Abstract:This paper mainly analyzed the application of inertial sensors in basketball posture analysis. The data of 20 basketball players in different postures were collected by MEMS inertial sensors. The mean, variance, and skewness were taken as features to compare the performance of C4.5, random forest (RF), k-nearest neighbor (KNN), and support vector machine (SVM) algorithms in analyzing posture data. It was found that the classification accuracy of the KNN algorithm was around 90%, and the classification accuracy… Show more
