[0018] Explanation of icon numbers:

[0019] The objectives, features, and advantages of this invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0020] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of the present invention and are not intended to limit the present invention.

[0021] To better understand the technical solution of the present invention, a detailed description will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0022] The main solution of this invention is: to obtain the initial state of the cue stick and the ball; when the ball is detected to be hit, to determine the simulated scene the ball enters based on the initial state of the cue stick and the ball; and to obtain the trajectory of the ball in the simulated scene based on the simulated scene.

[0023] In this embodiment, for ease of description, the following description will focus on the identification controller as the execution subject.

[0024] Because existing golf ball trajectory simulation devices use relatively simple data collection and calculation methods, they are not accurate enough in calculating the movement of the golf ball, resulting in large errors. In addition, in a real golf course, including grass, sand, fairway, and green, the trajectory of the golf ball varies on different surfaces. However, existing golf ball trajectory simulation devices do not show significant changes in the trajectory of the golf ball when it enters different simulated scenarios. Therefore, the golf ball trajectory is not accurate enough, resulting in an unrealistic golf simulation training experience for users.

[0025] To address the issues of insufficient realism and lack of authentic physical feedback in existing technologies, the purpose of this invention is to enable users to experience the tactile, visual, and kinematic effects of interacting with the ball and the course (such as grass or sand) in a real golf setting during simulated golf shots. This includes the rolling resistance of the ball on different textured surfaces, the depth of its descent, and the changes in its movement in complex environments, thereby highly replicating the real golf experience.

[0026] Given the limitations of existing technologies in motion capture and simulation of environmental changes, this invention aims to accurately capture the initial state of the user's cue and ball through more precise monitoring technologies and algorithms. At the same time, it simulates the influence of environmental factors on the ball's trajectory in real time and accurately, making the ball's trajectory simulation more consistent with real physical laws and the user's actual shot.

[0027] This invention provides a solution that acquires the initial states of a golf club and a ball; when the ball is detected to have been hit, it determines the simulated scenario the ball enters based on the initial states of the club and the ball; and based on the simulated scenario, it obtains the ball's trajectory within that scenario. This invention first determines the target simulated scenario in which the golf ball enters multiple different simulated scenarios, and then determines the golf ball's trajectory within the target simulated scenario using a scenario model corresponding to that target scenario. Compared to existing technologies, this invention provides golf users with a more realistic, accurate, and cost-effective golf scenario simulation experience.

[0028] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or golf simulator capable of performing the above functions. The following description uses a controller as an example to illustrate this embodiment and the subsequent embodiments.

[0029] Based on this, embodiments of the present invention provide a method for simulating the trajectory of a golf ball, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the golf ball trajectory simulation method of the present invention.

[0030] In this embodiment, the golf ball trajectory simulation method includes steps S10 to S30: Step S10: Obtain the initial state of the cue stick and the ball; It should be noted that the above-mentioned clubs may be golf clubs, which are used by hand. It should be noted that the ball mentioned above can be a golf ball.

[0031] It is understood that the initial state mentioned above includes the initial state of the cue stick and the initial state of the ball. The initial state of the cue stick is the state from the start to the end of the stroke when the user holds the cue stick and strikes the ball. The initial state of the ball is the instantaneous state of the ball when it is struck by the cue stick.

[0032] In the specific implementation, the aforementioned visual sensor 4 captures images of the cue stick and the ball from different angles. Through stereo vision technology and image recognition algorithms (such as deep learning algorithms and object detection and segmentation algorithms), the hitting action and the initial state of the ball can be obtained more comprehensively and accurately, effectively solving the problem of inaccurate capture in the prior art.

[0033] Step S20: When it is detected that the ball has been hit, the simulated scenario into which the ball enters is determined based on the initial state of the cue stick and the ball.

[0034] It should be noted that the above simulation scenarios include grass scenarios, sand scenarios, and low-friction scenarios, among which the low-friction scenarios are further divided into fairway scenarios and green scenarios.

[0035] Understandably, the parameters of the various simulation scenarios described above differ. For example, the ground elasticity and friction, as well as the wind speed and drag in the air, vary from scenario to scenario.

[0036] In a specific implementation, when the ball is detected to be hit by the cue stick, the controller 1 calculates the three-dimensional coordinates, velocity, acceleration and other information of the ball's movement in the air based on the initial state of the cue stick and the ball. After analyzing and processing the various information, the specific simulated scenario that the ball enters is determined.

[0037] Step S30: Based on the simulated scenario, obtain the trajectory of the ball in the simulated scenario.

[0038] It should be noted that the above-mentioned trajectory is the trajectory of the ball in the above-mentioned simulated scenario calculated by the controller 1 and displayed by the display device 6.

[0039] In the specific implementation, based on the determined simulation scenario, the scene model corresponding to the simulation scenario is obtained. First, the initial motion state of the ball when entering the scene is calculated. Then, the initial motion state is used as the input value and substituted into the corresponding scene model to obtain the motion trajectory corresponding to the simulation scenario.

