The movement in formation of players is a key factor to score a point in badminton doubles competition.
It is, however, difficult to find the problem on the movement of each player due to the complexity of the doubles rally strategy.
This research proposes a method for shot detection from competition videos toward a support system for coaching players for improving the rally strategy.
The proposed method solves the problem on shot detection from a competition video by solving the shortest path problem based on the shot likelihoods for players.
In more details, the proposed method detects and tracks the keypoints of each player in an input video, and then calculates the shot likelihood for each player in each video frame.
Based on the shot likelihoods, the global optimal solution, i.e. pairs of a shot timing (video frame) and a player are selected within a path problem under the constraints on the rules of badminton.
We conducted evaluation experiments with 19 doubles competition videos including 6,990 shots, and then confirmed that the F-measures of the proposed method were 0.892 in re-substitution validation, and 0.408 in leave-one-out validation, respectively. |
