[0002] Nowadays, billiards has become a popular sport. It uses a cue to hit the ball on the billiard table, and the winner of the game is determined by calculating the score. However, for new billiards enthusiasts, their experience with billiards is limited, and they cannot accurately hit the billiard ball into the designated position, such as into the pocket, resulting in a low goal rate and a poor hitting experience.

Obviously, the drawings in the following description are some embodiments of the present application.

[0085] Figure 5 This is a schematic diagram of the composition of a billiard ball hitting assistance device provided by the embodiments of the present application. Detailed implementation manners

[0086] Existing billiard ball hitting assistance methods usually install a coaxial laser emitter on the cue to indicate the hitting direction and path to assist players in hitting the ball. However, the structure of the coaxial laser emitter on the cue is too simple, and its function and effect are extremely limited. For indirect hitting and conductive hitting, it is impossible to predict the ball path. Especially when there are multiple balls on the table, if the hitter lacks experience and faces multiple hitting path options, it is basically impossible to determine the best hitting line, resulting in a poor hitting assistance effect.

[0087] With the rapid development of machine vision and artificial intelligence technologies, the applicant has thought of applying them to the auxiliary prediction of billiard ball hitting routes to help inexperienced hitters more accurately determine the hitting line, improve the hitting assistance effect for users, and further increase the goal rate and hitting experience.

[0088] Specifically, to solve the above defects and improve the billiard ball hitting assistance effect, the present application provides a billiard ball hitting assistance method. First, an image of the target billiard table is obtained; among them, the image of the tabletop includes the cue ball and the object balls. Then, the image of the tabletop is recognized to determine the positions of the object balls that are on one's own side and the positions of the object balls of the other side. Next, based on the positions of the object balls on one's own side and the positions of the object balls of the other side, the best hitting route is predicted. Furthermore, at least one of the cue ball hitting route, the target object ball hitting route on one's own side, and the goal route can be projected on the tabletop of the target billiard table according to the best hitting route. It can be seen that since the embodiments of the present application can project at least one of the best hitting routes of the cue ball hitting route, the target object ball hitting route on one's own side, and the goal route according to the obtained dynamics of the target billiard table, the hitting assistance effect for users can be improved, and the goal rate and hitting experience are further enhanced.

[0089] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0090] First Embodiment

[0091] See Figure 1 , which is a schematic flowchart of a billiard hitting assistance method provided in this embodiment. The method includes the following steps:

[0092] S101: Obtain the desktop image of the target billiard table; wherein, the desktop image includes the cue ball and the object balls.

[0093] In this embodiment, in order to improve the assistance effect, first, imaging devices such as color cameras in the assistance system can be used to pick up the surface image of the target billiard table for performing the subsequent step S102.

[0094] Any billiard table that uses this embodiment to improve the hitting assistance effect is defined as the target billiard table. In order to improve the assistance effect, first, existing or future imaging devices, such as vision cameras (color is better), can be used to obtain the desktop image of the target billiard table for performing the subsequent step S102.

[0095] S102: Identify the desktop image to determine the positions of the object balls that are our own balls and the positions of the opponent's balls.

[0096] In this embodiment, after obtaining the desktop image of the target billiard table through step S101, further, existing or future image recognition methods can be used to identify the desktop image to determine which of the object balls on the desktop are our own balls, which are the opponent's balls, which is the cue ball, as well as the positions of the cue ball, our own balls, and the opponent's balls for performing the subsequent step S103.

[0097] S103: Predict the best hitting route based on the positions of our own balls and the positions of the opponent's balls.

[0098] In this embodiment, after determining the positions of the cue ball, our own balls, and the opponent's balls through step S102, further, based on the determined positions of the cue ball, our own balls, and the opponent's balls, it is used to perform the subsequent step S103.

[0099] S104: Project at least one of the cue ball hitting route, the target our own ball hitting route, and the scoring route on the desktop of the target billiard table according to the best hitting route.

