Description

Technical Field

[0001] The invention relates to the technical field of three-dimensional models, and in particular to a billiard memory simulation replay demonstration system and a billiard table thereof. Background Art

[0002] Billiards memory simulation review is a technology that helps players review the game process, analyze tactics and improve techniques by recording and reproducing every shot action and ball trajectory in billiards. In the prior art, many technologies are used for video and motion capture of shots, but these technologies are used in isolation and have many disadvantages, such as poor review effects and scenes, resulting in poor visualization effects.

[0003] Prior art 1, application number: CN 201910358938.3 discloses a computer-based automatic demonstration control device, including a base, and a force bearing seat is installed on the right side of the base. The computer-based automatic demonstration control device transmits the billiard ball on the top frame to fall through the conduit, and the piston block is pressed to move downward inside the piston cylinder, thereby driving the sealing push plate to move to the right inside the sealing cylinder through the compressed gas medium, pushing the push column to move to the right, and pushing the billiard ball in the lower ball tube into the upper ball tube one by one. In the process of large-scale detection and demonstration, the billiard ball is pushed out of the upper ball tube, and the pressed billiard ball is transmitted to the inside of the conduit through the ball guide groove for detection. Although the kinetic energy generated during the collision detection process of the billiard ball itself is used to realize the automatic loading and detection of the billiard ball one by one, it is suitable for large-scale automatic detection of billiard balls, which improves the effect of the automatic detection demonstration of the device. However, its automatic demonstration function is limited to the detection of billiard balls, and the billiard ball memory replay cannot be realized, and the reproduction of the hitting action and trajectory cannot be realized, which makes the function of the scheme relatively single and the automatic control ability is poor.

[0004] Prior art 2, application number: CN 201110312228.0 discloses a projection-type billiard training system and its implementation method, including a billiard table, an image acquisition device, a billiard lamp and a projection device; the head end of the image acquisition device installed in the billiard lamp is level with the lower end of the lamp, and is hung at a certain height on the billiard table facing the center of the billiard table; the projection device is hung beside the billiard lamp and controlled by a computer; the implementation method of the system: establish a standard database of training courses and related image files; when the system program is running, by selecting elementary to advanced training courses, read the above data and files, and the projection device displays the required demonstration video, auxiliary lines, billiard position, aiming point, cue ball and target ball simulated motion trajectory and other images on the billiard table; when training according to the image, the image acquisition device captures the hitting video, sends it to the computer for analysis, and gives the next hitting suggestion. Although it makes billiard training more scientific, accurate, intuitive and convenient, thereby improving billiard hitting accuracy and cue ball control ability. However, its three-dimensional sense of display is poor, it cannot reproduce the distant view, and lacks the experience of the game.

[0005] Prior art three, application number: CN 201310401018.8 discloses an elliptical billiard table, which is achieved by the following measures: the inner edge of the rubber table edge is an ellipse (not strictly speaking, ordinary people can see it as an ellipse with their eyes), the inner edge of the table edge baffle is the outward offset curve of the ellipse (top view), the offset distance is equal to the width of the rubber table edge, and holes are set at the maximum and minimum curvature of the ellipse, a total of 4 holes. Although it meets the needs of miniaturized teaching, its function and structure are relatively simple, and it cannot realize the dynamic demonstration of replay, and cannot effectively improve the level of automation control of the billiard table.

[0006] At present, the existing technologies 1, 2 and 3 have poor visualization effects on the hitting routes and trajectories of billiards, and cannot reproduce the entire process of billiards. Therefore, the present invention provides a billiards memory simulation replay demonstration system and a billiard table, with a built-in three-dimensional billiard model. During the billiards movement, the billiards movement is recorded and saved throughout the process, and the recorded billiard hitting and moving routes are converted to the three-dimensional billiard model.
