The ground truth we used in this research is achieved by manually drawing the strike zone following baseball rules in the Prepare frame. Then, this manually drawn strike zone was compared with the strike zone computed using the Yolo-Pose and the electronic strike zones to calculate the IoU. The electronic strike zones used nowadays rely on synchronized images captured by two high-speed cameras, which are used to calculate the 3D coordinates of the strike zones through triangulation techniques. The compared result is shown in this table. We can see that Our Yolo-Pose strike zone is more accurate than the electronic strike zone used nowadays. Yolo-Pose strike zone's IoU is zero point eight five four one, and the electronic strike zone used nowadays is zero point seven four seven three. Yolo-Pose has a fourteenth point two nine percent improvement. |
