Tujia brocade is a typical brocade of ethnic groups in China and also known as "Xilankapu", or "Knitting Floral Bedspread". It was listed in the directory of National Intangible Heritages of China in 2006. However, due to the impact of the way of Tujia brocade craft inheritance and other factors, Tujia brocade craft is increasingly declining. So it is urgent to strengthen the digital protection of Tujia brocade, this paper tries to carry out discussion and study of the key movements of Tujia brocade craft. And it puts forward a new method in intangible culture heritage protection based on unmarked motion capture technique. It captures the key actions of twelve processes of Tujia brocade craft combined with Kinect and Leap Motion and establishes a motion data set of Tujia brocade. In addition, virtual representation of Tujia brocade craft is realized by three-dimensional animation technology. Thus the research causes quite great practical effect on digital protection of Tujia brocade.
