Description

Technical Field

[0001] This utility model relates to the field of sports auxiliary equipment technology, and in particular to a billiards reset auxiliary device. Background Technology

[0002] In table tennis competitions, when the ball needs to be reset, the traditional method of relying on the referee's manual observation and memory or simple tools for positioning is prone to insufficient reset accuracy due to subjective errors and limitations in the observation angle. Moreover, the operation is time-consuming and affects the smoothness of the game. Therefore, a more accurate and efficient auxiliary device is needed, which is the background technology of this device.

[0003] There are three types of existing table tennis resetting devices: a television screen mirror resetting system with no independent hardware, which relies on a person to reset by referring to the fixed screen; an image recognition-based positioning device that includes a table with coordinates, a camera, and a computer, which uses the camera to capture the ball position and transmits the data to the computer for processing and storage to guide the resetting; and a laser positioning diffraction light source device that consists of optical elements and an XY linear slide, which uses a laser diffraction light source for positioning and assisting in the resetting.

[0004] Traditional devices are complex to disassemble, which means that a lot of time is required to disassemble them when they need to be moved to other tables, stored or repaired. The positioning device in the billiards reset auxiliary device cannot be moved, which means that it can only be adapted to billiards tables in fixed positions, making it difficult to flexibly adapt to different table layouts or multi-table rotation scenarios. Therefore, a billiards reset auxiliary device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a billiard ball reset auxiliary device, which aims to improve the problems of complex disassembly and immobile positioning device in the prior art.

[0013] Reference Figures 1-3The control module 14 includes a support block 8, which is fixedly connected to the top of the control module 14.

[0014] Working principle: Used to assist in billiard ball reset, the device's high-definition camera 16 is connected to the control module 14, which can monitor the billiard table in real time. When the ball stops moving, it automatically records the ball's position. One end of the control module 14 is connected to an infrared head 15. The infrared color is not limited to red and can be set to single infrared or multiple infrared. Single infrared requires hitting the ball one by one, while multiple infrared can mark all ball positions at once. The other end is connected to the fixing post 13 and forms a rigid connection with the buckle box 12. The buckle box 12 has a fixing plate 11 fixed inside. The fixing plate 11 has two buckles 19 on its inner side. During assembly, the buckles 19 are snapped into the fixing box 9 to complete the connection. When disconnecting, simply press the sliding buckle 10 to make the buckles 19 detach from the fixing box 9 for quick separation. The sliding plate 1 has a sliding groove 2 with a horizontal and vertical bidirectional layout. The fixing post 13 can drive the high-definition camera 16 and other related components to move stably along the sliding groove 2. The fixing post 13 is connected to the support rod 7 and the support block 8 respectively. One end is connected to movable rod 4, which is equipped with roller 3. The other end is connected to movable rod 6, which is equipped with roller 5. Through the cooperation of roller 3, roller 5 and sliding groove 2, the overall structure can slide smoothly. The device is divided into two types: small and large. The small device is installed only in the center above the table and does not need to cover the entire table. The infrared head 15 can be moved slightly by the program to achieve the point of contact on the table. The disadvantage is that the infrared head 15 is not perpendicular to the table, which may cause the laser to appear to be deviated. However, it can still play an auxiliary role in resetting based on the point of contact of the laser on the table. The large device needs to cover the entire table. The infrared head 15 can be moved to the designated ball position directly above the ball position through the above sliding structure to achieve vertical contact and improve the accuracy of resetting. When resetting is required, the operation control module 14 can trigger the infrared head 15 to emit infrared light to the table according to the previously recorded ball position to assist in the resetting of the billiard ball.

[0015] In addition, a high-definition camera 16 can be used to assist in resetting the billiard ball. A projection device is installed on the side of the high-definition camera 16 and connected to the control module 14. The control module saves, processes, and transmits the photos taken by the high-definition camera 16 to the projection device. The high-definition camera 16 monitors the billiard table in real time. When the ball stops moving, it automatically records the ball's position and takes an image of the ball's stopping position for subsequent resetting. When the billiard ball needs to be reset, the control module 14 controls the projection device to turn on the image according to the user's instructions and projects it onto the billiard table. The projection position matches the shooting position and angle of the high-definition camera 16. After projection, the billiard ball can be reset with assistance.
