| This paper mainly focuses on the analysis of virtual teaching technology of table tennis.Firstly,it analyzes the significance and background of this research,the research status at home and abroad,the basic understanding of the research status of virtual teaching technology of table tennis,and determines the research ideas;secondly,it analyzes the virtual reality technology,robot technology and other related technical theories to lay a theoretical foundation for this research.In the ode technology,the simulation platform is built for table tennis teaching,which focuses on the dynamics of the ball,racket,table and net modeling analysis,and completes the performance design of the platform.After the completion of the system design,in order to have a basic understanding of its application performance,simulation analysis is carried out for some software,including static test and simulation test.In the research process,the rotating ball is taken as the research focus,and the trajectory of different rotating balls is simulated and analyzed.The simulation results show that the trajectory of the non rotating ball is: the incident angle is smaller than the bounce angle;the running speed after rebound is smaller than the original speed;the running track of the rotating ball is: with the increase of the rotating speed,the movement deviation track of table tennis becomes more and more dense,that is,the influence of rotation speed is obviously reduced.If the linear velocity is kept constant,the Magnus force will be stable gradually when the speed reaches a certain value,which is in accordance with the law of Magnus force.Through the analysis of simulation experiment,it is found that the kinematics model and simulation environment can realize the accurate simulation and analysis of different table tennis trajectory.The experimental results show that the system is operable.Finally,the application analysis of virtual teaching technology of table tennis is carried out to complete the action of virtual human,the modeling design of virtual table and the simulation of running track of virtual ball,which provides real experience of table tennis competition for participants in virtual environment.The application of this technology in teaching can be based on the latest virtual reality technology,6-DOF sensing technology,three-dimensional imaging technology,etc.for students,it can obtain real confrontation situation experience,and can obtain virtual competitive feeling with high experience in the process of competition,so as to improve their table tennis skills;for teachers,it not only helps to reduce the workload At the same time,it can also achieve a comprehensive grasp of students’ competitive performance,and then according to the actual situation of students to develop corresponding teaching programs,improve the quality of teaching.After being applied in practical teaching,it has been warmly welcomed by teachers and students,and the application effect is remarkable.After the completion of the whole work process,the application of the experiment is analyzed,and it is confirmed that this experiment has a certain application value. |
