Badminton track analysis method and system based on immersion

The invention relates to a badminton track analysis method and system based on immersion, and belongs to the technical field of visualization and visual analysis. The method comprises the following steps: 1) a user wears a virtual reality device including a head-mounted display and a handle, and selects a to-be-analyzed ball hitting technology; 2) all tracks belonging to the selected ball hittingtechnology are clustered to form a plurality of class clusters; 3) the user performs trajectory overview on a plurality of class clusters of the selected ball hitting technology, selects a certain class cluster, and removes outlier trajectories or trajectories which are not expected to be analyzed in the class cluster to obtain a to-be-analyzed class cluster; and 4) the relationship between the attribute of the key point of each trajectory k in the same to-be-analyzed class cluster and the statistical characteristics is explored, or attributes between the trajectories in the two classes of clusters are compared. 本发明涉及
