摘　　要：针对目前传统舞蹈教学过程中基本通过专业舞蹈教师对舞蹈动作的标准与否进行主观判断,缺少客观评价指标的现状,采用人体骨架模型分别对图像中国标舞学习者的舞蹈动作和标准舞蹈动作计算人体关键点坐标,再计算学习者舞蹈动作和标准舞蹈动作之间的相对偏移角度,根据得到的相对偏移角度设计评估学习者舞蹈动作是否标准的客观评估指标,通过该客观评估指标的量化数据判断学习者舞蹈动作的标准程度,并提出最终的舞蹈动作修正建议。在实拍舞蹈动作图像上的仿真结果表明,该方法所得客观评价结果与主观评价结果相一致,对于实时判断国标舞学习者动作标准程度有着良好的效果。In order to solve the current situation of subjective judgment on the standard of dance movements by professional dance teachers and the lack of objective quantitative evaluation indicators in the current traditional dance teaching process,the human pose estimate was used to calculate the coordinates of human body key points for the dance movements and standard dance movements of ballroom dance learners,and then calculate the relative offset angle between learner’s dance movements and standard dance movements,and an objective evaluation index was designed to evaluate whether learner’s dance movements were standard or not based on the obtained relative shift angle.Through the quantitative data of specific objective evaluation indicators,judge the standard degree of learner’s dance movements,and put forward the final suggestion for dance movement correction.The simulation results on the real dance action images show that the objective evaluation results obtained by this method are consistent with the subjective evaluation results,which has a good effect on judging the action standard degree of ballroom dance learners in real time.
