[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figure 1 The embodiments of this utility model include:

[0020] like Figure 1 The modular high-speed ball-hitting monitoring system with replaceable host computer shown includes: host computer 1, data cable plug 2 and slave computer. The data cable plug 2 is fixed or movably connected to the slave computer by a cable. The host computer 1 is provided with a first socket that can be hot-swapped with the data cable plug 2, which can be quickly plugged into the data cable plug 2, making it convenient to replace the host computer 1.

[0021] In this embodiment, the host computer 1 is one of a touch screen, a smartphone, or a tablet computer. The lower-level computer is connected to the host computer 1 via a data cable plug 2. Simultaneously, the lower-level computer can act as a power source to supply power to the host computer 1, such as a 5-20V PD power supply. The choice of host computer 1 is flexible; players do not need to repeatedly log into their accounts and can simply plug in their smartphones to use the software for training, improving ease of use.

[0022] In addition, the touch screen is equipped with AI, and the smartphones and tablets also have OTG functionality, enabling hot-swapping and switching of the host computer 1.

[0023] The data cable plug 2 uses a USB Type-C plug, which can be plugged into most touch screens, smartphones and tablets, or connected through an adapter, making it widely applicable.

[0024] The lower-level machine includes an FPGA computing unit 4, a high-speed image acquisition unit, and an infrared illumination unit 5. The FPGA computing unit 4 is connected to both the high-speed image acquisition unit and the infrared illumination unit 5. In this embodiment, the infrared illumination unit 5 uses either a VCSEL pulsed laser light source or an LED array light source, offering flexibility in selection. The VCSEL pulsed laser light source can meet the illumination requirements for high-speed ball-hitting monitoring, while the LED array light source can meet the needs of low-cost application scenarios.

[0025] like Figure 1 As shown, the lower-level machine also includes a housing 7, and the FPGA computing unit 4 is disposed in the housing 7. The FPGA computing unit 4 includes a circuit board, an FPGA chip, a power module and an interface module. The FPGA chip is embedded on the circuit board. The power module and the interface module are respectively connected to the circuit board to provide power and connect to other devices. The structure is compact and the total system power is <12W.

[0026] In this embodiment, the high-speed image acquisition unit includes a first high-speed camera 3 and a second high-speed camera 6. The first high-speed camera 3, the infrared illumination unit 5, and the second high-speed camera 6 are arranged vertically on one side of the housing 7. The frame rate of the first high-speed camera 3 and the second high-speed camera 6 is ≥800 fps. During the high-speed ball hitting process, the first high-speed camera 3 and the second high-speed camera 6 capture images of the same scene from different perspectives. After image matching and calculation, three-dimensional depth information is generated, which can build a high-precision three-dimensional environment model for ball hitting monitoring and perform key image screening. In a single ball hitting event, only 3 to 4 key images can be sent to the host computer 1. The size of each frame does not exceed 0.3 MB, and the transmission is completed within 5 ms. The host computer 1 has a built-in or calls a neural network inference unit of no less than 2 TOPS and outputs the ball speed, launch angle, and three-dimensional spin results within 5 ms, with a fast response speed. Example

[0027] The data cable plug 2 is fixed to the housing 7. The housing 7 is provided with a mechanical guide mechanism or locking mechanism corresponding to the host computer 1. The host computer 1 is directly plugged into the data cable plug 2 and positioned by the mechanical guide mechanism or locking mechanism, which ensures high stability.

[0028] In this embodiment, the data cable plug 2 can be connected to the FPGA computing unit 4 through the wiring inside the housing 7, which is convenient for maintenance. Alternatively, the data cable plug 2 can be soldered onto the circuit board of the FPGA computing unit 4, which has a high degree of integration but is inconvenient for maintenance. Example

[0029] The data cable plug 2 is movably connected to the lower-level computer, offering good flexibility. For convenient cable storage and use, the lower-level computer has a second socket corresponding to the cable. One end of the cable is fitted with the data cable plug 2, which plugs into the upper-level computer 1, while the other end is fitted with a quick-connect plug that plugs into the second socket. The quick-connect plug can also be a USB Type-C plug, similar to the data cable plug 2, allowing for blind insertion and cable detachment for easy storage and portability.

[0030] In this embodiment, the cable is an E-Marker cable, equipped with an E-Marker chip, supports fast charging, and has USB 3.0 or higher transmission performance.

[0031] In summary, the modular high-speed ball-hitting monitoring system with replaceable host computer disclosed in this utility model adopts a modular design, and the host computer and slave computer can be quickly plugged in and separated, facilitating the switching of the host computer. It is highly portable and enables the monitoring of high-speed ball-hitting during golf training.

[0032] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
