Abstract

The invention discloses a restoration device for billiards. The restoration device comprises a support which is arranged above a billiard table in a vertical corresponding mode and further comprises a controller. Cameras capable of shooting the whole table surface are mounted on the support, beams capable of moving along the length or width direction of the support are mounted on the support through a main translation mechanism, positioning lamps which move along the beams and capable of casting light spots are mounted on the beams through an auxiliary translation mechanism, and by means of the controller, a coordinate system corresponding to the billiard surface in a picture shot by the cameras can correspond to a coordinate system corresponding to the moving range of the positioning lamps, and the light spots cast by the positioning lamps can be moved to table surface positions corresponding to center positions of specified billiard balls. The restoration device is reasonable in structure, capable of indicating restoration positions accurately, small in restoration error, simple to operate, applicable to various billiard training, particularly applicable to professional billiards such as Snooker and capable of improving fairness and shortening restoration time.
