METHOD OF GENERATING TRACKING INFORMATION FOR AUTOMATIC AIMING AND RELATED AUTOMATIC AIMING SYSTEM FOR THE VIDEO ACQUISITION OF SPORTS EVENTS, PARTICULARLY SOCCER MATCHES WITH 5, 7 OR 11 PLAYERS

摘要

A method of generating tracking information for automatic aiming for the video acquisition of sports events, particularly soccer matches with 5, 7 or 11 players, comprising the steps of: - generating (54), by means of a tracking unit (14a, 14b, 14c), a model of the background (101); - generating (56), by means of the tracking unit (14a, 14b, 14c), a grayscale mask of the moving objects (102); - filtering (58), by means of the tracking unit (14a, 14b, 14c), the grayscale mask of the moving objects (102), erasing the gray pixels, obtaining a mask of the moving objects without shadows (103); - filtering (60), by means of the tracking unit (14a, 14b, 14c), the mask of the moving objects without shadows (103), applying a graphic morphological erosion filter, obtaining a first mask of the moving objects (104) without shadows and without noise.
