    Abstract: A golf training and game system is situated in a golf playing facility with tee and target areas. At each target area an overview video camera captures an image of the target area when a golf ball is hit from a tee. A target measuring system performs image improvement methods on the captured image, detects possible balls, and calculates coarse real coordinates for the possible balls. A memory stores real coordinates for previously-identified balls. Coordinates for possible balls and identified balls are compared to determine new balls to be identified. New ball coordinates are used to position, zoom and focus a zoom video camera and capture a fine image. The target measuring system performs image improvement methods and pattern recognition on the fine image to identify the new balls and get fine real coordinates. Information sent to a tee terminal gives feedback to the players.
