Abstract
A device for automatic determination of plane dart, having in the lower part of the target (Z) at least a light source (4), and on the other side of the target (Z) a light sensor (S) facing the light source (4), when the dart (P) tip reaching the target (Z) blocks the sensor (4), the sensor would emit a signal, and a plurality of processors (25) for calculation of the location of the dart (P) on the target (Z) based on the signal emitted by the sensor (S), including the device: a fixed light source (4, L) having a strip lighting area (5), for emission of light passing over the target (Z) and crossing the dart (P) tip on the target (Z) on a target (Z) surface in parallel; a plurality of angle sensors (S), for fixing at least on one of the points (A, B, C) on the linear bottom line under the target (Z), for emission of measurement signals corresponding to the angles forming straight lines (a, B,) from the bottom line and the dart (P) to the bottom line (A, B, C); a processor (25), for calculation of position of the dart (P) on the target (Z) based on the triangle measurement emitted by the measurement signal from the sensor (S).
