Measurement of 3D Flight Trajectory of a Table Tennis Ball using Depth Camera and Estimation of Translational Velocity and Rotational Angular Velocity

Abstract

In this study, we developed a methodology to estimate the initial translational velocity and rotational angular velocity from the 3D trajectory of a table tennis ball. A depth camera was used to measure the 3D trajectory. The objective function is the mean square error between the measured 3D trajectory and the 3D trajectory generated from the motion model. A search experiment was conducted to determine whether the method proposed in this study could be estimated using actual measurement data. A particle swarm optimization method was used for the search.
