Abstract:
1. A billiard game system, comprising: a simulative ball movably provided in a predetermined direction from a predetermined shot position as an object to be shot by a player; a plurality of image acquiring devices for outputting data on images of a predetermined detection range set in a direction in which the player shoots, which are scanned from viewpoints different from each other relevant to the simulative ball at the shot position; a coordinate computing device for computing, in a predetermined time period, a three-dimensional coordinate of at least two typical points of a cue in a three-dimensional coordinate system set with respect to the detection range based on data outputted from each image acquiring device; a position/angle specifying device for specifying a shooting point and a shot angle of the simulative ball based on the coordinate of the typical points of the cue computed by the coordinate computing device; a speed information detecting device for detecting information correlated with a speed of the simulative ball, wherein the speed information detecting device comprises sensors; a speed specifying device for specifying a speed at which the simulative ball has been shot based on information detected by the speed information detecting device; a link portion having a ball axis on which the simulative ball is capable of being mounted; a support portion for movably supporting the link portion; a predetermined chassis, wherein a table portion simulating a part of a table of a billiard base is provided at the chassis; an upper face of the table portion functions as a table face; a space opening forwardly of the table portion is formed by the table face and a hood covering the face; a simulative ball of the shot position is movable between the shot position and a standby position retracted to the depth of the space further than the shot position; and a respective one of the plurality of image acquiring devices is disposed in the hood or under the hood in a state in which a scanning direction is oriented more downwardly than a horizontal direction; and a computing device for computing an operation of a virtual cue ball to be displayed on a screen of a predetermined display unit in correspondence with the simulative ball based on the specified shooting point, angle, and speed, wherein a respective one of the plurality of image acquiring devices outputs data that corresponds to a projected image onto each scanning plane different from each other, the scanning planes being set in the three-dimensional coordinate system, and
