Real-time dance movement generation method and system based on music rhythm

Abstract

The invention discloses a real-time dance movement generation method and system based on music rhythm. The method comprises the following steps: segmenting a dance movement sequence and a music sequence into dance movement fragments and music fragments; extracting motion features of the dance motion segments and music features of the music segments; carrying out rhythm feature matching on the dance movement segment and the music segment to obtain a dance movement segment matched with the rhythm of the music segment; analyzing the connectivity among the dance movement segments matched with therhythm of the music segment; performing intensity feature matching on each dance movement segment and the music segment which are determined to be connectable, and finally determining at least two dance movement segments matched with the music segment according to the intensity matching degree; and combining the finally determined dancing action segments into a dancing action sequence with naturaltransition. According to the invention, automatic arrangement of dancing is realized.

Description

technical field [0001] The invention relates to the technical field of motion simulation and game animation, in particular to a music rhythm-based real-time dance movement generation method and system. Background technique [0002] Dancing with music is a high-level art that combines auditory and visual enjoyment. Professional dancers will strictly control their dancing posture according to the melody, rhythm and intensity of the music, so as to convey the emotion of music more realistically through dance. How to perfectly match dance movements and music has become a difficult problem for dance choreography. Professional choreographers match different dance movements to each part of the music based on their own understanding of music emotions, combined with dance characteristics such as dance posture and dance step intensity. , For example, the movements with low dance intensity are matched with the soothing music prelude, and the movements with high dance intensity are mat...

AI Technical Summary

Problems solved by technology

This kind of dance arrangement relies too much on the experience of the choreographers, and inexperienced dancers cannot complete the choreography design by themselves

Moreover, this artificial choreography method is quite time-consuming and requires repeated choreography to finally determine the choreography plan. It is not suitable for some dance groups that lack choreography experience and mainly entertain
