Abstract
A video acoustical method determines an impact point of a thrown body on a landing area, in particular for athletics throws disciplines, the body describing a trajectory in the air from a take-off area towards the landing area, the impact point being defined by the body hitting on the landing area. The method includes acquiring video exposures of the body impact on the landing area to a frame rate, each exposure showing one position of the body; calculating the body trajectory during at least the body impact on the landing area with the video exposures analysis; detecting an acoustical impact time due to the body hitting on the landing area; and determining the body impact point on the calculated trajectory with the detected acoustical impact time. A video acoustical system can determine an impact point of a thrown body on a landing area.
