Research on the Application of Information Fusion Technology in the Choreography of Hezhen Dance

The difficulty of creating and choreographing group dances lies in the need for dozens or even hundreds of actors and choreographers to work together to complete the workload and its complexity. A computer-aided dance creation and choreography technology based on information fusion technology is proposed in this paper as a solution to this problem. The movement path is extracted from the movement trajectory of the character’s root joints using information fusion technology. The interactive interface is used to create the target path, which is then mapped to the dance movement. The actor’s dance is freely edited based on the characteristics of their body’s movement posture. To confirm the effectiveness of the method, the Herzhe ‘Fish Eagle Dance’ dance movements were tested with dance creation and choreography technology. The results show that the spatiality intensity of the first and second movement segments was found to be 0.1618 and 0.4555, respectively, during the choreography process. The standard and measured values of the movement angle of the left arm joints appeared to have the maximum difference value of 0.19771 between 9~10 s. The choreographers can use these resultant parameters to optimize the cumbersome, repetitive rehearsal process by providing data references.
