Abstract

The present invention discloses a virtual dance teaching method and system. The method comprises the steps of: performing choreographer professional action capture; performing construction of an action library; according to the action library, and driving a coach model to perform dance teaching. The action of a professional choreographer is captured to determine the standard action of the professional dance, the standard action is subjected to skeleton alignment to perform coding of an XML mode, and the coach action library is constructed after the basic action is determined through optimization, a virtual dance role is constructed to perform sampling of the choreographers and students to perform three-dimensional model geometric construction, the action data of the standard action libraryis employed to drive the coach model to drive a student model in real time through Kinect and perform visualization showing of the dance action for the students to study, and finally, the dance action is evaluated through an evaluation algorithm (cosine feature value Euclidean distance) to allow the students to perform introspection. The virtual dance teaching method and system are simple and effective for dance teaching and feedback, and save the cost.

Description

technical field [0001] The invention belongs to the field of computer application technology, and in particular relates to a virtual dance teaching method and system. Background technique [0002] The virtual dance teaching system is a device that shows standard dance movements for learners to help students perform dance training. With the continuous development of somatosensory technology, virtual dance learning has become easier and more convenient, especially with the emergence of Kinect somatosensory equipment, many somatosensory dance games and teaching applications have appeared on the market, and the key to virtual dance construction is standard dance movements The capture, optimization and construction of motion library. [0003] Currently popular motion capture methods mainly include motion capture based on optical motion capture systems and motion recognition and capture based on Kinect somatosensory technology. Optical motion capture systems require users to wear...
