Abstract:In the teaching of college dance Liyuan Opera Kebu, Liyuan opera Kebu teaching has always been considered as an important part of college dance teaching, with non-stop use and practice. However, the only deficiency is the failure of integrating Liyuan Opera Kebu dance teaching into college dance teaching. Therefore, based on the subject, this paper analyses the problems in college dance Liyuan Opera Kebu teaching, and further discusses the countermeasures and suggestions in the teaching of Liyuan Opera Kebu dance in colleges, so as to promote its normative progress, and promote the dance teaching in colleges to achieve greater success.

In order to explore the problem of dance somersault gesture recognition, a kind of dance somersault gesture recognition based on multi-scale depth feature fusion is proposed. Methods Through the information recommendation of key technical problems and solutions based on multi-scale depth feature fusion, the research of dance somersault gesture recognition was explored. The research shows that the efficiency of dance somersault gesture recognition based on multi-scale depth feature fusion is about 4.6% higher than that of traditional methods. The acquisition of main video information has always been inclined to obtain video key frames. However, in the face of videos with strong continuity and low repetition between human posture sequences in various movements, only key frames can't represent all the effective information of the videos. Most algorithms excessively pursue the differences between action categories, thus ignoring the degree of "cohesion" between simple actions within actions.

China has continuously pursued culture innovation and culture construction in recent years. Dance culture also belongs to a part of culture construction. At present, certain gap in culture construction still exists between China and Western countries. An obvious gap is in dance teaching technology. The comparison of the application status of virtual reality technology in dance teaching at home and abroad is conducted in this paper. Then, the design requirements of virtual reality technology in dance teaching are expounded. Finally, relevant suggestions are proposed to enlighten the peers.
