Title
(EN) BALL TRAJECTORY TRACKING
(FR) SUIVI DE TRAJECTOIRE DE BALLE
Abstract
(EN)
A method of ball trajectory tracking, the method comprising computer executable steps of: receiving a plurality of training frames, each one of the training frames showing a trajectory of a ball as a series of one or more elements, using the received training frames, training a first neuronal network to locate a trajectory of a ball in a frame, receiving a second frame, and using the first neuronal network, locating a trajectory of a ball in the second frame, the trajectory being shown in the second frame as a series of images of the ball having the located trajectory.
(FR)
La présente invention concerne un procédé de suivi de trajectoire de balle, le procédé comprenant des étapes exécutables par ordinateur consistant : à recevoir une pluralité de trames d'apprentissage, chacune des trames d'apprentissage présentant une trajectoire d'une balle comme une série d'un ou plusieurs éléments, à l'aide des trames d'apprentissage reçues, à entraîner un premier réseau neuronal pour localiser une trajectoire d'une balle dans une trame, à recevoir une seconde trame, et à utiliser le premier réseau neuronal, à localiser une trajectoire d'une balle dans la seconde trame, la trajectoire étant représentée dans la seconde trame sous la forme d'une série d'images de la balle ayant la trajectoire localisée.