[0100] In this embodiment, after predicting the best hitting route through step S103, further, by analyzing and processing the best hitting route, at least one of the cue ball hitting route, the target our own ball hitting route, and the scoring route projected on the desktop of the target billiard table can be determined according to the analysis and processing results, and existing or future projection devices can be used to project it onto the desktop of the target billiard table. For example, a laser pointer can be used to project at least one of the cue ball hitting route, the target our own ball hitting route, and the scoring route onto the desktop of the target billiard table.

[0101] Specifically, an optional implementation is that the specific implementation process of this step S104 may include the following steps S1041 - S1042:

[0102] S1041: Determine the rotation angle of the hitting route indicator according to the optimal hitting route.

[0103] In this embodiment, after predicting the optimal hitting route through step S103, further determine the rotation angle of the laser indicator that projects the optimal hitting route according to this optimal hitting route, that is, determine the rotation angles of the cue ball hitting route indicator, the target ball hitting route indicator, and the scoring route indicator according to the optimal hitting route, for performing the subsequent step S1042.

[0104] Among them, the hitting route indicator can be a laser emitter, which is used to emit a laser straight line of a color such as red or green.

[0105] S1042: Project at least one of the cue ball hitting route, the target own - side ball hitting route, and the scoring route on the tabletop of the target billiard table according to the rotation angle of the hitting route indicator.

[0106] In this embodiment, after determining the rotation angle of the hitting route indicator through step S1041, further project at least one of the cue ball hitting route, the target own - side ball hitting route, and the scoring route on the tabletop of the target billiard table according to the rotation angle of the hitting route indicator.

[0107] Specifically, an optional implementation is that the cue ball hitting route can be projected on the tabletop of the target billiard table according to the rotation angle of the cue ball hitting route indicator; and / or, the target own - side ball hitting route can be projected on the tabletop of the target billiard table according to the rotation angle of the target ball hitting route indicator; and / or, the scoring route can be projected on the tabletop of the target billiard table according to the rotation angle of the scoring route indicator.

[0108] In addition, in order to further improve the hitting assistance effect for the user, an optional implementation is that after predicting the optimal hitting route through step S103, the optimal cue ball hitting point position can also be predicted according to the positions of the cue ball, the own - side balls, and the opponent's balls, and a cue ball hitting point projection can be projected on the tabletop of the target billiard table according to this optimal cue ball hitting point position.

[0109] In addition, another optional implementation is that when the user hopes to independently select the target ball and wishes to view the optimal hitting route corresponding to the new target ball, in order to improve the user's hitting experience, the system can also obtain the user's voice command, and then re-predict the optimal hitting route according to the voice command. Next, the rotation angle of the hitting route indicator can be re-determined according to the re-predicted optimal hitting route. Furthermore, according to the re-determined rotation angle, at least one of the cue ball hitting route, the target own ball hitting route, and the scoring route can be re-projected on the tabletop of the target billiard table to assist the user in determining a more accurate hitting route, improving the scoring rate and the hitting experience.

[0110] In this way, the user can independently control and change the predicted hitting plan through voice. And at least one of the cue ball hitting route, the target own ball hitting route, and the scoring route is re-projected on the table through the hitting route indicator (such as a laser indicator), and combined with the projection of the cue ball hitting point already projected on the tabletop of the target billiard table, so as to assist the user in determining a hitting route that better meets their personalized requirements, realizing the combination of the intelligence of the above billiard hitting assistance method and the subjective initiative of the user, and improving the assistance effect and the user's hitting experience.

