Three-dimensional Position Information Tracking Algorithm for Virtual Teaching Experiments

Aiming at the problem of the difficulty of real-time accurate sensing and positioning of virtual objects in virtual experiments in middle schools, this paper designs a real-time acquisition algorithm of three-dimensional position information of virtual objects based on monocular vision. The designed target object binding can only perceive objects in a virtual scene in real time and accurately calculate its three-dimensional position information under an ordinary monocular camera. Finally, it is verified on the experimental teaching platform of fusion of reality and reality, which significantly reduces The difficulties in the interaction process enhance the user's sense of interaction and experience.
