[0022] With the popularity of indoor golf simulation systems, more and more golf enthusiasts choose to practice and entertain in indoor environments. One of the core devices of indoor golf simulation systems is the golf ball detection system, which is responsible for monitoring the movement of the golf club and the ball when the player uses the golf club to hit the golf ball, and then calculates the reasonable movement data of the golf club and the ball and simulates the flight trajectory of the ball.

[0023] In the existing system, due to the limited frame rate, in some fast-hitting scenes, when the hitting speed is extremely fast, only 2-3 images of the ball movement are captured, which may lead to low accuracy in identifying and calculating the ball flight process. It may also cause the loss or blurring of the images at the critical hitting moment, affecting the accurate analysis of the hitting action, and thus leading to calculation errors or inability to calculate the results. On the other hand, data accuracy still needs to be improved. Possible factors include calibration errors between cameras, the impact of changes in ambient light on image quality, and some noise interference during data processing. These problems may lead to misjudgment during data comparison, such as misidentifying the movement of objects in non-hitting areas as hitting, which in turn affects the player's experience.

[0024] In order to solve the above problems, the present invention proposes a three-eye camera device and a golf simulation device, which aims to provide a three-eye camera device and a golf simulation device that can more accurately and comprehensively detect the hitting area and the movement process of the golf ball. Figure 1 to Figure 2 A schematic structural diagram of an embodiment of a three-eye camera device provided by the present invention.

[0025] Please refer to Figure 1 to Figure 2 In one embodiment of the present invention, the three-eye camera device 100 includes a substrate 1, a visual acquisition device 2 and a main control board 3; the substrate 1 is arranged in an elongated shape and is provided with a mounting end surface 11; the visual acquisition device 2 includes three high-definition cameras 21, and the three high-definition cameras 21 are arranged at intervals and fixed on the mounting end surface 11 on the substrate 1; the main control board 3 is fixed on the mounting end surface 11 on the substrate 1 and is electrically connected to the visual acquisition device 2; wherein the three high-definition cameras 21 constitute a three-eye stereo system, and transmit the collected image information to the main control board 3 for monitoring the hitting area.

[0026] The technical solution of the present invention is to arrange the three high-definition cameras 21 at intervals and fix them on the mounting end surface 11 on the substrate 1. At the same time, the main control board 3 is electrically connected to the visual acquisition device 2, so that the image information collected by the three high-definition cameras 21 is transmitted to the main control board 3 for monitoring the hitting area. As a result, the three high-definition cameras 21 form a three-eye stereo system, which can obtain image information in a larger range and more accurately, thereby improving the accuracy and reliability of golf club and golf ball detection and improving the player's experience.

[0027] The hardware design core of the three-eye camera device 100 is to use FPGA technology. FPGA has parallel processing capabilities and can efficiently process multiple data streams. In the three-eye stereo system, three high-definition cameras 21 at different angles are connected. The high-definition camera 21 is a high-frame rate camera that can clearly capture the picture of the hitting area, and due to the characteristics of the high frame rate, more photos can be obtained per unit time. From the working principle, the high-definition cameras 21 work at the same time and shoot the hitting area from their respective angles. Whenever a hitting action occurs, the light signal captured by the high-definition camera 21 is converted into an electrical signal, and then digitized into image data. These image data are transmitted to the FPGA in real time via a high-speed data transmission line. With its advantage of parallel operation, FPGA simultaneously processes the image data from the high-definition camera 21, compares and analyzes them, thereby realizing the detection of the hitting area and shooting the movement of the golf club and the golf ball.

[0028] On the one hand, the existing visual acquisition device, whether it is a monocular camera system or a binocular camera system, has the problem of insufficient frame rate. In some fast-hitting scenes, when the hitting speed is extremely fast, the number of images of the ball movement captured by the low frame rate is only 2-3, which may lead to low accuracy in identifying and calculating the ball flight process. At the same time, because of the low frame rate, the image of the key hitting moment may be lost or blurred, affecting the accurate analysis of the hitting action, and then leading to calculation errors or failure to calculate the result. On the other hand, the data accuracy of the prior art is not high. Possible factors include calibration errors between cameras, the impact of changes in ambient light on image quality, and some noise interference during data processing. These problems may lead to misjudgment during data comparison, such as misidentifying the movement of objects in non-hitting areas as hitting. The three-eye camera device 100 optimizes the performance of the visual acquisition device 2 and improves the algorithm, not only improves the frame rate, but also increases the number of image acquisitions, so that the subsequent calculation of ball speed, rod speed, take-off angle, backspin, and side spin based on these data, as well as the simulation evaluation of flight trajectory, flight distance, and landing angle, etc., are more accurate and reliable. Specifically, the frame rate of the high-definition camera 21 can reach about 1000 frames per second, which optimizes the data transmission line and adopts FPGA for efficient data transmission and processing, ensuring that a large amount of image data can be quickly and stably transmitted from the camera to the subsequent processing unit. The realization of high frame rate solves the problem of image loss or blurring at the critical moment of hitting the ball in the fast hitting scene. In the actual hitting test, when the hitting speed exceeds the camera capture limit of the original solution, the new solution can clearly capture the contact state of the golf ball and the club at the moment of hitting the ball, the deformation of the ball and the club, and the movement process, etc., providing accurate data for subsequent analysis.