[0111] In summary, a billiard hitting assistance method provided in this embodiment first obtains the tabletop image of the target billiard table, where the tabletop image includes the cue ball and the object balls. Then, the tabletop image is recognized to determine the positions of the own balls and the opponent's balls among the object balls. Next, according to the positions of the own balls and the opponent's balls, the optimal hitting route is predicted. Furthermore, at least one of the cue ball hitting route, the target own ball hitting route, and the scoring route can be projected on the tabletop of the target billiard table according to the optimal hitting route. It can be seen that since the embodiment of the present application can project the optimal hitting route of at least one of the cue ball hitting route, the target own ball hitting route, and the scoring route according to the obtained dynamic of the billiard table of the target billiard table, the hitting assistance effect of the user can be improved, and the scoring rate and the hitting experience are further enhanced.

[0112] Second Embodiment

[0113] This embodiment provides a billiard hitting assistance system for implementing the billiard hitting assistance method provided in the first embodiment. Refer to Figure 2 , which is a structural diagram of a billiard hitting assistance system provided in this embodiment. The billiard hitting assistance system 200 is installed in the billiard lamp above the target billiard table, and specifically includes: an imaging device 201, a processor 202, a power supply 203, and a hitting route indicator 205 (such as Figure 2 the cue ball hitting route indicator 2051, the target ball hitting route indicator 2052, and the scoring route indicator 2053 in

[0114] Among them, the imaging device 201 is used to obtain the desktop image of the target billiard table; among them, the desktop image includes the cue ball and the object balls. And, in order to improve the effect of the batting assistance, the imaging device 201 can be set as a vision camera (color is better), such as Figure 3 shown, used to pick up the surface image of the target billiard table and feed it back to the processor 202.

[0115] The processor 102 is used to, after receiving the desktop image of the target billiard table fed back by the imaging device 101, use existing or future image recognition methods to recognize the desktop image to determine which of the object balls on the desktop are the player's own balls, which are the opponent's balls, which is the cue ball, as well as the positions of the cue ball, the player's own balls, and the opponent's balls.

[0116] Furthermore, the processor 202 is also used to, according to the determined positions of the cue ball, the player's own balls, and the opponent's balls, use the built-in artificial intelligence (AI) algorithm to predict the best batting route.

[0117] Among them, it should be noted that the processor 202 can adopt a central processing unit (CPU) with an AI algorithm built in, which is used for intelligent recognition of the entire billiard batting assistance system, algorithm analysis, and working signal indication of each component, etc.

[0118] The power supply 203 is used to supply power to the entire billiard batting assistance system 200. For example, a transformer and a battery pack can be used to provide power supply for the entire billiard batting assistance system 200.

[0119] The batting route indicator 205 is used to rotate a specific angle according to the best batting route predicted by the processor 202 and project the light rays in at least one corresponding specified direction of the cue ball batting route, the target player's own ball batting route, and the scoring route on the desktop of the target billiard table.

[0120] Among them, the batting route indicator 205 can be a laser indicator. And the laser indicator can specifically be a laser emitter, which is used to emit a laser straight line of a color such as red or green.

[0121] Specifically, in an optional implementation manner, the billiard batting assistance system 200 further includes a stepper angular displacement motor 204 (such as Figure 2 the cue ball stepper angular displacement motor 2041, the object ball stepper angular displacement motor 2042, and the scoring route angular displacement motor 2043 in), so that after the processor 202 predicts the best batting route, it can send the best batting route to the stepper angular displacement motor 204 (that is Figure 2The cue ball stepper angular displacement motor 2041, the object ball stepper angular displacement motor 2042, and the scoring route angular displacement motor 2043). So that the stepper angular displacement motor 204 can determine the rotation angle of the shot route indicator 205 according to the best shot route sent by the processor 202.

[0122] In this implementation, the stepper angular displacement motor 204 can be a motor that rotates at a certain angle for precise angle positioning. And the shot route indicator 205 is installed on the stepper angular displacement motor 204 so that the motor can drive the shot route indicator 205 to rotate to an appropriate angle. In this way, after the processor 202 calculates the best shot route, it may send a line signal to the stepper angular displacement motor 204. After the motor drives the shot route indicator 205 to rotate to a predetermined angle, the shot route indicator 205 emits light to indicate the running route of the corresponding billiard ball. And different angular displacement motors respectively control different shot route indicators to project different indication lines on the tabletop.

