抄録
内容記述 We propose a real-time measuring method of both the translational/rotational velocities of a flying ball using two high speed cameras. The rotational velocity is estimated by the kinematics which relates the velocity to the position variation of the centroid of a feature area marked on the ball. The position variation is calculated by the correlation between two images with respect to the translational displacement in the images. The corresponding 3D position of the feature area is necessary for the estimation by the kinematics. It is calculated by the centroids of all the feature areas on the ball in the left and right images with the assumption where the centroids coincide with each other in the 3D space. The proposed method is verified with respect to some configurations of the cameras and texture patterns of the feature areas by numerical simulations. The effectiveness of the method is verified by experiments.
