With the development of random image processing technology and in-depth learning, it is possible to recognize human movements, but it is difficult to recognize and evaluate dance movements automatically in artistic expression and emotional classification. Aiming at the problems of low efficiency, low accuracy, and unsatisfactory evaluation in dance motion recognition, this paper proposes a long short-term memory (LSTM) model based on deep learning to recognize dance motion and automatically generate corresponding features. This paper first introduces the related deep learning model recognition methods and describes the related research background. Secondly, the method of identifying dance movements is identified concretely, and the process of identifying concretely is given. Finally, through the comparison of different dance movements through experiments, it shows that there are obvious advantages in the accuracy of action recognition, error rate, similarity, and model evaluation method.
