Technical field
The present invention relates to a kind of billiard repositioning device.
Background technology
The meaning of Snooker (Snooker) is " obstruction, obstacle ", so snooker is also sometimes referred to as the obstacle billiard ball.Ball table that this motion is used is about 3569 millimeters, wide 1778 millimeters, and respectively there is a match play four jiaos of table tops and center, two long limits, and the ball of use is divided into 1 Archon, and 15 red balls and 6 colour balls (yellow, green, brown, blue, powder, deceive) are totally 22 balls.Batting order is that a red ball, a colour ball all pocket up to red ball, bats one by one with yellow, green, brown, blue, pink, black order then, and be victory with the high person of score at last.Snooker prevails in British commonwealth of nations and Hong Kong such as Britain, Ireland, Canada, Australia and India.
In the Snooker match, according to " Foul and Miss " (foul and a miss) rule, when side when foul arranged in the opposing teams, the opposing party requirement judge that has the right returns to ball-type before the foul with ball-type, just billiard repositioning is batted by the side continuation of foul then.At this moment, the judge will recover one or several ball that foul causes moving, and this just requires to judge the possibility that the side in foul will charge a foul in advance and remembers at that time ball-type before not breaking the rules.Sometimes the judge lacks experience, and can not estimate contingent foul, and it is more that perhaps foul causes mobile ball, and the judge just is difficult to ideally recover ball-type.Cause both sides sportsman easily to the disagreement of ball-type this moment, so just reduced or improved the difficulty of offending side continuation batting, loses the match fairness.
Owing to there is not special-purpose billiard repositioning device, recover ball-type in the current Snooker match, the one, by judge's experience and memory, the 2nd, by the video recording of coming to matches, the accuracy that both recover ball-type is lower, and error is bigger.
China Patent No. is that 200910082442.4 patent of invention discloses a kind of billiard repositioning method based on image matching technology, this method is mainly frequently taken pictures, is contrasted, shows that by computer the error of billiard ball position in the front and back picture that resets progressively resets by camera, the operation number of resets is more, resetting time is longer, and the judge needs frequent coming and going between ball table and the computer screen, it is bigger to consume one's strength, and reseting precision is difficult to guarantee.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of rational in infrastructure at above-mentioned deficiency, and accurately indication reset position, reset error are little, and billiard repositioning device simple to operate.
For solving the problems of the technologies described above, these billiard ball resetting means comprises the corresponding support that is arranged on ball table top up and down, the camera that can take whole ball table desktop picture is installed on the support, by main translation mechanism the crossbeam that can move along stent length or width is installed on the support, be equipped with along crossbeam by secondary translation mechanism on the crossbeam and move and can be at the positioning lamp of ball table desktop irradiation hot spot, also comprise the coordinate system that camera can be clapped ball table desktop correspondence in the picture coordinate system corresponding with the positioning lamp moving range one by one corresponding and with positioning lamp institute light projector spot move to picture in the controller of corresponding desktop position, appointment billiard ball center.
These billiard ball resetting means is to realize accurately that by the corresponding indicating arrangements of two coordinates indication reset position, reset error are little, and simple to operate.
The corresponding indicating arrangement of two coordinates refers to be provided with in these billiard ball resetting means two cover coordinate systems and a cover designation system.Wherein, a cover coordinate system is corresponding with the length and width size of billiard table desktop, for convenient narration, this coordinate system is called ball table coordinate system or desktop coordinate system.Ball table coordinate system is by being taken pictures in advance by camera, being undertaken determining after data are handled by the controller that receives camera signal then.Because camera is to be fixedly mounted on the support of ball table top, ground is actionless relatively, so when billiard table lay finish after, the position relation of camera and ball table desktop is fixing, the photo that camera is taken and ball table desktop are exactly one-to-one relationship, and the ball table coordinate system after handling through controller data is also just set up thereupon.In the ball table coordinate system, the photograph that the position of any point is taken according to camera by controller determines that camera pixel is more high, and the precision of ball table coordinate system is more high.
Another set of coordinate system is with corresponding by the moving range of the rack-mount positioning lamp of crossbeam, is convenient narration, and this coordinate system is called elements of a fix system or hot spot coordinate system.Elements of a fix system controls crossbeam by controller by main translating device and positioning lamp vertically moves and laterally move definite by controller by secondary translating device control positioning lamp.In the elements of a fix system, the position of each point is corresponding to the position of positioning lamp.The elements of a fix are the transmission accuracy that the height of precision depends primarily on each drive disk assembly.
One cover designation system comprises that mainly the positioning lamp that is installed on the crossbeam and positioning lamp are radiated at the hot spot on the ball table desktop.The main effect of designation system is to be judge's indicator console ball position by positioning lamp irradiation hot spot on the table, thereby realizes the function of auxiliary billiard repositioning.Designation system is by controller control work, and is used with elements of a fix system.
Controller is the core of these billiard ball resetting means, and it mainly acts on is to handle by internal data above-mentioned two coordinate systems are mapped, and just the location point in desktop coordinate system and the elements of a fix system is mapped one by one.Like this, when the billiard repositioning situation occurring, controller just can move to corresponding position in the elements of a fix system with positioning lamp by main translation mechanism and secondary translation mechanism according to the position of billiard ball in the desktop coordinate system in the preceding photo of foul.At this moment, positioning lamp is radiated at the accurate position that the facula position on the ball table desktop is exactly billiard ball before the foul.Like this, the judge is when resetting, and the billiard ball center that only needs to reset gets final product with the center of hot spot is corresponding, just billiard ball is placed on spot center and gets final product, and operates very simple.After the judge placed billiard ball, hot spot just was radiated on the billiard ball that will reset.At this moment, whether the judge can be positioned at the billiard ball top by observing spot center, can judge whether billiard ball accurately reset, and need not to check screen prompt or other promptings, and it is quicker to reset, and reseting precision is higher.If there are a plurality of billiard ball to reset, behind a billiard repositioning, controller can be controlled camera and take pictures and contrast the billiard repositioning front-back direction, if within allowable error, then controls the positioning lamp flicker or automatically hot spot is moved on the billiard ball position that the next one will reset.When all billiard repositionings finished, controller control positioning lamp extinguished, and match is normally carried out.