[0029] In the present application, the high-definition camera 21 has the characteristic of high frame rate, that is, compared with the prior art, more image data can be obtained in the same time period, and the more image data, the more helpful the accuracy and reliability of the detection; and, in the three-eye camera device 100, a three-eye design is adopted to shoot the hitting area from more angles, which further improves the accuracy and comprehensiveness of the data. In terms of software algorithms, more image data provides a basis for more complex and accurate algorithms, and the motion process of the ball and the calculation of related parameters can be more accurately identified through deep learning analysis of a large number of images. At the same time, the more image data brought by the high-definition camera 21 to increase the frame rate are used to improve the software algorithm, and a large amount of image data is mined and analyzed through more complex deep learning algorithms or other data analysis methods, so as to further improve the recognition ability of the hitting action, the calculation accuracy of the related parameters of the hitting position and the ball flight process, and make the detection and analysis of the golf ball by the whole system more accurate and reliable. At the same time, the algorithm is optimized to process the data, and the influence of noise interference caused by environmental factors or hardware itself on the accuracy of the data is reduced.

[0030] In addition, the high-definition camera 21 also uses a large-target sensor, whose photosensitive element can receive more light. This improvement enables the high-definition camera 21 to capture clear, high-quality images in low-light environments. This setting further improves the accuracy and stability of image data acquisition.

[0031] For further information, please refer to Figure 1 and Figure 2 , the three high-definition cameras 21 are arranged in sequence along the length direction of the substrate 1 and are arranged in a collinear manner. It can be understood that in order to make the three-eye camera device 100 easy to process and have a neat and beautiful appearance, the three high-definition cameras 21 are arranged in the same side and in a collinear direction, so that the three high-definition cameras 21 can acquire images of objects within their orientation range with the same reference line, so that the acquired images are accurate, and because the three high-definition cameras 21 are arranged in a straight line, the arrangement process is simple, neat and concise. It should be noted that in other specific embodiments, the positional relationship between the three high-definition cameras 21 is not limited. The three high-definition cameras 21 can be arranged in a straight line, can be arranged in an irregular shape, or can be arranged in a triangular shape.

[0032] Furthermore, the layout and installation structure of the three-eye stereo system are optimized. Through precise mechanical design and calibration, the relative position and angle between the three high-definition cameras 21 are ensured to be more accurate. In the manufacturing process, high-precision molds and assembly processes are used, thereby reducing the difficulty of installing the three-eye camera device 100. The structure of this optimized three-eye stereo system can shoot the hitting area from different angles more accurately, avoiding data errors caused by the position or angle deviation of the high-definition camera 21, and further improving the accuracy and stability of the data compared to the prior art. In practical applications, whether it is the edge part or the center part of the hitting area, the optimized three-eye stereo system can more accurately capture the position and movement state of the ball, reducing the image deformation and data inaccuracy caused by the perspective deviation.

[0033] For further information, please refer to Figure 1 , the high-definition cameras 21 at the two end sides of the three high-definition cameras 21 are tilted toward the high-definition camera 21 in the middle. It can be understood that in order to obtain accurate images, the high-definition cameras 21 at the two end sides of the three high-definition cameras 21 are tilted toward the high-definition camera 21 in the middle. Such a setting is conducive to the three-eye camera device 100 to obtain a three-dimensional image, thereby making the obtained visual data more accurate and more stable. In this way, this multi-view data acquisition method can better restore the batting scene, provide more abundant and accurate materials for subsequent software algorithms, and provide players with a good experience.

[0034] In addition, in the present application, the software algorithm and the hardware improvement are closely coordinated and optimized. In the case of the high frame rate of the high-definition camera 21, the processing speed of the algorithm is also optimized accordingly. By parallelizing the algorithm and optimizing the code, the computing resources are fully utilized to ensure that a large amount of image data can be processed in time, avoiding data accumulation and processing delays. At the same time, the software algorithm is adjusted in a targeted manner according to the characteristics of the camera after the hardware improvement. For example: the basic motion detection of the ball adopts a binocular combination (including flight speed, flight angle, etc.); different camera combinations are used in different areas, and the corresponding combination of cameras is started according to the physical area where the ball is located, and the synchronous video frames collected by the camera are obtained, and the binocular algorithm processing is performed; the high-definition camera 21 is divided into processing the motion information of the ball and the club, including (the club face angle and the hitting angle at the moment of the club hitting the ball, etc.).

