Abstract
Under the premise of fully respecting Technical Leaflet T3 developed by the International Table Tennis Federation (ITTF), this paper proposes an effective method for testing the veer degree of the table tennis ball based on airflow suspension and machine vision. By sequentially capturing the images of the ball in the stable state of spinning and suspension, a set of fitting circle centres from different circular sections can be obtained by circle fitting through the least square method. The minimum circumscribed circle (MCC) diameter of these centres is served as a basic parameter to evaluate the veer degree of the ball. Experimental results show that this diameter can effectively reflect the veer degree of the ball. The method proposed in this paper can provide a technical basis for the veer online testing of the table tennis ball.关键词
