Abstract

A method performed on a computer system, for displaying video replay during a game of darts, comprising continually acquiring throughout the game, a video image of an oche from where a player throws darts towards a dartboard, detecting that a dart has been thrown by a player from the oche and is stationary on the dartboard, determining a trigger event based on the throw of the dart, automatically determining based on the trigger event whether to display a portion of the acquired video image captured between a first predetermined time before said detection and a second predetermined time after said detection, such that the portion of the acquired video image corresponds to the detected throw and displaying on a display the portion of the acquired video image.

Abstract

A method is disclosed for automatically scoring a game of darts. The method involves obtaining an image of a dartboard (2) using three cameras (10), detecting a visual disturbance in the image, and identifying a validly thrown dart if the visual disturbance includes a moving phase with a maximum temporal duration and successive images of the dartboard which exhibit differences. The visual disturbance should also include a stationary phase when the dart has been embedded in the dartboard (2). The method also includes calculating a score for the validly thrown dart based on its stationary position relative to the dartboard. A lighting system for a dartboard is also disclosed where a LED strip light (14) is provided around a circumference of the dartboard and three spotlights (8) are provided above the dartboard.
