[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] Reference Figure 1-Figure 4 An automatic tracking device for a football match based on a drone includes a drone body 1. The drone body 1 adopts a six-axis design. This design enables the drone body 1 to have better stability and flight control ability during flight, and can maintain a stable flight state even under complex wind conditions, thereby ensuring the shooting quality of the football match.

[0025] The fuselage 11 of the drone body 1 is equipped with a camera 12 with high-definition image quality and fast response characteristics, which can capture the movement trajectory of the football and the exciting moments of the game in real time, and transmit the images in real time to external devices such as TVs, computers or mobile phones, so that viewers can watch or record the game.

[0026] In order to ensure that the drone body 1 has sufficient power during flight, a power unit 13 is installed on the arm of the drone body 1. The power unit 13 includes a driving unit 131 installed on the fuselage 11 on the arm. The driving unit 131 adopts a high-performance brushless motor with the characteristics of high torque, low noise and long life. The output end of the driving unit 131 is connected to a propeller 132. The propeller 132 is made of lightweight materials and has excellent aerodynamic performance to provide sufficient lift and thrust to ensure that it can stably hover, rise and fall, move forward, retreat and turn.

[0027] At the same time, considering that the drone body 1 can provide stable support before taking off, a pair of retractable landing gear 14 is designed on the drone body 1. The landing gear 14 is made of lightweight alloy material, which is not only structurally strong but also extremely light, effectively reducing the overall load of the drone body 1. Once the drone body 1 successfully takes off and enters the flight state, the landing gear 14 will automatically retract. This design not only reduces the air resistance encountered by the drone during flight, improves the flight efficiency, but also reduces the energy consumption caused by the friction between the landing gear and the air, thereby extending the flight time of the drone.

[0028] The football unit 2 is an indispensable part of a football match, and the design of the football body 21 is particularly critical. In order to improve the accuracy and efficiency of the drone body 1 in tracking and shooting the football body 21 during the game, a plurality of eye-catching identification layers 22 are specially added to the surface of the football body 21. These identification layers 22 not only enhance the recognition of the football in the drone camera 12, but also enable the drone camera 12 to quickly lock the position and movement trajectory of the football. Moreover, its unique design also brings a clearer and more vivid viewing experience to the audience.

[0029] Specifically, the main color of the football body 21 is black or dark gray. This dark background forms a strong contrast with the green grass background commonly seen in football match fields, making the football unit 2 more visually prominent. On the basis of black or dark gray, a plurality of white or light gray identification layers 22 are evenly distributed on the surface of the football body 21. These identification layers 22 use a high-contrast color combination to ensure that they remain clearly visible under different light and angles. The design of the identification layer 22 takes into account the rotation and rolling of the football unit 2 to ensure that no matter what state the football unit 2 is in, sufficient details can be captured by the camera 12 to achieve accurate tracking and recording.

[0030] In a preferred embodiment, referring to Figure 4 A sensor module 23 is installed in the inner cavity of the football body 21. The circumference of the football body 21 is between 68 cm and 70 cm, and the weight is between 410 g and 450 g. This is because FIFA stipulates that the mass of the match ball is between 410 g and 450 g. Therefore, the football body 21 is made of a lighter plastic material, and the sensor module 23 used is about 50 g. Therefore, the mass of the football unit 2 can be controlled between 430 g and 450 g, which meets FIFA's regulations on match balls.

[0031] In order to ensure that the sensor module 23 can be stably fixed in the central area inside the football body 21, 13 or 14 fixed wires 24 are used to connect the football body 21 and the sensor module 23. The material of these fixed wires 24 can be any one of elastic wire, nylon wire or metal wire to ensure that they can maintain a stable fixed state under different movement and vibration conditions. Among them, the sensor module 23 uses a Bluetooth attitude angle measurement sensor, which can collect the acceleration and movement direction of the football body 21 and has the function of transmitting signals. It is equipped with a lithium battery with a battery life of about 2 hours. The communication method is Bluetooth 2.0. The effective communication distance is about 50 meters, which can meet the signal transmission requirements.

[0032] During the game, the sensor module 23 monitors the acceleration, speed, direction and other motion data of the football in real time, and transmits these data to the drone body 1 in real time through wireless communication technology. Based on these data, the drone body 1 can accurately predict the movement trajectory of the football and dynamically adjust the flight path and the shooting angle of the camera 12 to ensure that the football unit 2 is always within the optimal shooting range. This design not only improves the viewing experience of the football game, but also provides valuable data support for game analysis and tactical research.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
