摘要: In this paper, we investigate on the feasibility of multiple camera system for automatic offside detection. We propose six fixed cameras, properly placed two sides soccer field (three each side) to reduce perspective and occlusion errors. The images acquired by synchronized cameras are processed detect players' position ball in real-time; a view analysis is carried out evaluate event, considering all players field, determining who passed ball, if active condition occurred. whole has been validated using real-time during official matches, quantitative results accuracy were obtained comparing responses with ground truth data generated manually number extracted significant sequences.