[0123] An optional implementation is, as Figure 2 and Figure 3 shown, the stepper angular displacement motor 204 can include a cue ball stepper angular displacement motor 2041, an object ball stepper angular displacement motor 2042, and a scoring route angular displacement motor 2043. The shot route indicator 205 can include a cue ball shot route indicator 2051, an object ball shot route indicator 2052, and a scoring route shot route indicator 2053.

[0124] Then the cue ball stepper angular displacement motor 2041 can determine the rotation angle of the cue ball shot route indicator 2051 according to the best shot route signal sent by the processor 202. Furthermore, the cue ball shot route indicator 2051 can project a cue ball shot route on the tabletop of the target billiard table according to this rotation angle.

[0125] And, the object ball stepper angular displacement motor 2042 can determine the rotation angle of the object ball shot route indicator 2052 according to the best shot route signal sent by the processor 202. Furthermore, the object ball shot route indicator 2052 can project an object ball shot route for one's own side on the tabletop of the target billiard table according to this rotation angle.

[0126] Also, the scoring route angular displacement motor 2043 can determine the rotation angle of the scoring route indicator 2053 according to the best shot route signal sent by the processor 202. Furthermore, the scoring route indicator 2053 can project a scoring route on the tabletop of the target billiard table according to this rotation angle.

[0127] It should be noted that the hitting route indicator 205 mentioned in the above embodiment introduction can be a laser indicator; the cue ball hitting route indicator 2051 can be a cue ball laser indicator; the object ball hitting route indicator 2052 can be an object ball laser indicator; the goal route indicator 2053 can be a goal route laser indicator. Then, laser lines corresponding to the specified directions of the cue ball hitting route, the object ball hitting route of one's own side, and the goal route are projected on the tabletop of the target billiard table.

[0128] On this basis, in order to further improve the hitting assistance effect for users, in a possible implementation manner of the embodiment of the present application, as Figure 2 or Figure 3 shown, the billiard hitting assistance system 200 further includes a cue ball hitting point indicator 206. In this way, after the processor 202 predicts the optimal cue ball hitting point position based on the positions of the cue ball, the balls of one's own side, and the balls of the other side, it can send a signal of the optimal cue ball hitting point position to the cue ball hitting point indicator 206, so that the cue ball hitting point indicator 206 projects a cue ball hitting point projection on the tabletop of the target billiard table in response to this signal, as Figure 4 shown, to assist the user in more accurately determining the hitting position of the cue ball.

[0129] In addition, an alternative implementation manner is that when the user hopes to independently select an object ball and hopes to view the optimal hitting route corresponding to the new object ball, in order to improve the user's hitting experience, as Figure 2 or Figure 3 shown, the billiard hitting assistance system 200 further includes a voice interaction module 207. The voice interaction module 207 can be a module device such as a microphone with a sound pickup function to achieve a sound pickup effect, and is specifically used to obtain the user's voice command and send the voice command to the processor 202. In this way, the processor 202 can re-predict the optimal hitting route according to the voice command and send the re-predicted optimal hitting route to the stepper angular displacement motor 204, so that the stepper angular displacement motor 204 can re-determine the rotation angle of the hitting route indicator 205 according to the re-predicted optimal hitting route. Furthermore, the hitting route indicator 205 can re-project at least one of the cue ball hitting route, the object ball hitting route of one's own side, and the goal route on the tabletop of the target billiard table according to the re-determined rotation angle, assisting the user in determining a more accurate hitting route and improving the goal rate and hitting experience.

