Construction of Sports Training Evaluation System Based on Virtual Reality and Motion Capture

With the development of social economy and the improvement of living standard, people begin to seek more realistic simulation experience. As a new multi-channel information fusion technology, virtual reality (VR) is bringing people a brand-new human-computer interaction experience. The existing motion posture capture system needs to wear additional auxiliary equipment for the experimenter, which is inconvenient to operate; And some equipment can’t be applied to outdoor scenes, so the scope of use is limited; The method based on monocular estimation of human body’s three-dimensional posture has low accuracy and poor robustness. Virtual motion based on motion capture verifies the isomorphic motion between life ontology and virtual life, which provides unprecedented possibility for exploring and expressing the essence of life. This paper introduces VR technology and motion capture technology into the protection field of kungfu culture, develops a virtual system that gives consideration to both appreciation and learning, and solves the problem of protection and inheritance. The appreciation system tracks and identifies the user’s body through motion capture technology, uses VR engine to realize motion data driven character model, and realizes the visualization of characters in virtual environment and quantitative evaluation of results.