[0040] This embodiment provides a method for simulating the trajectory of a golf ball.

[0041] In one feasible implementation, step S20 may include steps S201 to S203: Step S201: When it is detected that the ball has been hit, the initial state of the cue stick at the time of the shot and the initial state of the ball at the time of the shot are obtained.

[0042] It should be noted that the initial state of the club at the moment of impact refers to the state of the club from the moment of takeoff to the moment of impact. It should be noted that the initial state of the ball when it is struck refers to the position and angle at which the ball contacts the cue stick.

[0043] In a specific implementation, when the ball is detected to be hit by the club, the state of the club from the start to the end of the stroke, as well as the position and angle of contact between the ball and the club, are obtained.

[0044] Step S202: The initial state of the cue stick when striking the ball and the initial state of the ball when being struck are used as input data. The target model is used to calculate the output data of the ball.

[0045] It should be noted that the above input data includes the distance and time from the start to the finish of the shot, as well as the position where the ball is hit and the angle of contact with the shot. It should be noted that the target model mentioned above can be a strut stability model, a neural network model, or a deep learning model, or it can be a motion trajectory prediction model, a collision vibration system model, etc.

[0046] It should be noted that the reference Figure 2 , Figure 3 as well as Figure 4 , Figure 2 This is a first structural schematic diagram of a golf simulation device according to an embodiment of the present invention; Figure 3 This is a schematic diagram of the second structure of the golf simulation device according to an embodiment of the present invention; Figure 4 This is a schematic diagram of the third structure of the golf simulation device according to an embodiment of the present invention; with the initial position of the ball as the origin, the space inside the entire golf simulation device is a three-dimensional space, and the output data is the three-dimensional coordinates, velocity, acceleration, angle and rotation of the ball before it enters the scene model.

[0047] In the specific implementation, the distance and time from the start to the finish of the cue stick, the position where the ball is hit, and the angle of contact with the cue stick are used as the input data and substituted into the target model for calculation to obtain the three-dimensional coordinates, velocity, acceleration, angle, and rotation of the ball before it enters the scene model.

[0048] Step S203: Determine the simulated scene into which the ball enters based on the output data.

[0049] In the specific implementation, the simulated scene into which the ball enters is determined based on the three-dimensional coordinates, velocity, acceleration, angle, and rotation of the ball before it enters the scene model.

[0050] In one feasible implementation, step S30 may include steps S301 to S302: Step S301: Obtain the corresponding scene model according to the different simulation scenarios.

[0051] It should be noted that the above simulation scenarios include grassland scenarios, sandy scenarios, and low-friction scenarios; It should be noted that the above scene models include grassland scene models, sandy scene models, and low-friction scene models corresponding to the above simulation scenarios. Understandably, different scenario models described above correspond to different ground hardness, ground roughness, ground humidity, air humidity, air wind speed, and air resistance.

[0052] In the specific implementation, corresponding scenario models are obtained according to different simulation scenarios. In the grass scenario, when the ball hits the grass, it bounces based on the ball's output data and the hardness of the grass. The bounce height and direction are calculated based on the ball's input data and the elasticity of the grass. When the ball rolls, the friction of the grass is related to the ball's speed. The grass scenario generates significant friction on the ball, resulting in a slow rolling speed, short distance, and a quick stop. In the sand scenario, the ball in a bunker is affected by the sand, potentially sinking into it and deviating in direction, significantly slowing its rolling speed. If the ball falls into a bunker, the friction in the sand scenario is much greater than in the grass scenario; the ball will "sink" into the sand, stopping or rolling at a very slow speed. In this case, the ball's motion is calculated based on the depth of contact between the ball and the sand and the sand's coefficient of friction. When the golf ball does not sink completely but rolls on the surface of a bunker, the friction calculation needs to be adjusted based on the looseness of the sand, the size and shape of the sand grains. The trajectory of the ball on sand is usually irregular, and the ball may "wobble" or change direction, resulting in a short rolling distance. The low-friction scenarios mentioned above also include fairway and green scenarios. In these scenarios, the grass is relatively flat, with a smooth and hard surface, resulting in low rolling friction, and the ball may continue to roll a longer distance. Compared to fairway scenarios, greens are flatter, harder, and have even less friction. In these low-friction scenarios, the rolling distance is calculated based on the ball's initial velocity, angle of incidence, and friction. Due to the low friction in these scenarios, the ball typically rolls a longer distance. The degree of surface preparation in the green scenarios may cause slight variations in the coefficient of friction in local areas; therefore, the low-friction scenario model needs to account for possible minor variations in the green surface.

[0053] Step S302: Calculate the motion pattern of the ball in the simulated scene according to the corresponding scene model to obtain the motion trajectory.

