accurate and reliable.

Description

technical field [0001] The invention belongs to the field of music games, and in particular relates to a scoring method according to the uniformity of body rhythms of players. Background technique [0002] With the continuous development of electronic technology, consumer electronic products are widely used in life. Listening to music has become an indispensable part of people's daily life. People enjoy music feasts in more and more diverse forms. Now people are not only satisfied with wearing headphones to listen to professional singers, but also hope to interact with music more actively. Since the 1980s, karaoke has developed rapidly in China. People can sing along with music accompaniment, and can also increase the fun of singing by scoring the singing level. Music includes elements such as timbre, pitch, loudness, and rhythm. Karaoke scoring usually uses a microphone to record singers. After the singing is over, the singer's intonation, rhythm, and other elements are c...
