1. Each single video clip is scored separately, with a total score of 1 point per video clip. First, the number of shots in the rally video is validated, and each row of the CSV file is considered as one shot. 

• If the predicted number of shots is different from the ground truth, the question will be scored as 0 points.

• If the number of shots is the same, 0.1 points will be awarded, and proceed to the next stage to compare the content of the columns, with the highest score for column content being 0.9 points.

2. If the number of shots is correct, compare each shot in sequence, with each shot scored according to the total score of the columns, and the average of each shot's score as the score for content. First, the HitFrame column is validated. If the prediction error is greater than 2 frames compared to the true value, the shot will get 0 points in content and proceed to the next shot for scoring; if the prediction error is not greater than 2 frames, 0.1 points will be given, and proceed to compare other columns in the same shot.

• Hitter: 0.1 points if correct, 0 points otherwise.

• BallHeight: 0.1 points if correct, 0 points otherwise.

• Landing: If the prediction error is not greater than 6 pixels in the Euclidean distance, it is considered correct and is awarded 0.1 points; otherwise, 0 points.

• HitterLocation: If the prediction error is not greater than 10 pixels in the Euclidean distance, it is considered correct with 0.05 points, otherwise 0 points.

• DefenderLocation: If the prediction error is not greater than 10 pixels in the Euclidean distance, it is considered correct with 0.05 points, otherwise 0 points.

• Backhand: 0.05 points if correct, 0 points otherwise.

• RoundHead: 0.05 points if correct, 0 points otherwise.

• BallType: 0.2 points if correct, 0 points otherwise.

• Winner: 0.1 points if correct, 0 points otherwise. (Note: If it is not the last shot but is filled in, it will be considered incorrect.)

This dataset consists of international competition videos organized by the Badminton World Federation (BWF). The recorded matches are shot from the back of and above the players. Each video will record a rally from the serve to the dead ball stage and the marked file after the shot mark, with an mp4 encoding and a CSV format for the marked file, and a frame rate of 30 FPS and a resolution of 1280*720. The dataset includes 13 annotation fields. The following are the descriptions of each annotation field:

• VideoName: The file name of each rally video

• HitFrame: The moment of the shot in the rally, in frames

• Hitter: The player hitting the ball, marked with A/B

• A: Sited farther from the camera

• B: Sited closer to the camera

• BallHeight: The height of the hitting point, marked by 1/2

• 1: The hitting point is above the net

• 2: The hitting point is below the net

• RoundHead: Whether the player has a round-head hitting action, marked by 1/2

• 1: Round-head hitting

• 2: No round-head hitting

• Backhand: Whether the player's hitting action is backhand, marked by 1/2

  • • 1: Backhand hitting

    • 2: Not backhand hitting

• LandingX/LandingY: The projection on the court plane of the shuttlecock at the end of the trajectory either hit by the opponent or touch the ground, in pixels

• HitterLocationX/HitterLocationY: The location of the striking player, taking the toe of the habit foot as the coordinates in the picture, in pixels. If there is a jump, the coordinates projected onto the court plane are the answer

• DefenderLocationX/DefenderLocationY: The location of the defending player, similar to the location of the hitting player

• BallType: Nine types of balls, marked by 1~9. 1~2 are the types of serves, used only for serving (or first shot); 3~9 are the types of returns, used for subsequent shots

• 1: Short serve

• 2: Long serve

• 3: Clear

• 4: Drive

• 5: Smash

• 6: Net shot

• 7: Drop shot

• 8: Lift

• 9: Push shot

• Winner: Winning and losing points, divided into three categories, marked with A/B/X. Only the last shot of each rally video can be scored, and the rest are marked with X

• A: Score by upper half-court player

• B: Score by lower half-court player

• X: No score