[0130] In this way, through the voice interaction module 206, the user can autonomously control and change the predicted hitting plan by voice. And at least one of the cue ball hitting route, the object ball hitting route of one's own side, and the goal route is re-projected on the billiard table through the hitting route indicator 205, combined with as Figure 4The hitting point projection shown can assist the user in determining a hitting line that better meets their personalized requirements, thereby combining the intelligence of the billiard hitting assistance system 200 with the user's subjective initiative, thereby improving the assistance effect and the user's hitting experience.

[0131] Next, in order to facilitate understanding of the billiard hitting assistance system 200 provided by the present application, the present application will introduce in detail the specific assistance process of the billiard hitting assistance system 200 by way of examples:

[0132] For example: Assuming that the tabletop size of the target billiard table and the distance between the billiard lamp and the tabletop are standard fixed values, the imaging device 201 (such as a visual camera) is located at the center of the table. According to the pre-adjusted parameters, the tabletop panoramic view is overlooked in real time, and the tabletop image of the target billiard table is obtained in real time, that is, the positioning information of the billiard balls on the tabletop is picked up, and the suits of the billiard balls on the tabletop are identified at the same time to determine the current ball, one's own ball and the opponent's ball.

[0133] On this basis, assume that the billiard ball movement scene on the target billiard table is as follows Figure 4 As shown, first, the imaging device 201 (such as a visual camera) obtains the desktop image of the target billiard table and transmits it to the processor 202. Then, the processor 202 first determines that 12 is the mother ball, 13 and 21 are the own balls, and 14 and 15 are the opponent's balls according to the AI ​​algorithm, and then performs AI calculation on the mother ball 12, the own ball 13 and the pre-set table hole orientation to obtain the best shot movement route, and transmits the signal of the best shot movement route to the mother ball stepping angular displacement motor 2041, the target ball stepping angular displacement motor 2042, and the goal route angular displacement motor 2043 respectively.

[0134] Next, the cue ball stepping angular displacement motor 2041 drives the cue ball hitting path indicator 2051 to rotate to a reasonable angle, and projects the cue ball path 25 (i.e., the cue ball hitting path) indicated by a dark gray thick arrow on the target billiard table; at the same time, the target ball stepping angular displacement motor 2042 drives the target ball hitting path indicator 2052 to rotate to a suitable angle, and projects the target ball path 16 (i.e., the target own ball hitting path) on the target billiard table; and, the goal path angular displacement motor 2043 drives the goal path indicator 2053 to rotate to a suitable angle, and projects the goal path 17 on the target billiard table.

[0135] Moreover, the processor 202 can predict the optimal hitting point position of the cue ball based on the position of the cue ball, the position of the player's own balls, and the position of the opponent's balls, and send the signal corresponding to this position to the cue ball hitting point indicator 206, so that the cue ball hitting point indicator 206 can project the cue ball hitting point projection 19 on the tabletop of the target billiard table in response to this signal to assist the user in determining the position to hit the cue ball. Among them, the cue ball hitting point projection 19 specifically includes five different points A / B / C / D / E on the cue ball 12 that can be hit, and the arrow to the left of D indicates the hitting direction of the cue stick. When hitting different points A / B / C / D / E on the cue ball 12, it will cause the cue ball to have different movement routes. For example, when hitting the middle position A of the cue ball 12, the cue ball 12 will move forward in a straight line. When hitting the upper-middle position B of the cue ball 12, the cue ball 12 will move forward and continue to move forward. When hitting the lower-middle position D of the cue ball 12, the cue ball 12 will move forward and then return a certain distance in the reverse direction. When hitting the middle-left position E of the cue ball 12, the cue ball 12 will move to the right in an arc. When hitting the middle-right position C of the cue ball 12, the cue ball 12 will move to the left in an arc. Accordingly, at least one of the cue ball route 25 (i.e., the cue ball hitting route), the object ball route 16 (i.e., the object player's own ball hitting route), and the scoring route 17 on the target billiard table can be used to assist the user in judging the final and more accurate hitting path. At the same time, according to the projected cue ball hitting point projection 19, assist the player in determining the position E to hit the cue ball, so as to realize the optimal hitting route composed of the cue ball route 25 (i.e., the cue ball hitting route), the object ball route 16 (i.e., the object player's own ball hitting route), and the scoring route 17.

