This Research focuses on the intelligent tennis practicing device design based on stochastic differential equations. By constructing the Fokker-Planck equation, we aim to test the accuracy of the algorithm and improve the precision of data feedback. We use the intelligent tennis practicing device of the Hong Kong Swallowsing Sports Technology Co., LTD., as the research object. By reading the data of simulated physical tennis through sensors, such as moving acceleration, angular velocity, and tennis rotation speed, we perform data selection and calculation to generate the virtual three-dimensio...