[0035] In addition, please refer to Figure 1 and Figure 2, the three-eye camera device 100 also includes a light source device 4, which is installed on the installation end surface 11 to provide light for the three high-definition cameras 21. It can be understood that in some usage scenarios, if the light is sufficient, the three-eye camera device 100 can obtain good image data, and thus will not affect the reliability of the subsequent software algorithm. However, in some dim scenes, due to insufficient light, the high-definition camera 21 cannot obtain accurate image data, which causes errors in the subsequent software algorithm or fails to calculate the path of the golf ball, thereby affecting the player's experience. Therefore, the three-eye camera device 100 also includes the light source device 4, which is installed on the installation end surface 11 to provide light for the three high-definition cameras 21, thereby further ensuring that the high-definition camera 21 can obtain accurate and clear image data, thereby ensuring the accuracy and reliability of the data.

[0036] For further information, please refer to Figure 1 and Figure 2 , the light source device 4 includes a lamp board 41, which is fixed on the substrate 1, and a plurality of light source components 411 are embedded on the lamp board 41, and the plurality of light source components 411 are arranged in an array. It can be understood that in order to enable the high-definition camera 21 to obtain accurate and clear image data, thereby ensuring the accuracy and reliability of the data, the light source device 4 includes the lamp board 41, which is fixed on the substrate 1, and through the setting of the lamp board 41, light is provided for the shooting of the high-definition camera 21, so that the three-eye camera device 100 obtains accurate image data; specifically, the plurality of light source components 411 are embedded on the lamp board 41, and the plurality of light source components 411 are arranged in an array. It can be understood that in order to ensure the light intensity and uniformity of the light source provided, the plurality of light source components 411 are embedded on the lamp board 41, and the plurality of light source components 411 are arranged in an array, so that the clarity and accuracy of the image information are further guaranteed.

[0037] For further information, please refer to Figure 1 and Figure 2, the light source device 4 includes a driving board 42, which is electrically connected to the main control board 3, and is used to electrically drive the light source component 411. It can be understood that the intensity of the light source component 411 is adjustable, and the opening and closing of the light source component 411 also requires conditions. Therefore, the light source device 4 includes the driving board 42, which is electrically connected to the main control board 3, and is used to electrically drive the light source component 411. Specifically, the driving board 42 can determine when to turn on the light source component 411 according to the intensity of the ambient light, that is, when the ambient light intensity is weaker than the preset value, the driving board 42 turns on the light source component 411, and when the ambient light intensity is stronger than the preset value, the driving board 42 turns off the light source component 411. It can also be adjusted according to the intensity of the ambient light, so as to always maintain the optimal light intensity, so that the high-definition camera 21 can always obtain clear and accurate image information.

[0038] For further information, please refer to Figure 1 and Figure 2 , the light boards 41 are provided in plurality and are arranged at intervals along the length direction of the substrate 1. It can be understood that the visual acquisition device 2 is provided with three high-definition cameras 21 to form a three-eye stereo system, and thus, the image information acquired by each high-definition camera 21 requires a suitable light environment, and thus, the light boards 41 are provided in plurality and are arranged at intervals along the length direction of the substrate 1, thereby ensuring that at least each high-definition camera 21 has a corresponding light board 41, thereby ensuring the accuracy and clarity of the image information acquired by each high-definition camera 21.

[0039] In addition, please refer to Figure 1 The three-eye camera device 100 further includes a first baffle 5 and a second baffle 6 arranged at the periphery of the substrate, and the first baffle 5 and the second baffle 6 are both protruding from the mounting end surface 11. It can be understood that the mounting end surface 11 is basically provided, and the visual acquisition device 2 and the main control board 3 are installed on the mounting end surface 11. Since the visual acquisition device 2 includes the three high-definition cameras 21, the camera lenses of the three high-definition cameras 21 are relatively fragile. In order to protect the high-definition cameras 21 from being damaged by external factors such as bumps, the three-eye camera device 100 further includes the first baffle 5 and the second baffle 6, and the first baffle 5 and the second baffle 6 are both protruding from the mounting end surface 11, so as to surround the mounting end surface 11, thereby protecting the high-definition cameras 21, and further ensuring the safety and reliability of the high-definition cameras 21.

[0040] For further information, please refer to Figure 1 and Figure 2The three-eye camera device 100 further includes a switch 51, which is mounted on the first baffle 5 or the second baffle 6 and is electrically connected to the main control board 3. It can be understood that the three-eye camera device 100 is further provided with the switch 51, which is electrically connected to the main control board 3 to determine and drive the opening and closing of the entire three-eye camera device 100. Specifically, in this embodiment, the switch 51 is mounted on the first baffle 5.

[0041] The present invention further proposes a golf simulation device 200, which includes the three-eye camera device 100. The specific structure of the three-eye camera device 100 refers to the above embodiment. Since the golf simulation device 200 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0042] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