[0054] It should be noted that the above-mentioned grass scene uses a multi-layer composite artificial turf design. The length, density, and elasticity of the shorter fibers in the upper layer are specially designed to accurately simulate the rolling, bouncing, and other movements on the longer grass. This multi-layer composite artificial turf design overcomes the shortcomings of traditional grass simulations, which are merely simple planes and cannot realistically simulate the complex interactions between the ball and the grass (referring to its integration with software), and is one of the key innovations in improving the realism of the simulation. It should be noted that the aforementioned sandy terrain scenario uses specially formulated simulated sand material (with particle size, shape, and bulk density similar to real sand), which accurately simulates the depth to which the ball sinks, its rolling direction, and its speed in the sand, influenced by sand characteristics and environmental factors (this refers to its integration with software). This design solves the problem of traditional sand simulations lacking realism and accuracy, especially in its innovation in simulating the impact of the sandy environment on the ball's movement, thus enhancing the overall realism of the golf scenario simulation.

[0055] In the specific implementation, based on the corresponding scene model, the motion of the ball in the simulated scene is calculated to obtain the trajectory. The grass scene, the sand scene, and the low-friction scene are stitched together.

[0056] In one feasible implementation, step S302 may include steps S3021 to S3022: Step S3021: Switch the corresponding target impact pad according to the different simulated scenarios.

[0057] It should be noted that the aforementioned target impact pads include grass impact pads, sand impact pads, and low-friction impact pads.

[0058] Understandably, the aforementioned long-grass hitting mats are made with longer synthetic fiber filaments to mimic the resistance that the long grass on a real golf course exerts on the club and ball during impact. The aforementioned sand hitting mats are made with even longer and thicker synthetic fiber filaments, with larger gaps between the filaments, causing the ball to sink slightly when placed on the sand hitting mat, mimicking the sinking motion of a ball in real sand. The thicker and harder material also provides greater resistance to the club and ball during impact. The aforementioned low-friction hitting mats are made with shorter synthetic fiber filaments, allowing for better passage for the club and ball. The shorter filaments do not obstruct the club and ball, mimicking the effect of the short grass on a real golf course.

[0059] In specific implementation, the corresponding long grass hitting pad is switched according to the grass scene, the corresponding sand hitting pad is switched according to the sand scene, and the corresponding low friction hitting pad is switched according to the low friction scene. Among them, the long grass hitting pad provides greater resistance, simulating the drag of long grass on the club. When the user hits the ball, the club will feel obvious resistance, affecting the ball's flight distance and direction. The sand hitting pad provides medium resistance, simulating the obstruction of sand on the club. When the user hits the ball, the club will feel the resistance of sand grains, affecting the ball's flight trajectory and distance. The low friction hitting pad provides less resistance, simulating the less impact of short grass on the club. When the user hits the ball, the club feels less resistance, the ball flies more easily, and the flight distance and direction are closer to the ideal state.

[0060] Step S3022: When it is detected that the user hits the ball on the target hitting pad, the corresponding scene model is obtained.

[0061] In the specific implementation, when it is detected that the user hits the ball on the target hitting pad, the corresponding scene model can be obtained based on the target hitting pad, and then the subsequent motion trajectory of the ball can be calculated and analyzed based on the corresponding scene model.

[0062] In one possible implementation, step S30 may be followed by step S31': Step S31': Display the trajectory of the ball within the simulated scene using the display device 6.

[0063] In a specific implementation, after the user finishes hitting the ball, the display device 6 displays the image of the ball's trajectory within the simulated scenario.

[0064] In one possible implementation, step S31' may be followed by step S32': Step S32': Upon detecting the end of the ball's motion in the simulated scenario, reacquire the initial state of the cue stick and the ball.

[0065] In the specific implementation, after the ball's movement in the simulated scenario is detected to have ended, the initial state of the club and the ball is retrieved again, that is, after one golf simulation practice session ends, preparations are made for the next golf simulation practice session.

[0066] It should be noted that the above examples are only for understanding the present invention and do not constitute a limitation on the golf ball trajectory simulation method of the present invention. Any simple modifications based on this technical concept are within the protection scope of the present invention.

[0067] This invention also provides a golf ball trajectory simulation device, please refer to... Figure 5 The device includes: 2. Serving device; 3. Multi-scene hitting pad; 4. Visual sensor; 5. Projector; and 1. Controller. The controller 1 is connected to the ball-serving device 2, the multi-scene hitting pad 3, the visual sensor 4, and the projector 5, respectively.

[0068] It should be noted that the aforementioned visual sensor 4 contains a tri-lens camera, which plays a crucial monitoring role in the system. The three cameras capture images of the golf ball and the player's movements from different angles. Through stereoscopic vision technology, they can accurately capture the golf ball's position and trajectory in space. The high frame rate and high resolution of the tri-lens camera ensure data accuracy, clearly capturing details of the ball even at high speeds, such as markings on the ball's surface and its spin. It should be noted that the aforementioned ball-launching device 2, according to the user's settings or preset programs, raises the golf ball to the top of the tee with different parameters to simulate various situations during a real shot. It should be noted that the aforementioned multi-scenario hitting mat 3 includes a hitting mat simulating a rough scenario, a hitting mat simulating a sandy scenario, and a hitting mat simulating a low-friction area, with the aim of providing users with a more realistic golf training experience.
