Abstract

The invention discloses a movement evaluation method of a virtual dance system. The method comprises the steps of firstly constructing a standard dance movement library and a virtual coach; secondly, capturing and digitizing the movements of dance students in real time, and positioning and aligning movement frames; finally, evaluating and scoring the dance movements. Through the adoption of the movement evaluation method of the virtual dance system, the body movements of the dance students can be recognized and captured in real time, automated evaluation is conducted on the learning situations of the students according to the standard movements of the coach movement library, and therefore the students can learn dance with professional guidance under the condition of self-learning.

Description

technical field [0001] The invention belongs to the technical field of computer applications, and in particular relates to a real-time, automatic and accurate comparison and evaluation method for student movements of a virtual dance system. Background technique [0002] The virtual dance system is a device for students to imitate the movements of a virtual coach for dance training. It generally includes a virtual coach system based on a standard movement library and a learning system for students to imitate dance movements. Whether the imitated dance movements are accurate, standard and consistent, etc. need to be compared and analyzed in combination with the characteristics of the movements and the performance of the device. The existing dance movement evaluation methods mainly include expert evaluation method, self-evaluation method and video tape analysis method. Among them, the expert evaluation method is to use the dance movement evaluation scale to score the dance mov...