[0136] At this time, if the user does not want to select the hitting route composed of the cue ball route 25 (i.e., the cue ball hitting route), the object ball route 16 (i.e., the object player's own ball hitting route), and the scoring route 17, but hopes to independently select an object ball to hit and view the optimal hitting route corresponding to the new object ball, then a voice command (such as "calculate the route of ball No. X", etc.) can be issued first.

[0137] Then, after the voice interaction module 207 obtains this voice command issued by the user, it can transmit it to the processor 202. Then, the processor 202 can re-predict the optimal hitting route, that is, hit the object ball 21, based on the desktop image fed back by the imaging device 201 (such as a vision camera) in combination with the AI algorithm. At the same time, transmit the hitting signals corresponding to this re-predicted optimal hitting route to the cue ball step angular displacement motor 2041, the object ball step angular displacement motor 2042, and the scoring route angular displacement motor 2043 respectively.

[0138] Next, the cue ball stepping angular displacement motor 2041 drives the cue ball hitting route indicator 2051 to rotate to a reasonable angle, and projects the cue ball route 26 (i.e., the re-predicted cue ball hitting route) indicated by a light gray thick arrow on the target billiard table; at the same time, the object ball stepping angular displacement motor 2042 drives the object ball hitting route indicator 2052 to rotate to an appropriate angle, and projects the object ball route 22 (i.e., the re-predicted hitting route of the target own ball) on the target billiard table; and, the goal route angular displacement motor 2043 drives the goal route indicator 2053 to rotate to an appropriate angle, and projects the goal route 23 (i.e., the re-predicted goal route) on the target billiard table.

[0139] Moreover, the processor 202 can, according to the re-predicted position of the best cue ball hitting point, send the signal corresponding to this position to the cue ball hitting point indicator 206, so that the cue ball hitting point indicator 206 can, in response to this signal, project the cue ball hitting point projection 19 on the tabletop of the target billiard table to assist the user in re-determining the position of hitting the cue ball. The specific determination process is similar to the above method and will not be elaborated here. Accordingly, at least one of the re-predicted cue ball route 26 (i.e., the re-predicted cue ball hitting route), the object ball route 22 (i.e., the re-predicted hitting route of the target own ball), and the goal route 23 (i.e., the re-predicted goal route) on the target billiard table can be used to assist the user in re-judging the final hitting path that meets their personalized needs. At the same time, according to the projected cue ball hitting point projection 19, the player can be assisted in re-determining the accurate cue ball hitting position to achieve the preferred hitting route composed of the cue ball route 26, the object ball route 22, and the goal route 23.

[0140] In summary, a billiard hitting assistance system provided in this embodiment includes an imaging device, a processor, a power supply, and a hitting route indicator. Among them, the imaging device is used to obtain the tabletop image of the target billiard table; the tabletop image includes the cue ball and the object balls; the processor is used to identify the tabletop image, determine the positions of the own balls and the opponent's balls among the object balls, and predict the best hitting route according to the positions of the own balls and the opponent's balls; the hitting route indicator is used to project at least one of the cue ball hitting route, the hitting route of the target own ball, and the goal route on the tabletop of the target billiard table according to the best hitting route; the power supply is used to supply power to the billiard hitting assistance system. It can be seen that since the embodiment of the present application obtains the dynamic state of the target billiard table through the imaging device and projects the best hitting route through the hitting route indicator, its hardware device is simple. Only through the intelligent analysis of the processor can the best ball route be given and the corresponding hitting indication line be projected, thereby improving the hitting assistance effect of the user and further enhancing the goal rate and hitting experience.
