[0003] The utility model aims at solving the demand problem of fast, accurate reset ball type in billiard match, provide a kind of billiard accurate reset device using hawk eye system, utilize the record of hawk eye to the initial position of each billiard on billiard table, utilize laser to mark in the initial position of billiard, guide referee to carry out fast, accurate reset to the billiard that moves.
[0004] The utility model solves the technical scheme that it adopts: a kind of billiard accurate reset device using hawk eye system, including billiard table, the billiard that has scattered on the table top of billiard table, hawk eye system for recording the position of billiard is arranged on the top of billiard table, the top of the table is provided with laser instrument, the laser instrument is connected with hawk eye system data, the laser instrument emits laser laser to billiard reset point coordinate.
[0005] The Hawk-Eye in billiards is an advanced video technology equipment mainly used to improve the fairness and watchability of the game. This technology captures the game scene through high-definition and high-speed cameras and uses computer image processing technology for analysis and interpretation to provide real-time and accurate data support for the referee. In billiards, Hawk-Eye technology can help referees determine whether the ball has landed accurately, thus making more fair judgments. In addition, Hawk-Eye technology is also used for television broadcasts to display the situation on the table in 3D form, allowing viewers to better understand the details of the game. With the development of technology, Hawk-Eye technology is increasingly widely used in billiards, not only improving the quality of the game, but also bringing a more perfect viewing experience to billiards. The principle of the Hawk-Eye system is not complex, but very precise. It mainly includes 8 to 10 high-speed black and white cameras, which are installed around the game site to capture the trajectory of the ball from different angles. In addition, there are four computers responsible for calibrating the field and dividing the game space into measurement areas with millimeter units. The shooting speed of each camera is as high as 2000 frames per second, and the captured data is transmitted to the main control computer after being calibrated by anti-shake software. The main control computer calculates the running route and landing point of the ball using these data and displays the simulated trajectory on the TV or in-field large screen in real time. The whole process from data collection to result demonstration takes no more than 10 seconds, with a resolution accuracy below 5 millimeters.
[0006] The operation of the laser instrument of the device is commanded by the Hawk-Eye system, which emits a beam of laser light to the reset target point, forming a light point on the billiard table as the billiard reset point, which serves as the basis for the referee to reset. When running this system, the referee first selects the target ball to be reset in the screen, and the Hawk-Eye system finds its initial position as the reset target point. This point has accurate coordinates on the virtual billiard table of the entire Hawk-Eye system, and the Hawk-Eye system can issue instructions to the connected laser instrument to emit a beam of laser light to the billiard table. The referee guides the reset by relying on the point indicated by the laser light on the billiard table.
[0007] As preferred, the reset block is further provided with an arc-shaped slot on one side, which is adapted to the outer diameter of the billiard ball, and the slot wall of the arc-shaped slot is provided with at least two laser sources with different angles, and the laser beams emitted by the laser sources form a convergence point at the center of the bottom surface of the arc-shaped slot, and the convergence point is coincident with the reset point of the billiard ball. When the reset block is not used, the billiard ball to be reset will block the reset point of the billiard ball on the billiard table during the reset process, so that the last reset distance needs to be controlled by the referee artificially, and when the reset point of the billiard ball is located at the edge of the billiard ball, the greater the inclination angle of the laser beam, the greater the blocking effect during the reset process of the billiard ball. When the reset block is used, the reset block emits a plurality of laser beams toward the center of the bottom surface of the arc-shaped slot, and when the reset block is placed on the billiard table, the plurality of laser beams intersect with each other, and the convergence point is coincident with the reset point of the billiard ball, so that the billiard ball to be reset can be reset quickly and accurately by being attached to the arc-shaped slot of the reset block, and then the reset block can be removed. When the reset block is not placed flat, the intersection of the plurality of laser beams cannot form a point, but a light spot or multiple points, so that it can be judged that the reset block is not placed flat, and the referee should adjust the reset block.
[0008] As preferred, the laser beams emitted by the laser sources are obliquely downward toward the center of the bottom surface of the arc-shaped slot.
[0009] As preferred, the arc of the arc-shaped slot is not more than 180 degrees.
[0010] As preferred, the laser sources are provided with a plurality of lasers on the side wall of the arc-shaped slot at equal intervals.
[0011] The utility model utilizes the laser instrument to emit laser light to guide the referee to reset the billiard ball according to the hawk eye data, and can realize quick and accurate reset of the billiard ball, and utilizes the secondary positioning of the reset block to solve the shielding of the laser instrument by the billiard ball.
